This spring hibernate integration tutorial is focused on usage of Hibernate with Spring framework. I will show that how a basic end to end application flow looks like as a result of this integration.
1. Development environment
For those, who are not using maven for dependency management and are relying on downloaded jar files. I have created another project with all required jar files included in source code to download. Also, I have done integration using Spring 3.2.5 and hibernate 4.
So if you fall into any of above two category, please read below linked post in case any problem. Spring + Hibernate 4 integration tutorial with all jar files
To build this example project, I will guide you step by step. In this way we able to walk through some concepts also.
2. Create maven web project
Create a maven web project using below command from command prompt.
$ mvn archetype:generate -DgroupId=com.howtodoinjava.app -DartifactId=Spring3HibernateIntegration -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
Now convert this web project to ecplise dynamic web project using below maven command.
$ cd Spring3HibernateIntegration $ mvn eclipse:eclipse -Dwtpversion=2.0
3. Maven dependecies
Update pom.xml file to include spring and hibernate dependencies. It will also include mysql driver added in project references.

4. Create database schema
Now lets decide out database schema structure because it will be needed when we will write the entity classes in next step.
CREATE TABLE EMPLOYEE
(
ID INT PRIMARY KEY AUTO_INCREMENT,
FIRSTNAME VARCHAR(30),
LASTNAME VARCHAR(30),
TELEPHONE VARCHAR(15),
EMAIL VARCHAR(30),
CREATED TIMESTAMP DEFAULT NOW()
);
5. Write hibernate entity classes
Now its time to write EmployeeEntity. This class will be mapped to Employee table in database using hibernate. JPA will include any class annotated with @Entity in the persistence management setup. You don’t need persistence.xml if you use annotations.
package com.howtodoinjava.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="EMPLOYEE")
public class EmployeeEntity
{
@Id
@Column(name="ID")
@GeneratedValue
private Integer id;
@Column(name="FIRSTNAME")
private String firstname;
@Column(name="LASTNAME")
private String lastname;
@Column(name="EMAIL")
private String email;
@Column(name="TELEPHONE")
private String telephone;
//Setters and getters
}
6. Write data access code
Lets write our DAO classes which will be responsible for database interaction. This class will be essentially using the hibernate session factory for database interaction. The session factory implementation will be injected into reference variable at runtime using spring IoC feature.
package com.howtodoinjava.dao;
import java.util.List;
import com.howtodoinjava.entity.EmployeeEntity;
public interface EmployeeDAO
{
public void addEmployee(EmployeeEntity employee);
public List<EmployeeEntity> getAllEmployees();
public void deleteEmployee(Integer employeeId);
}
package com.howtodoinjava.dao;
import java.util.List;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import com.howtodoinjava.entity.EmployeeEntity;
@Repository
public class EmployeeDaoImpl implements EmployeeDAO
{
@Autowired
private SessionFactory sessionFactory;
@Override
public void addEmployee(EmployeeEntity employee) {
this.sessionFactory.getCurrentSession().save(employee);
}
@SuppressWarnings("unchecked")
@Override
public List<EmployeeEntity> getAllEmployees() {
return this.sessionFactory.getCurrentSession().createQuery("from EmployeeEntity").list();
}
@Override
public void deleteEmployee(Integer employeeId) {
EmployeeEntity employee = (EmployeeEntity) sessionFactory.getCurrentSession().load(
EmployeeEntity.class, employeeId);
if (null != employee) {
this.sessionFactory.getCurrentSession().delete(employee);
}
}
}
I have written a manager layer also which seems redundant in this demo due less complexity but it as always considered best practice if you write this. This layer will simply take call from controller and pass this call to dao layer.
package com.howtodoinjava.service;
import java.util.List;
import com.howtodoinjava.entity.EmployeeEntity;
public interface EmployeeManager {
public void addEmployee(EmployeeEntity employee);
public List<EmployeeEntity> getAllEmployees();
public void deleteEmployee(Integer employeeId);
}
package com.howtodoinjava.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.howtodoinjava.dao.EmployeeDAO;
import com.howtodoinjava.entity.EmployeeEntity;
@Service
public class EmployeeManagerImpl implements EmployeeManager
{
@Autowired
private EmployeeDAO employeeDAO;
@Override
@Transactional
public void addEmployee(EmployeeEntity employee) {
employeeDAO.addEmployee(employee);
}
@Override
@Transactional
public List<EmployeeEntity> getAllEmployees() {
return employeeDAO.getAllEmployees();
}
@Override
@Transactional
public void deleteEmployee(Integer employeeId) {
employeeDAO.deleteEmployee(employeeId);
}
public void setEmployeeDAO(EmployeeDAO employeeDAO) {
this.employeeDAO = employeeDAO;
}
}
7. Spring controller and view files
Now its time to write the spring controller and handler methods which will actually be called from spring framework’s dispatcher servlet to process actual application logic.
package com.howtodoinjava.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import com.howtodoinjava.entity.EmployeeEntity;
import com.howtodoinjava.service.EmployeeManager;
@Controller
public class EditEmployeeController
{
@Autowired
private EmployeeManager employeeManager;
@RequestMapping(value = "/", method = RequestMethod.GET)
public String listEmployees(ModelMap map)
{
map.addAttribute("employee", new EmployeeEntity());
map.addAttribute("employeeList", employeeManager.getAllEmployees());
return "editEmployeeList";
}
@RequestMapping(value = "/add", method = RequestMethod.POST)
public String addEmployee(@ModelAttribute(value="employee") EmployeeEntity employee, BindingResult result)
{
employeeManager.addEmployee(employee);
return "redirect:/";
}
@RequestMapping("/delete/{employeeId}")
public String deleteEmplyee(@PathVariable("employeeId") Integer employeeId)
{
employeeManager.deleteEmployee(employeeId);
return "redirect:/";
}
public void setEmployeeManager(EmployeeManager employeeManager) {
this.employeeManager = employeeManager;
}
}
Now we will write our application’s view layer which is actually a .jsp file.
<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%>
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>

<h2>Employee Management Screen : Spring 3 hibernate integration example on www.howtodoinjava.com</h2>
<form:form method="post" action="add" commandName="employee">

</table>
</form:form>
<h3>Employees</h3>
<c:if test="${!empty employeeList}">
<table class="data">

</tr>
<c:forEach items="${employeeList}" var="emp">

<td>${emp.email}</td>
<td>${emp.telephone}</td>
<td>delete</td>
</tr>
</c:forEach>
</table>
</c:if>
</body>
</html>
8. Spring dispatcher servlet
Our java code is complete and now its time to configure the application. Lets start from web.xml. In web.xml, we will configure the front controller for spring framework that is DispatcherServlet.
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"

<welcome-file-list>
<welcome-file>/WEB-INF/index.jsp</welcome-file>
</welcome-file-list>
<servlet>

</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>

</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
9. Spring hibernate integration configuration
Lets configure spring framework for hibernate data source, message resources, view resolvers and other such things.
<?xml version="1.0" encoding="UTF-8"?>

Hibernate configuration becomes simple when using annotation.
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<mapping class="com.howtodoinjava.entity.EmployeeEntity"></mapping>
</session-factory>
</hibernate-configuration>
10. JDBC Properties
Lets mention jdbc connection properties and message resource properties.
jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.dialect=org.hibernate.dialect.MySQLDialect jdbc.databaseurl=jdbc:mysql://127.0.0.1:3306/test jdbc.username=root jdbc.password=password
label.firstname=First Name label.lastname=Last Name label.email=Email label.telephone=Telephone label.add=Add Employee label.menu=Actions label.title=Employee Form label.footer=www.HowToDoInJava.com
That’s it. Your application is ready to be deployed on server of your choice. At the end, your project structure should look like this.
If you find any issue in building or running this spring hibernate integration example in eclipse step by step, drop em a comment and I will try to help you.
Update:
If you are facing issue :: “java.lang.NoClassDefFoundError: Lorg/hibernate/cache/CacheProvider”
Possible Solution: Please try changing org.springframework.orm.hibernate3.LocalSessionFactoryBean to org.springframework.orm.hibernate4.LocalSessionFactoryBean

Hi,
I am facing this error when I run spring and hibernate integration in eclipse:

hi, could you show an example of integrating jsf, spring and hibernate? Thank you
Lokesh Gupta
Added in my TODO list.
Davis
Hi Lokesh,
I created a project in Eclipse Luna. I picked jboss-javaee6-webapp-ear-archtype. I dropped the sample code in the respective folders.Project builds with out errors. But I am getting following errors.
Initialization of bean failed; nested exception is java.lang.ClassCastException: org.springframework.transaction.annotation.Propagation cannot be cast to org.springframework.transaction.annotation.Propagation
Lokesh Gupta
Never heard of this error. I will try to find a solution for it. As of now, I have no clue.
Davis
Is there any way I can send a screen shot of my project structure ?
My best guess is, it is due to following keywords in spring-servlet.xml.
Lokesh Gupta
Send me at howtodoinjava@gmail.com
Davis Alengaden
Hi Lokesh,
I could fix the issue. As I had picked jboss-javaee6-webapp-ear-archtype ,
there were three projects in the project structure – ear, ejb and war. Each project has its own porm and one main porm. I had same porm entries in multiple pom.xml which caused the issue. I removed redundant entries and dropped your project in appropriate folders in sync with archtype…. everything works fine now.
Thank you
Davis

Create a file messages_pl.properties with content of messages_en.properties (you can translate the values as well) in resources folder.
Ricardo
Hello!
How could I make a simple and efficient way to handle exceptions returned from my oracle database through the spring? Would use the DataAccessException? Thank you!!
Lokesh
Personally, I am not big fan of DataAccessException. I usually like to have more control over exceptions using @ExceptionHandler approach.
If you are looking to translate oracle exception codes directly then YES, DataAccessException is good way. If you are more concerned about handling exceptions, then try second approach.
Ricardo
I am not able to intercept the exception. He goes straight. Already put in catch ConstraintViolationException, Exception and DataAccessException but does not work. Would have any examples of how you did?
Following error:
Lokesh
This thread will help you if you not gone through it already. TODO: Catch the exception outside transaction boundary. This exception is not thrown by spring managed bean. Rather hibernate’s transactionmanager is throwing it from some proxy object.
Badal
Getting below error. Please help!!!
Lokesh
Please use latest spring jars; and remove any older versions if any.

“GET /Spring3HibernateIntegration/ HTTP/1.1″ 404
Something bad happened during deployment i.e. startup time in tomcat. Please check server logs. Are there any error while startup?
prem
Consider there are multiple requests. Since same instance of the servlet runs and Spring bean (EmployeeManager) isnot thread safe..How Spring bean thread-safety is taken care.
@Autowired
private EmployeeManager employeeManager;
Lokesh
Above variable (and other similar data as well) is not stateful data. Except initialization, no thread will ever change/modify it. Usually Manager and DAO layer classes never store any stateful data which is changed by any thread. And until you have any stateful data which can possibly be corrupted, never worry about multi-threading issue.
prem
Thanks, got it now.

SEVERE: Context initialization failed
Hi,
I am getting above error while trying to run the application in eclipse. Have added all necessary jars.
Please help where i am going wrong in this..
Lokesh
“java.lang.NoClassDefFoundError: ch/qos/logback/core/joran/spi/JoranException” says all. Logback dependency is missing..
vinayak
Check once your .jar file in the WEB-INF/lib foloder..
Abhijeet
HI Lokesh very nice explanation and helpful though.
I have question: when you return a list of Employee Entity you are returning it from singleton employeeManager as you are not Specifying any scope to it, but while the list changes how does it ensure that the singleton returns the new list every time a a request is made as singleton objects only constructed once .
Thanks in advance !!!
Lokesh
Singleton pattern should only be concern when object is stateful. Stateless objects do not need to be singleton in applications (usually). You will read good information here: https://howtodoinjava.com/for-fun-only/a-birds-eye-view-on-how-web-servers-work/
Abhijeet
Hi Lokesh, I meant to say what if the Employee Entity returns a Prototype Bean what if the list changes frequently. and how that would be handled if its constructed as Signleton Bean
Lokesh
EmployeeEntity as well as list of entities, is created always by hibernate and totally depends on number of rows obtained as result of query executed. Spring does not create either List of entities, or single entity. And Hibernate always create a new instance of list after query execution.
I hope I understood your concern right, this time 🙁 . Please let me know if I am still not able to clear your doubt.
Abhijeet
Yes that answers my question how does it works in case of Springs leave alone the Hibernate just Spring i wanted to know how can be a prototype bean may always give new value when its a dependency in an Singleton Bean … means when you try get a singleton bean when it has a prototype bean added as dependency
Lokesh
“Lookup Method injection” is there exactly for this purpose. See a good example here: https://prasanthnath.wordpress.com/2013/03/21/injecting-a-prototype-bean-into-a-singleton-bean/
Abhijeet
Thanks Lokesh for all you explanations this is simply amazing and thanks a lot for helping me 🙂

Thank You for great example of integration. It’s one of the best sources of knowledge in this topic as far I’ve found.
Good luck and

how can we handle multiple controller in our code ?
Lokesh
You can have multiple classes annotated with @Controller. Is it something else you are seeking?
JEYASEKAR
where/what i need to change?
Am using java 1.6.
Lokesh
Don’t know the root cause but adding this to pom.xml should solve the issue.
<build> <pluginManagement> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>2.3.2</version> <configuration> <source>1.6</source> <target>1.6</target> <compilerArgument></compilerArgument> </configuration> </plugin> </plugins> </pluginManagement> </build>Doreen
Hi thanks for this tutorial,
i met with this error, you do know whats causing the issue?
HTTP Status 500 – Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Cannot open connection
Lokesh
Connection can not be opened. Please verify your db credentials.
Doreen
i’ve tried googling about the error, and made changes in the jdbc.properties as well as employee-servlet.xml but it still doesnt works. any idea?
Dinesh
Thanks for your tutorial.
I’m the beginning of spring and hibernate. I want to learn the basic of spring and hibernate. Can you tell me which is a helpful tutorial (Which you are written) or books to learn the spring and hibernate basic concepts?
I only know the core Java concept.
Thanks in Advance.
Srikanth
Hi Lokesh, I’ve tried your code,but getting that Entity class given in mapping tag of hibernate.cfg.xml is not loading …causes hibernate mapping exception…. .might be am in wrong way…could you please help me out… thanks in advance…
Ambet
Thank you Mr. Lokesh, Nice blog for beginners! I was just wondering what do you use in wordpress to post the code blocks?
Lokesh
Plugin name is SyntaxHighlighter Evolved
Venky
Good job Mr. Lokesh, Also please post one sample application on Struts 1.x, Spring and Hibernate Integration in real time level.
Lokesh
May be it will help you. It is using struts 2 in tutorial, but you can easily replace the pieces from specific to struts 2 to struts 1.
https://howtodoinjava.com/struts-2/spring-4-struts-2-hibernate-integration-tutorial/
Venky
Thanks for your post, Mr Lokesh, I will let you know if i need any clarifications.

Hi Mr Lokesh, thank you for your tutorial it helps me to understand Maven
But i have error when i compile; i used your code 100% without changed anything
I use netbeans not Eclipse and i have this error

Lokesh
Have you tried the solution I suggested in last of post in first red block.
If you are facing issue :: “java.lang.NoClassDefFoundError: Lorg/hibernate/cache/CacheProvider”
Possible Solution: Please try changing org.springframework.orm.hibernate3.LocalSessionFactoryBean to org.springframework.orm.hibernate4.LocalSessionFactoryBean
Aina G
Hi Mr Lokesh,
Thank you for responding so quickly, i did it and i have two errors:
First error is :
can you give me your e-mail? I would like to improve my knowledge in java and I need help to make it happen1!
Best regards
Aina G
Aina G
Hi, Mr Lokesh, I did as you said to me, the error disappears but an another appears.
This is the error:
Invalid property ‘sessionFactory’ of bean class [org.springframework.orm.hibernate4.LocalSessionFactoryBean]: Bean property ‘sessionFactory’ is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
Can i have your e-mail, I would like to improve my knowledge in java and I need help to make it happen.!!
Best regards,

amarnath
First of all Thanks for the wonderful tutorial. I have successfully integrated Hibernate with Spring following your tutorial.
But I have one problem, I have included one more DTO that is UserDTO and mapped to USER table in my MYSQL and I have included it in the hibernate.cfg.xml file like below,
The problem is, it is working fine for the FeedbackDTO but for the UserDTO I am getting an exception as below,
HouseController:64 – ERROR: HouseController.verifyCredentials USER is not mapped [FROM USER]
I am unable to figure out, so please let me know how can I solve this.
Lokesh
Looks like posted code was lost. Please post the code in tags as suggested above comment box.
amarnath
I am able to solve it .. I made a mistake in the Query.
Query query = session.createQuery(“FROM User”); // Here I am using Db-table name instead of that I have to use the DTO name which I have mapped with the DB-Table;
Query query = session.createQuery(“FROM UserDTO”);
Lokesh
This is the best thing happened. I really like when somebody solves his problem in his own way.
ravi
hi lokesh
am getting
org.apache.jasper.JasperException: javax.servlet.ServletException: java.lang.StackOverflowError
this error and am not using maven dependency
solution
….
Lokesh
It may happen if your hibernate entities refer to each other such that they create a loop. Check for relationships between hibernate entities.
Wilfredo G.
Hi Lokesh, How can I get contact with you. I have a project that I need some help with. It is a Spring Hibernate project.
Thanks

Hi, i did the first steps but when i imported the project i received this error:
Faceted Project Problem (Java Version Mismatch)
How i can do to solve this problem?
Lokesh
Define the minimum and max JDK version in last of pom.xml like this.
<build> <finalName>name</finalName> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>2.3.2</version> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> </plugins> </build>anil
hi Lokesh, need to know few things i want project structure in maven like src/main/java, src/test/java, src/test/resources which archtype i need to use? give me the detailed explanation how to create this type of project structure
Lokesh
You should be using maven-archetype-webapp or maven-archetype-quickstart, depends on nature of java project i.e. webapp or normal java app.
More info is listed here:
https://maven.apache.org/archetypes/maven-archetype-quickstart/
https://maven.apache.org/plugins-archives/maven-archetype-plugin-1.0-alpha-7/examples/webapp.html
ravindhar
Hi lokesh actually the spring with hibernate directory structure is zig zag i will more elaborate means that musch of complexity having not understand easily understanding
Lokesh
Having hard time in understanding the comment.. 🙁
anil
did it by integrating with maven-plugin lokesh….can u post the same example by using Jquery…i want to know how it can be integrated….
Binh Tran
Hi Lockesh,
Would it be best if we don’t mix Spring DI with Hibernate in DAO layer? so we can have total separation between Data and Service Layers?.
1. Remove Hibernate related Configuration from Spring Bean and put them on backend Data layer
2. Only Use EmployeeDAO in Spring Bean configuration and AutoWire to EmployeeManager (service layer)
Please Advice.
Thanks Binh.
Lokesh
Hi Binh, Can you please elaborate more on “Remove Hibernate related Configuration from Spring Bean and put them on backend Data layer”? What exactly you want to do and it’s benefits?
Binh Tran
Hi Lokesh,
What I meant is to decouple Hibernate from Spring. The benefit is to remove coupling and having separation of layers. Please let me know if it is a good idea?
Thanks.
Lokesh
Decoupling in any form is always welcome in my view. Here I really have to think hard of a good way to decouple hibernate from spring completely. I will do my research. If you got any good suggestion, the please share it with all.
prem
Hi lokesh,nice Example..but how to do validations for the fields i.e when they don’t enter any fields.
riya
Hi Lokesh, I have few queries in integration of spring and hibernate. I need your email id. Please reply back to this message.
Sandeep
Hi Lokesh, i got good knowledge ..it is very useful for me…. one more thing instead of using sessionFactory we can use Hibernate Template class… we can reduce the code.. i think so no need of separate hibernate configuration file.. we can directly injected to AnnotatedSessionFactory ..
Lokesh
Good Points. May be I should write another post with above suggestions.
bernard
Thank-you so much for the work done
Mohan
Hi Lokesh,
index.jsp (welcomefile) is not calling here.could you clarify it?why is it ignoring here?
Surendra
public List getAllEmployees() {
return this.sessionFactory.getCurrentSession().createQuery(“from EmployeeEntity”).list();
}
EmployeeEntity created well and used for , but there is compile time error say “EmployeeEntity” can’t resolved the symbol….
see also in stackoverflow https://stackoverflow.com/questions/22606636/spring-hibernate-sql-entity-name-not-resolved
Surendra
Sorry that was behavior of Intellij IDE…after adding hibernate support for the project…that error resolved…Thank you!!! your project successfully run…
Lokesh
Glad, you resolved it.
Vipin
public List getAllEmployees() {
return this.sessionFactory.getCurrentSession().createQuery(“from EmployeeEntity”).list();
}
this is not working for me ….
i had almost copied yours example….
Lokesh
What’s the problem you are facing. Any exception?
Lokesh
Use below code:
ApplicationContext ac = new ClassPathXmlApplicationContext(“net/core/example/app-context.xml”);
In maven src/main/java is directory structure and not included in class path. From next time, confirm the path in “classes” folber inside “target” folder.
Vipin
Hi Lokesh….
i m new to hibernate n facing a problem ….which is how to retrieved a single object from a database…
and also a list of objects from database…..
whenever i tried to retrieved a single employee object ..error is…. get or load is not valid without active transaction… i had gooogled a lot but unable to fix this problem…Also
Can we return a object after retrieving it in service layer from try n catch block..???
Lokesh
Can you please post your hibernate configuration code and code where you are getting this exception. First look suggest that you are opening the transaction after a get/load method call. I.e. load() method is called outside a transaction.

Hi Lokesh,
It’s really good sample to start with Spring and hibernate framework. I’m trying to follow the steps you have described, but i’m getting below warning message while executing the command “mvn eclipse:eclipse -Dwtpversion=2.0” at step 2:
[WARNING] Workspace defines a VM that does not contain a valid jre/lib/rt.jar: C:\Program Files\Java\jre7
What could be the reason for this warning message. Could you please assist me to over come this?
Thanks,

Hi Lokesh! This article was very helpful.Thank you so much!!!!!!! Day by day I am becoming your fan!!!!!!
Manisha Pandey
Hello wanna thank you for this amazing tutorial ….I ws successful in this but when I tried this with JSF instead of JSP i am getting exception
It will be realy kind of you if u culd help me with this and explain the same thing with JSF. Thank you again
Lokesh
Just make sure you got spring web module loaded in runtime:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${org.springframework.version}</version>
</dependency>
kalyan
really useful …thank u so much 🙂
Piyush Grover
Thanks Lokesh sir. Awesome post.
Andrew
Sad to say but this tutorial is so messy and waste of time. Missing lots of instructions, I set up totally fresh envirnoment and it generated me lots of erros. Right after importing fresh maven generated files into Eclipse. I do not want to point all the missing things because there is a lot of them but for example author doesnt says how to import project into Eclipse (this step already generated number of errors) Than creation of Java class and its’ location is not mentioned. For me it was just lost of time going through this mess. I would suggest author to test his tutorials on fresh envirnoment not on half configured, that would saved a log of time his readers. I went through few of Lynda.com tutorials and NEVER have any suprising error.
Lokesh
I am very sorry if this tutorial caused so much pain to you. But, believe me I got lots of positive feedback for this tutorial and many people configured it in their first attempt.
Though, I do not expect anybody to configure all above steps in first attempt because they are complex for many of us. But, even if you are able to execute it in an hour also with 4-5 problems, then also I would say it’s good for you. I call this learning by mistakes. It is much more important than able to execute the project in first attempt.
Just to mention, I have attached the whole sourcecode (which is 100% correctly configured and executable) for reference if somebody struck for long time.

nadhine
hello! thanks for the tutorial. I would like to know one thing … within your project has other things … login, logout, access denied, but the project goes only to “Employee Management” screen is ok? Or missing something here? If not how can I implement this elsewhere?
Sorry for my english GTranslate
Lokesh Gupta
It’s how it has been written. If you want to forward any other screen you can do so.
Mike
Lokesh,
I followed your tutorial and used the same design except I wanted to use Volleyball recruits instead of Employees so I had…
Volleyball (instead of Spring3HibernateIntegration)
Recruit (instead of EmployeeEntity)
RecruitDAO (instead of EmployeeDAO)
RecruitDAOImpl (instead of EmployeeDAOImpl)
so forth and so on….and I changed all the references accordingly in all the files.
Also, I am using Tomcat instead of JBoss.
However I keep getting this error when I try to launch the program inside of STS. (Yes I’m also using Spring Tool Suite).
Jan 06, 2014 9:48:13 AM org.springframework.web.servlet.DispatcherServlet noHandlerFound

Finally I looked on this application. I didn’t find any problem with code. I believe problem is with program structure because when I used the same code and dependency in separate project, code worked fine. Below are steps I followed:
1) Create new maven project: [I renamed the project to vollyballs]
D:Latest Setupeclipse_juno_workspacevollyballs>mvn archetype:generate -DgroupId=com.howtodoinjava -DartifactId=vollyballs-DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
2) Concert to eclipse supported project
cd vollyballsmvn eclipse:clean eclipse:eclipse -Dwtpversion=2.0
3) Import project into eclipse and copy files from your code
4) Execute command:
mvn eclipse:clean eclipse:eclipse -Dwtpversion=2.0to update dependencies5) Deploy the app in tomcat server. Application was good and running.
I have uploaded the working code here:

Hi sir, iam newbie to spring.Iam having a doubt related to beans sir.i read your tutorial regarding Autowired and it types.and practiced the spring hibernate integration example.
i want to call a method in the same bean then how i have to call sir.
like
public class XX
{
public String AA()
{
//Here i want to call BB() with out using new method is it possible sir ?
}
public String BB()
{
}
}
public class YY
{
@Autowired
private XX x;
then
x.AA();// will work sir
x.BB();//working
}
but in the same bean how to call iam confusing please help me sir
Lokesh Gupta
Not sure what exactly you are looking for? Which method call you want to make in which class in your code sample?
Venkata Sriram
Hi sir,i want to call method BB() from AA() sir.
Lokesh Gupta
For calling methods defined in same class, you don’t need to do anything. Basic java rule. Call it directly. OR I am not getting you properly?
Venkata Sriram
ok sir .Thanks for clarification sir.

Hi lokesh, could you help me regarding how to manage transaction in spring with hibernate, i used annonation @transactional on service method. but i want to use manually
Session session = sessionFactory.getCurrentSession();
TransactionManager tx = null;
try {
tx= session.beginTransaction();
…..
..
..
tx.commit();
} catch (Exception e) {
tx.rollback();
}
but it doesn’t working.
so please tell me how to use?
your site is good but how to post new thread or blog here..
thanks
Lokesh Gupta
What’s problem you are facing in above code? AND, I will recommend you to use annotations for controlling transactions. It is more manageable and reduce lots of code. I am planning to add a forum in this blog, so that problems like this can be discussed in detail there.

A M Bharath
Hello Lokesh,
A general question regarding the concept of DAO layer…I assume the DAO interface represents a blueprint of various CRUD operations that can be performed on a Datasource (any datasource in fact) and each DAOImpl class refers to a specific Datasource (like MySQLDaoImpl, MongoDBDaoImpl etc) right? If this is the case, how to fit in some operational semantics that vastly differ from one Datasource to the another for the same kind of operation?
Eg:
public Object save(Object obj) -> let us say this applies to an insert operation using Hibernate for a MySQL datasource
public void save(Entity entity) -> let us say this applies to the same operation (insert) using some other JPA-based ORM for a NoSQL-type datasource like Cassandra/MongoDB
Please note that Entity, in the aforementioned, is the JPA-standard Annotation type.
In this case, how do we go about designing the interface and/or implementation classes of the DAO layer?
Sincerely,
A M Bharath
Lokesh Gupta
Bharath, It is a good question. My understanding is that we should not use Entity or any such class extensions out of DAO layer. We should use VO (Value objects) or TEO (Transfer Entity Object) which have almost similar fields/getters,setters/structure as Entity.
These VOs however can be used as model at view layer. And they will be present at controller and service layer, but not at DAO layer.
e.g. public EmployeeVO save(EmployeeVO employee);
Above declaration will completely de-couple the DAO layer from service layer because it does not care what you do in DAOImpl with EmployeeVO object, It just want that employee information saved somehow. Similarly other DAO methods will not accept/return any entity type thing. They will return only void/common java types or VO objects. They just need to copy the values from VO objects to DB specific objects and use them afterward. Similarily, after fetching data, they need to copy information in VO objects and return it.
In future, if you want to move from from hibernate to MongoDB, you will have to change only DAOImpl classes.
Am I missing anything???
A M Bharath
Perfect! 🙂 I now understand what it means to truly decouple the DAO layer from the others…you cleared my question to the fullest! Thanks!!
Sincerely,
A M Bharath
Akram
Thank you Gupta,

Hi Lokesh,
In the EMPLOYEE table, there is a column, “CREATED TIMESTAMP DEFAULT NOW()” but the EmployeeEntity class doesn’t seem to have a property representing this. Can you please explain how this column is getting updated upon the execution of the addEmployee(…) method?
Also, I’ve seen some posts in StackOverflow where there are recommendations to use JPA annotations like @PrePersist, @PostPersist etc to update TIMESTAMP columns (like CREATED, LAST_UPDATED etc). It has also been mentioned that Hibernate doesn’t support these annotations by default and that some listeners have to be used. Do you have any inputs in this regard?
Lokesh Gupta
I have used “DEFAULT NOW()” in DB schema for table which causes to store current timestamp everytime a new record is added.
@PrePersist, @PostPersist are new to me. I will learn more on them, and share my views.
A M Bharath
Hello Lokesh,
Thanks for your reply – in effect, you wrote the timestamp logic in your DB itself! Good idea there!
I was looking up some information on @PrePersist and @PostPersist etc. These are pure-JPA annotations and can’t be used with Hibernate’s SessionFactory. The work-around is to use either an interceptor https://dzone.com/articles/using-a-hibernate-interceptor-) OR an event-listener http://leakfromjavaheap.blogspot.com/2013/08/prepersist-and-preupdate-not-working.html & https://timezra.blogspot.com/2011/10/jpa-callbacks-with-hibernate.html
Do have a look at these since I’m sure these will make better sense to you than the newbie in me! 🙂
Thanks,
A M Bharath
A M Bharath
Hello Lokesh,
Another question on the same lines:
– If there has to be another database column called “updated” [that represents the last “updated” time stamp – i.e., when an update query is executed in the DAO layer for an “edit employee information” functionality in the application], how would you achieve it?
Thanks,
A M Bharath

I will give preference to this solution:

3) Deploy the application on server

Make sure you have defined @ModelAttribute(value=”employee”) in controller. Please refer to code above. Its working and tested in tomcat.
Pradeep
I tried out this sample and it works great. However I have some doubts to solve my specific issue:
1. In the EmployeeDTO object has a object like Address which is say a different class, how do we create the
form since the form contains only one commandName.
2. Second, Can we make the controller class accept json request also. How?
Please let me know the solutions for the above two. Your help is greaty appriciated.
Regards,
Pradeep
Lokesh Gupta
1) You can pass HashMap to view. In this way, you can send multiple different objects (not associated together) within single command object.
Another way is to wrap all data in a class, let’s say, EmployeeAddressVO and set all data in this class and pass to view layer.
2) Absolutely. Use headers=”Accept=application/json;” is request mapping. A working example with XML: https://howtodoinjava.com/spring/spring-restful/how-to-write-restful-webservices-using-spring-3-mvc/
Pradeep
I am planning to go with the first approach. Regarding your first reply: How can I populate the hashmap object and send it to the view? Also how to access the hashmap inside the jsp. Could you please eloborate?

Sorry buddy, can’t help with only this much information. May be you can upload your project to google docs and provide a link here. Then only somebody can help you.

Thanks. Though been new to the Spring world I think I have not gained my hands around some thing. Please can you prepare a war file of this so that I can just deploy it directly? Possibly it may the way I’m handling it that made me not get it. a war file for a beginner like me will be a very good start. Thanks.

hi lokesh,

do you have clue??
anmol

have you solved the problem?
please help me.
Alonso Isidoro Roman
thanks for sharing. I have learned that is possible to redirect to the same page using return “redirect:/”; but i have a question, if you are redirecting to / over any invocation controller methods, you are creating a new EmployeeEntity() and inserting over the map, even if it is not necessary, dont you think? Please share with us what you think.
otherwise, forgive my poor english, i am spaniard.
ken4ward
Thank you, Gupta. I have been on this for a while and it seems I am not yet getting somethings right because anytime I try to run the code, it generates this in the log file and it show 404 error, what should I do? Thanks.

Can you please list down the steps, you have done till now?
Have you downloaded the source code, or integrating of your own?
ken4ward
I downloaded the source code but implemented it on my own, not importing the code into Eclipse.
1. I downloaded the source code.
2. Created a web application project in Eclipse with the same name.
3. Created the application structure as it is indicated here.
4. Opened the pom.xml file and manually added the dependencies into the lib folder of the app.
5. Went to app Build path, go to the directory of the project and copied all the dependencies into the path as external jars.
6. Created files and just copy and pasted the codes from the forum here. Everything compiled fine, only the employee-servlet.xml flags a warning that javax.servlet is not found.
7. Deployed the application to Tomcat7.
Please I do not want to use Maven, it create a new learning curve for me, just want to try it out with webapps. The response is :”404 error”. Please help. Thanks.
Lokesh Gupta
I will suggest you to import first the downloaded sourcecode in some other application (with different name) and add all JAR dependencies you are using in existing project. Try to make it work first.
Once this application is successfully deployed and running, then you move code piece by piece into your new project.
ken4ward
Ok. Thanks. But what I’m trying to avoid is maven because I have tried with little success in configuring it. Please, if possible do you have a sample of this that is not implement Maven?
Lokesh Gupta
You can refer https://howtodoinjava.com/maven/ for maven installation and other simple tutorials. They are real easy.
Ajay
i am not able to download this project…Please can you mention the complete link..So in Just one shot i can download rar file..
Thanks,
Ajay
Lokesh Gupta
Use link in file menu : File >> Download
It will download the whole project
siddharth
where file? where download? i cant find these two… please explain from a-z how to download these application in a single shot ..
Thanks ,
Siddharth
Lokesh Gupta
Look at the bottom of post: “Download source code”. Its a link in bold. Click on that and proceed to download.
Siddharth
Yes i got it ….Thank you so much for explanation…
Ajay
Yes, i am able to do it…Thanks for nice explanation…
dharmendra
I reached this blog searching for annotation based Spring 3 and Hibernate 4 application in the hope that I will get rid of the xml configurations. But sadly this was not what I was looking for. Moreover, no where I found any tutorial for the same. Hence I wrote one. Putting a link here to benefit the users who might come here for what I was looking for.
To the admin: Please feel free to delete my comment and link if you think it to be offending.
Lokesh Gupta
Annotation based configuration is not the topic in this post, so it is not here naturally.
Brijesh
Thanks for sharing
Brijesh
Wonderful post. Thanks for your effort.
kaushal pandya
Yes , I am able to see the follwoing msg , but do;nt know why not working in CMD.
Browsing for this directory has been disabled.
View this directory’s contents on https://search.maven.org/ instead.
Lokesh Gupta
Your problem seems to be related to proxy which are normally configured in browsers, but not for CMD. Follow these instruction in given post to configure proxy settings for maven.
https://howtodoinjava.com/maven/maven-proxy-settings/
Kaushal Pandya
When i am running first command I am getting follwing issue, please suggest
Connection to http://repo.maven.apache.org refused
Lokesh Gupta
Are you able to access this URL from browser. Do you get any access denied error in browser?
Kaushal Pandya
Yes I am able to acces it .
JOO
i downloaded your source and imported it.
and i launched the application(http://localhost:8080/Spring3HibernateIntegration/) but it doesn’t work.
404 error message appeared
i am using tomcat
tell me anything how can i fix it T.T
Lokesh Gupta
Probably you have not setup the database. Check for tomcat console logs for deployment errors.
anil
sorry its a spelling mistake from my side…its working very fine..thanks for ur tutorial
Lokesh Gupta
Glad, you made it !!
anil
and 1 more thing i want to bring to ur notice is the records are not storing in db. when we restart the server the records which are inserted previously is not in db at all…. can u tell me whats the solution for it. as i need to write junit test cases the records has to be in db otherwise it will not pass.
Lokesh Gupta
Try settingupdate in
anil
ya its working fine now…i tried as u mentioned u above. prior to that i made an entry in employee-servlet.xml. as true even after autocommiting the records are not storing in db.. and at last i made a post to u.. thanks for ur advise
anil
tell me the url to launch the application
Lokesh Gupta
Its http://localhost:8080/Spring3HibernateIntegration/
Welcome file is configured as index.jsp in web.xml. So no need to type any relative URL.
anil
i did the same…i am using weblogic i typed http://localhost:9090/Spring3HibernateIntegration/ where i changed my port number to 9090
narendra
i am getting the below error while i run the application.
Lokesh Gupta
I does not look like programmatic error. Something is missing on runtime in DB.
Cyril
You have to create sequence for you table in the database.
