1. Background information
We learned to integrate between Spring 3 and hibernate in linked post. That application was simple web application which presents a view where user can add/edit employees.
Lets secure that application. The scope of this tutorial is to:
- Only authorized user should be able to access edit employee screen.
- Unauthorized users should be presented with login screen.
- Successful credentials should forward to edit employee screen.
- Unsuccessful credentials should forward to access denied screen.
- There should be a link for logout of the application.
2. Spring security maven dependencies
Lets start with very first step i.e. update the project dependencies. It will add following four sub-modules in demo for following reasons:
- spring-security-core : It contains core authentication and access-control classes and interfaces.
- spring-security-web : It contains filters and related web-security infrastructure code. It also enable URL based security which we are going to use in this demo.
- spring-security-config : It contains the security namespace parsing code. You need it if you are using the Spring Security XML file for configuration.
- spring-security-taglibs : It provides basic support for accessing security information and applying security constraints in JSPs.
<properties>
<org.springframework.version>3.0.5.RELEASE</org.springframework.version>

Now use “mvn compile” command to update the dependencies in project.
3. Configure DelegatingFilterProxy in web.xml
Spring Security’s web infrastructure is based entirely on standard servlet filters. These filters are defined in web.xml file or they will be ignored by the servlet container.
In Spring Security, the filter classes are also Spring beans defined in the application context and thus able to take advantage of Spring’s rich dependency-injection facilities and lifecycle interfaces. Spring’s DelegatingFilterProxy provides the link between web.xml and the application context.
<filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
If you are not using any explicit filter definitions and wants spring to configure basic infrastructure for you, then use filter name as ‘springSecurityFilterChain‘ as in above example. Note that you should not use this bean name yourself. Once you’ve added this to your web.xml, you’re ready to start editing your spring security configuration file. Web security services are configured using the element.
Also do not forget to put security configuration file in context config location setting.
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/employee-servlet.xml
/WEB-INF/application-security.xml
</param-value>
</context-param>
A complete web.xml file will look like this:
<?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"

</web-app>
4. Configure login logout security
As we learned in last section that using filter name as springSecurityFilterChain can help you configure the basic infrastructure using element. Lets see how it is configured first? I have written a basic configuration for this demo:
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security-3.0.3.xsd">
<http auto-config="true" use-expressions="true">
<intercept-url pattern="/login" access="permitAll" />
<intercept-url pattern="/logout" access="permitAll" />
<intercept-url pattern="/accessdenied" access="permitAll" />
<intercept-url pattern="/**" access="hasRole('ROLE_USER')" />
<form-login login-page="/login" default-target-url="/list" authentication-failure-url="/accessdenied" />
<logout logout-success-url="/logout" />
</http>
<authentication-manager alias="authenticationManager">
<authentication-provider>
<user-service>
<user name="lokesh" password="password" authorities="ROLE_USER" />
</user-service>
</authentication-provider>
</authentication-manager>
</beans:beans>
Lets see what this configuration actually mean.
http: Include configuration related url level security. This element is the parent for all web-related namespace functionality.auto-config: Includes some basic services. It is shorthand for –<http> <form-login /> <http-basic /> <logout /> </http>use-expressions: It is here to use expressions to secure individual URLs. These expressions can be e.g.hasRole([role]),hasAnyRole([role1,role2]),permitAll,denyAlletc.intercept-url: This will match the requested url pattern from request and will decide what action to take based on access value.form-login: This will come into picture when user will try to access any secured URL. A login page mapped to “login-page” attribute will be served for authentication check. It is spring security login-processing-url.If not provided, spring will provide an inbuilt login page to user. It also contains attribute for default target if login success, or login failure due to invalid user/password match.
logout: This will help to find the next view if logout is called in application.
I am using XML based user service i.e. I will not go to database for password validation rather I have stored username/password combination in configuration file itself. To use this king of setup, authentication-manager is setup with inline in-built user details service. In more real time applications, this is going to be some user service fetching data from remote database.
5. Spring controller
I will reuse the controller and will add additional mappings and handler methods in controller. These additional URLs are /login, /logout and /accessdenied. The updated controller having all method handlers looks like this:
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 com.howtodoinjava.entity.EmployeeEntity;
import com.howtodoinjava.service.EmployeeManager;
@Controller
public class EditEmployeeController {
@Autowired
private EmployeeManager employeeManager;
public void setEmployeeManager(EmployeeManager employeeManager) {
this.employeeManager = employeeManager;
}
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login(ModelMap model) {
return "login";
}
@RequestMapping(value = "/accessdenied", method = RequestMethod.GET)
public String loginerror(ModelMap model) {
model.addAttribute("error", "true");
return "denied";
}
@RequestMapping(value = "/logout", method = RequestMethod.GET)
public String logout(ModelMap model) {
return "logout";
}
@RequestMapping(value = "/", method = RequestMethod.GET)
public String defaultPage(ModelMap map) {
return "redirect:/list";
}
@RequestMapping(value = "/list", 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:/list";
}
@RequestMapping("/delete/{employeeId}")
public String deleteEmplyee(@PathVariable("employeeId") Integer employeeId) {
employeeManager.deleteEmployee(employeeId);
return "redirect:/list";
}
}
6. Spring views
We have now configured our application with security configuration and controller handlers. Its time to write the views which are essentially JSP files. Most important addition in jsp files is login.jsp file.
This file have the form which contains text boxes for username and password field. Lets see how it is written:
6.1. login.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %> <%@ taglib uri="http://www.springframework.org/tags" prefix="spring" %> <html> <body> <h1 id="banner">Login to Security Demo</h1> <form name="f" action="<c:url value='j_spring_security_check'/>" method="POST"> <table> <tr> <td>Username:</td> <td><input type='text' name='j_username' /></td> </tr> <tr> <td>Password:</td> <td><input type='password' name='j_password'></td> </tr> <tr> <td colspan="2"> </td> </tr> <tr> <td colspan='2'><input name="submit" type="submit"> <input name="reset" type="reset"></td> </tr> </table> </form> </body> </html>
By default, spring auto generates and configures a UsernamePasswordAuthenticationFilter bean. This filter, by default, responds to the URL /j_spring_security_check when processing a login POST from your web-form. For username field it uses ‘j_username‘ and for password field it uses ‘j_password‘.
On submitting this form, UsernamePasswordAuthenticationFilter will match the username and password as configured in authentication-provider settings in application-security.xml.
6.2. logout.jsp
< % session.invalidate(); %> You are now logged out!! <a href="//howtodoinjava.com/spring/spring-security/login-form-based-spring-3-security-example/">go back</a>
This view simply invalidate the session and provide a link to go back to login page.
6.3. denied.jsp
This jsp file will come in user screen when user will try to authenticate with invalid user name and password combinations. It will show the corresponding message as configured in message.properties in your classpath.
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>
<body>
<h1 id="banner">Unauthorized Access !!</h1>
<hr />
<c:if test="${not empty error}">
<div style="color:red">
Your fake login attempt was bursted, dare again !!<br />
Caused : ${sessionScope["SPRING_SECURITY_LAST_EXCEPTION"].message}
</div>
</c:if>
<p class="message">Access denied!</p>
<a href="//howtodoinjava.com/spring/spring-security/login-form-based-spring-3-security-example/">Go back to login page</a>
</body>
</html>
7. Spring security login form demo
Its time to test the application. Simply deploy the application in any server e.g. in my case i am using Tomcat 7.0. Now, do following steps:
7.1. Type the URL in browser “http://localhost:8080/Spring3HibernateIntegration”
It will bring the login screen as besides /login, /logoutand /accessdenied all other URLs are protected URLs.
7.2. Try to authenticate with username ‘demo’ and password ‘1234’
It will given access denied error because username and password is invalid.
7.3. Try to authenticate with username ‘lokesh’ and password ‘password’
It will given employee management screen because username and password is correct.
7.4. Click on logout link
User will be logged out and login screen will appear.
I hope this spring mvc login example has been able to put some light on basic spring security mechanism using xml configurations. If you any question on this Spring security login form example, drop me a comment.
Happy Learning !!

Hi Lokesh,
Fine explanation. Great work. I want to know what is the use of ${sessionScope[“SPRING_SECURITY_LAST_EXCEPTION”].message} in denied.jsp page.
Lokesh Gupta
This link has all such constant values. Follow each constant link to read about them.
https://docs.spring.io/spring-security/site/apidocs/constant-values.html
e.g. If authentication fails, the resulting
AuthenticationExceptionwill be placed into theHttpSessionwith the attribute defined bySPRING_SECURITY_LAST_EXCEPTION_KEY.saurabh
Hi Lokesh,
this article is very helpful for beginers. Thanks for writing.

what is the Difference between Spring Security and Spring AOP .we can also provide security through AOP . which one is Reliable
Lokesh Gupta
Spring AOP and Security – both are entirely different things for different purposes. Yes, it’s possible to use AOP for some of security features. Regarding reliability, as I said both are different things and should not be compared.

HI LOKESH,
I WANT TO KNOW HOW TO USE INPUT VALIDATION IN THE FORM FIELDS IN JSP WITH THE HELP OF SPRING SECURITY FRAMEWORK.
Lokesh Gupta
Spring security is for server side, and that’s how it should be used. For only input validation, I suggest to use jQuery.
Though you can use it for other things in JSP : https://howtodoinjava.com/spring-security/spring-security-at-view-layer-using-jsp-taglibs/

I am using spring 3.2 and have included Spring security 3.2.6 Release jars in the classpath.
However when I try to use inbuilt login page, it seems to be working fine in case of valid and invalid credentials for the following configuration:

HI Lokes Thanks for your Example.
My question is when user add the employee button it will call the /add method of controller.Is this restricted by sequrity filter
or not.How to get which user is call the /add url.
please explain it.
Thanks in advance.
Lokesh
Right now application is secured only through login page. Once authenticated user can perform any action inside application. To add action specific security, use method level security.

Have you created “test” database with Employee table in it? Error is suggesting that you have not. Please verify.
In this application, you don’t need db access. Please share the modifications you did.

Well, I thank you for your sample website, but 90% of the spring websites out there use css, images, and js folders. Since the security namespace affects their access it becomes tricky to resolve. But I figured out what to do. In application-security.xml I had to add these 3 lines:
So I don’t say you Must put them, but it would be helpful if it was put.

Thanks for your contribution to this page and sharing your solution.

Sorry, I did not include the code properly.
Here it is:

Lokesh
Please post code inside [xml] … [/xml] tags.

Hi, I downloaded and ran this sample app successfully. However, after I added the security part into my existing “non-secure” Spring MVC project it screwed up with access to CSS and Images paths, so I can’t see CSS and Images on my pages. Here is my configuration for them:
And this is from my existing login.jsp:
….
So some conflict happened with the context, I guess. Do you know how to fix it? Thank you.

Yes you should have one local setup. OR create an in-memory database using info from here : https://howtodoinjava.com/hibernate/hibernate-4-using-in-memory-database-with-hibernate/

Thank you very much for the useful example. I have one question. Is there any possible to add the user in user_service at run time? if yes, how could we?
Lokesh
It is basically example with help of in-memory “authentication-provider”. If user’s list is going to increase the use any custom authentication provider.

I have a requirement to secure REST services with basic authentication and the web pages, when accessed by browser via Form based authentication.I am trying to combine both of them with Spring-Security-3.2..I read the docs and am trying to follow it , but am not able to configure the spring-context.xml properly..While deploying I get the following errors, Can anyone give me an example of the spring-context.xml.
Caused By: org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: No AuthenticationEntry Point could be established. Please make sure you have a login mechanism configured through the namespace (such as form-login) or s pecify a custom AuthenticationEntryPoint with the ‘entry-point-ref’ attribute Offending resource: class path resource [/security-context.xml] at org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:68) at org.springframework.beans.factory.parsing.ReaderContext.error(ReaderContext.java:85) at org.springframework.beans.factory.parsing.ReaderContext.error(ReaderContext.java:72) at org.springframework.security.config.http.AuthenticationConfigBuilder.selectEntryPoint(AuthenticationConfigBuilder.java: 520) at org.springframework.security.config.http.AuthenticationConfigBuilder.createExceptionTranslationFilter(AuthenticationCon figBuilder.java:416) Truncated. see log file for complete stacktrace >
Your help is very much appreciated

I do not have a handy example at this time and will plan to build one such in future. But, in my understanding, this should be done inside SecurityInterceptor. There you should try to find out whether client is java client or NBI (non-browser interface) client. Decision can be based on some parameters or simply request headers. Once client type is determined, handle it accordingly (e.g. for browser based check existing session etc).

Thanks for the tutorial! Is this tutorial Spring 4.0 compliant? Will any changes have to be made to use Spring 4.0.
Lokesh
I ma not sure but backward compatibility must have been preserved.

helpful example – /** did the trick for me in the security URL interception

Hi Lokesh
Nice post.
I have an existing web application build on Primefaces, EJB and without Spring. Will I be able to integrate spring security 3.2 to this existing application ?
Thanks
Jay
Lokesh
Definitely yes. Spring provides seamless integration with all major frameworks including primefaces. Go through some information listed here: https://www.google.co.in/search?q=Primefaces+with+spring+security

Hi sir,i wrote similar kind of security-context.xml file,iam getting the following error:
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element ‘http’.

Thanks

Make sure you have used correct namespace definitions:
beans:beans xmlns="http://www.springframework.org/schema/security"xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/security/
http://www.springframework.org/schema/security/spring-security-3.0.3.xsd“

Thanks for the tutorial. However i have a couple of queries. First one, on startup how is it getting redirected to the login page? Secondly,on page submission how does these ‘j_spring_security_logout’ or ‘j_spring_security_check’ work??
Lokesh Gupta
I mentioned it already: By default, spring auto generates and configures a UsernamePasswordAuthenticationFilter bean. This filter, by default, responds to the URL /j_spring_security_check when processing a login POST from your web-form. For username field it uses ‘j_username‘ and for password field it uses ‘j_password‘.

Reason seems to be that /WEB-INF/application-security.xml is not loaded at runtime. Make sure it is present in .war file (or target folder).

Great tutorial and it works perfect. However my doubt is won’t spring security support special characters in username? I need to use my email as username but it throws error…!!
Lokesh Gupta
Need to check
Karthi
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [java.empcontroller.EditEmployeeController] for bean with name ‘editEmployeeController’ defined in file [D:karthikaSpring Workspace.metadata.pluginsorg.eclipse.wst.server.coretmp0wtpwebappsSpringSecurityWebApplnWEB-INFclassesjavaempcontrollerEditEmployeeController.class]; nested exception is java.lang.ClassNotFoundException: java.empcontroller.EditEmployeeController
Lokesh Gupta
Exception is self explanatory. Class not found. Look into your classes folder if it is generated. By the way, having package name starting with “java”— I will not recommend this. This is used for JDK supplied classes. Compiler will not prevent you, but you really should not use this.

here where is the employee entity and employee manager classes
