Spring 3 Hornetq Standalone Integration Example

HornetQ is an open source project to build a multi-protocol, embeddable, very high performance, clustered, asynchronous messaging system. So far, we have learned about configuring hornetq standalone server and example of setting up basic messaging functionality. HornetQ comes with a lot of flexibility to be configured with some existing application frameworks. In this sequence, I am demonstrating the usage of HornetQ with Spring 3.

Lets do all the setup step by step.

Step 1) Create a maven project and convert it to eclipse java project.

Step 2) Update maven repository with spring 3 and hornetq dependencies.

</project>

Step 3) Add two additional jars in lib folder. If time permit you, find maven dependencies for them and add in pom.xml.

jnpserver-5.0.3.GA.jar
org.springframework.jms-3.0.5.RELEASE.jar

Step 4) Copy following files from jboss distribution and put in class path. Or, simply copy below files given here.

hornetq-configuration.xml

<configuration xmlns="urn:hornetq"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xsi:schemaLocation="urn:hornetq /schema/hornetq-configuration.xsd">

   <connectors>
      <connector name="netty">
         <factory-class>org.hornetq.integration.transports.netty.NettyConnectorFactory</factory-class>
         <param key="host"  value="${hornetq.remoting.netty.host:localhost}"/>
         <param key="port"  value="${hornetq.remoting.netty.port:5445}"/>
      </connector>
   </connectors>

   <acceptors>
      <acceptor name="netty">
         <factory-class>org.hornetq.integration.transports.netty.NettyAcceptorFactory</factory-class>
         <param key="host"  value="${hornetq.remoting.netty.host:localhost}"/>
         <param key="port"  value="${hornetq.remoting.netty.port:5445}"/>
      </acceptor>
   </acceptors>

   <security-settings>
      <security-setting match="#">
         <permission type="createTempQueue" roles="guest"/>
         <permission type="deleteTempQueue" roles="guest"/>
         <permission type="consume" roles="guest"/>
         <permission type="send" roles="guest"/>
      </security-setting>
   </security-settings>

   <address-settings>
      <!--default for catch all-->
      <address-setting match="#">
         <dead-letter-address>jms.queue.DLQ</dead-letter-address>
         <expiry-address>jms.queue.ExpiryQueue</expiry-address>
         <redelivery-delay>0</redelivery-delay>
         <max-size-bytes>-1</max-size-bytes>
         <page-size-bytes>10485760</page-size-bytes>         
         <message-counter-history-day-limit>10</message-counter-history-day-limit>
      </address-setting>
   </address-settings>

   <paging-directory>${hornetq.data.dir}/paging</paging-directory>
   <bindings-directory>${hornetq.data.dir}/bindings</bindings-directory>
   <journal-directory>${hornetq.data.dir}/journal</journal-directory>
   <large-messages-directory>${hornetq.data.dir}/large-messages</large-messages-directory>
</configuration>

hornetq-jms.xml

<configuration xmlns="urn:hornetq"
	       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	       xsi:schemaLocation="urn:hornetq /schema/hornetq-jms.xsd">
	
	<connection-factory name="NettyConnectionFactory">
	   <connectors>
         <connector-ref connector-name="netty"/>
	   </connectors>
		<entries>
			<entry name="/ConnectionFactory"/>
			<entry name="/XAConnectionFactory"/>
		</entries>
	</connection-factory>
	
	<queue name="ExampleQueue">
		<entry name="/queue/ExampleQueue"/>
	</queue>
	
	<topic name="ExampleTopic">
		<entry name="/topic/ExampleTopic"/>
	</topic>	
</configuration>

hornetq-users.xml

<configuration xmlns="urn:hornetq" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="urn:hornetq /schema/hornetq-users.xsd">
   <!-- the default user.  this is used where username is null-->
   <defaultuser name="guest" password="guest">
      <role name="guest"/>
   </defaultuser>
</configuration>

Step 5) Copy jndi.properties in classpath.

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

Step 6) Configure logger for better information capturing.

# Create a STDOUT appender
log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender
log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout
log4j.appender.STDOUT.layout.ConversionPattern=%05p | %m%n

# Default everything to WARN
log4j.rootCategory=WARN, STDOUT

# Enable this application log level to the lowest.
log4j.category.com.howtodoinjava=TRACE
log4j.category.org.jnp.server=INFO
log4j.category.org.hornetq=INFO
log4j.category.org.springframework=INFO

Step 7) So far, hornetq server and jndi has been configured. Now, plug them in spring framework in spring.xml and spring.properties.

spring.properties

hornetq.data.dir=${hornetq.spring.examples.home}/hornetq-data
org.hornetq.logger-delegate-factory-class-name=org.hornetq.integration.logging.Log4jLogDelegateFactory

Step 8) Lets load the spring container first. It will validate our all configurations files also.

SpringContainerLoader.java

package com.howtodoinjava.hornetq.demo;

import org.springframework.context.support.FileSystemXmlApplicationContext;

public class SpringContainerLoader
{
	public static FileSystemXmlApplicationContext loadEnvironment()
	{
		final FileSystemXmlApplicationContext context = new FileSystemXmlApplicationContext("classpath:config/server/spring.xml");
		context.registerShutdownHook();
		context.start();

		return context;
	}
}

Step 8) Now I will write the message producer and message consumer clients.

MessageProducerClient.java

package com.howtodoinjava.hornetq.demo;

import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.ProducerCallback;

public class MessageProducerClient implements Runnable {

	private static Log log = LogFactory.getLog(MessageProducerClient.class);

	private static int counter = 1;

	private JmsTemplate jmsTemplate;

	public void setJmsTemplate(JmsTemplate jmsTemplate) {
		this.jmsTemplate = jmsTemplate;
	}

	@Override
	public void run() {
		jmsTemplate.execute("ExampleQueue", new ProducerCallback<Object>() {
			@Override
			public Object doInJms(Session session, MessageProducer producer)
					throws JMSException {
				while (true) {
					TextMessage msg = session.createTextMessage("Message number : " + counter++);
					log.trace("Sending msg: " + msg);
					producer.send(msg);

					try {
						Thread.sleep(2000);
					} catch (InterruptedException e) {
						e.printStackTrace();
					}
				}
			}
		});

	}
}

MessageConsumerClient.java

package com.howtodoinjava.hornetq.demo;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageConsumer;
import javax.jms.Queue;
import javax.jms.Session;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.SessionCallback;

public class MessageConsumerClient implements Runnable {

	private static Log log = LogFactory.getLog(MessageConsumerClient.class);

	private JmsTemplate jmsTemplate;

	public void setJmsTemplate(JmsTemplate jmsTemplate) {
		this.jmsTemplate = jmsTemplate;
	}

	@Override
	public void run()
	{
		log.info("Message Consumer is just started !!");

		boolean startConn = true;
		jmsTemplate.execute(new SessionCallback<Object>() {
			@Override
			public Object doInJms(Session session) throws JMSException {
				Queue queue = session.createQueue("ExampleQueue");
				MessageConsumer consumer = session.createConsumer(queue);
				while (true) {
					Message msg = consumer.receive();
					log.trace("Received msg: " + msg);
				}
			}
		}, startConn);
	}
}

Step 9) Now its time to test the whole code and messaging functionality.

HornetQMessagingTest.java

package com.howtodoinjava.hornetq.demo;

import org.springframework.context.ApplicationContext;

public class HornetQMessagingTest
{
	public static void main(String[] args) throws InterruptedException
	{
		//Load configurations
		ApplicationContext context = SpringContainerLoader.loadEnvironment();

		//Start the message producer
		new Thread((Runnable)context.getBean("messageProducerClient")).start();

		//Start the message consumer
		new Thread((Runnable)context.getBean("messageConsumerClient")).start();

	}
}

Running above test class will produce below logs to verify the spring 3 and hornetq integration was successful.

In case any problem, please verify following things first:

All configurations files are in class path.
The two jar files present in lib folder are included in class path.

For reference purpose, I am giving a snapshot of directory structure.

Source code download

Happy Learning !!

Amol

which JAR has this class — org.hornetq.integration.transports.netty ??

John

I added spring-jms and I still can’t get it to compile. The following is undefined.

sampleJava/HornetQMessagingTest.java:10: cannot find symbol
symbol : variable SpringContainerLoader
location: class sampleJava.HornetQMessagingTest
ApplicationContext context = SpringContainerLoader.loadEnvironment();
^

Lokesh Gupta

John, it’s available in spring-context-.jar file. Please add the required dependencies and look for them in spring documentation.

Nisarg Panchal

You would need “spring-jms” lib in addition to existing dependencies. Nice post!

Prakash (@prakash32)
