Spring 4+JMS+ActiveMQ Example with Annotations

Java Messaging Service (JMS) is all about applications communication using standard based messaging. With JMS, applications communicates with each other by sending and receiving messages. Spring provides first-class support for application integration using JMS. In this tutorial series, we will explore various ways Spring helps us simplify the JMS integration by abstracting all the complexities and providing simple APIs for use in our applications for synchronous as well as asynchronous communication.

There are various JMS providers which implements JMS standard and provides additional implementaion-specific functionalities. Apache ActiveMQ , IBM Websphere MQ , JBoss hornetQ to name a few. We will focus on ActiveMQ in this tutorial.


Following technologies being used:

  • Spring 4.3.0.RELEASE
  • Spring JMS 4.3.0.RELEASE
  • ActiveMQ 5.13.3
  • Maven 3
  • JDK 1.7
  • Tomcat 8.0.21
  • Eclipse MARS.1 Release 4.5.1
  • logback 1.1.7

Before we jump into code, lets take a quick overview of basic JMS concepts.

Destination

Each JMS message sent by an application is addressed with a destination. Destinations in JMS are like postal mailboxes where the messages are placed until someone comes to pick them up. There are two types of destination in JMS: queues and topics.

  • Queues [point-to-point]: Queue’s are based on point-to-point messaging model where messages are sent to a queue. Each message has exactly one sender and one receiver. Message is guaranteed to be delivered to only one receiver.

  • Topics [publish-subscribe]:Topic’s are based on publish-subscribe model where messages are sent to a topic. N subscribers can be subscribed on a topic, and when a message arrives, each will get a copy of that message.

ConnectionFactory

In order to create a connection to a messaging provider [message broker], we need connection factories. ConnectionFacotry is basically administrative objects with configurations parameters.

Persistent/Non-persistent Messages [Aka Delivery Mode : for Messages]

Delivery Mode refers to persistence/non-persistence of messages which can be specified on MessageProducer level as well as on individual message level. Default delivery mode is PERSISTENT, means messages will be stored on disk/database until it is consumed by a consumer, and will survive a broker restart. When using non-persistent delivery, if you kill a broker then you will lose all in-transit messages.

Durable / Non-durable subscriptions[for Topics]

Subscription refers to subscription on a topic. With a durable subscription, if the subscriber [which has subscribed for message on a topic] is down for some time, once it comes up, it will receive all the messages sent for it(including the ones sent when it was down). With Non-durable subscription, a subscriber will receive only the messages when it was connected to topic (will loose all the ones sent when it was down). Note that this is not applicable for Queue’s as they can be considered always durable [only one consumer, and it will always receive the message destined for it in queue].

OK, enough with theory, lets get into practice. Firstly download ActiveMQ Message Broker, unzip it, goto bin directory and start it using $ ./activemq start.

You can quickly check the WebConsole [available at http://localhost:8161/admin/ with credentials admin/admin.

Application(s) Overview:

In our post, we have two applications A & B trying to communicate with each other via sending Messages on Queues. Although we could have opted for Topic instead, Queue is perfect for this one producer-one consumer scenario.

A sends a message [a pojo object] to a Queue [order-queue] and listens for the response on another Queue [order-response-queue]. B is listening on order-queue, and upon receiving the message, B will send a reply [a pojo response object] to A on order-response-queue. A short but simple example of inter-application communication using JMS.

Let’s start with coding Application A. Application B is exactly same as A, but listening and sending on opposite queues.

Step 1. Messaging Configuration using Spring & ActiveMQ

package com.websystique.spring.configuration;

import java.util.Arrays;

import javax.jms.ConnectionFactory;

import org.apache.activemq.spring.ActiveMQConnectionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jms.connection.CachingConnectionFactory;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.listener.DefaultMessageListenerContainer;
import org.springframework.jms.listener.MessageListenerContainer;
import org.springframework.jms.support.converter.MessageConverter;
import org.springframework.jms.support.converter.SimpleMessageConverter;

import com.websystique.spring.messaging.MessageReceiver;

@Configuration
public class MessagingConfiguration {

	private static final String DEFAULT_BROKER_URL = "tcp://localhost:61616";
	
	private static final String ORDER_QUEUE = "order-queue";
	private static final String ORDER_RESPONSE_QUEUE = "order-response-queue";
	
	@Autowired
	MessageReceiver messageReceiver;
	
	@Bean
	public ConnectionFactory connectionFactory(){
		ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
		connectionFactory.setBrokerURL(DEFAULT_BROKER_URL);
		connectionFactory.setTrustedPackages(Arrays.asList("com.websystique.spring"));
		return connectionFactory;
	}
	/*
	 * Optionally you can use cached connection factory if performance is a big concern.
	 */

	@Bean
	public ConnectionFactory cachingConnectionFactory(){
		CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
		connectionFactory.setTargetConnectionFactory(connectionFactory());
		connectionFactory.setSessionCacheSize(10);
		return connectionFactory;
	}
	
	/*
	 * Message listener container, used for invoking messageReceiver.onMessage on message reception.
	 */
	@Bean
	public MessageListenerContainer getContainer(){
		DefaultMessageListenerContainer container = new DefaultMessageListenerContainer();
		container.setConnectionFactory(connectionFactory());
		container.setDestinationName(ORDER_RESPONSE_QUEUE);
		container.setMessageListener(messageReceiver);
		return container;
	}

	/*
	 * Used for Sending Messages.
	 */
	@Bean 
	public JmsTemplate jmsTemplate(){
		JmsTemplate template = new JmsTemplate();
		template.setConnectionFactory(connectionFactory());
		template.setDefaultDestinationName(ORDER_QUEUE);
		return template;
	}
	
	
	@Bean 
	MessageConverter converter(){
		return new SimpleMessageConverter();
	}
	
}

ConnectionFactory: ActiveMQ provides a Spring based built-in implementation of JMS connection factory [javax.jms.ConnectionFactory] ActiveMQConnectionFactory, which provides possibilities for further configuration of connection factories. Optionally, if you need more performance, you can configure a CachingConnectionFactory which adds caching.

This connection factory(along with Destination) will be used by both Sender [using JmsTemplate] and receiver [using MessageListenerContainer].

Destination: Destinations needs to be configured for both sending and receiving ends. ActiveMQ comes up with builin implementations for Queue [ActiveMQQueue] and Topic [ActiveMQTopic]which can accept a String [QUEUE or Topic name] as an argument. Although we could use them, we have further simplified our configuration by directly configuring the destination-name on Sending [With JmsTemplate] and Receving [With Listener] side.

JmsTemplate : JmsTemplate provides an abstraction which hides all the complexities of JMS communication. Without JmsTemplate, you will be forced to create connections/sessions/MessageProducers/MessageConsumers and catch all the nasty exception platform may throw. With JmsTemplate ,you get simple API’s to work with , and spring behind-the-scenes take care of all the JMS complexities. It takes care of creating a connection, obtaining a session, and finally sending [as well as synchronous receiving] of message. We will be using JmsTemplate for sending the message. Do note that JmsTemplate also provides possibilities for receiving message but that is synchronous[blocks the listening application], and usually not preferred when asynchronous communication is possible.

MessageListenerContainer : MessageListenerContainer comes handy when we want to implement asynchronous message reception. It can be configured to use a bean [which implements javax.jms.MessageListener] whose onMessage() method will be called on message reception.

Below shown is the bean we have configured for asynchronous Message reception.

package com.websystique.spring.messaging;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.support.converter.MessageConverter;
import org.springframework.stereotype.Component;

import com.websystique.spring.model.InventoryResponse;

@Component
public class MessageReceiver implements MessageListener{

	static final Logger LOG = LoggerFactory.getLogger(MessageReceiver.class);
	
	@Autowired
	MessageConverter messageConverter;
	
	@Override
	public void onMessage(Message message) {
		try {
			LOG.info("+++++++++++++++++++++++++++++++++++++++++++++++++++++");
			InventoryResponse response = (InventoryResponse) messageConverter.fromMessage(message);
			LOG.info("Application : order response received : {}",response);	
			LOG.info("+++++++++++++++++++++++++++++++++++++++++++++++++++++");
		} catch (JMSException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}
}

Thanks to MessageListenerContainer, onMessage method of MessageReceiver bean will be called whenever there is a message on the queue [The Listener was listening to].

MessageConverter : Spring further helps us by providing converters which convert Java objects to JMS messages and viceversa.

We have seen the receiving side, let’s see how to send the Message now. JmsTemplate is all you need to send the messages. It comes with several methods[send*,convertAndSend*] to choose from while sending the messages.

package com.websystique.spring.messaging;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.ObjectMessage;
import javax.jms.Session;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Component;

import com.websystique.spring.model.Product;

@Component
public class MessageSender {

	@Autowired
	JmsTemplate jmsTemplate;

	public void sendMessage(final Product product) {

		jmsTemplate.send(new MessageCreator(){
				@Override
				public Message createMessage(Session session) throws JMSException{
					ObjectMessage objectMessage = session.createObjectMessage(product);
					return objectMessage;
				}
			});
	}

}

That’s all for Application A setup. Below shown is the Directory Structure for Project A.

SpringJMSEX1_img2
Now just flip the QUEUE’s and Application B is ready. Before we start both the applications and see message transfer in action, shown below is the directory structure and configuration code for Application B [Mirror image].

Start Application A [ProducerEx1]. Goto web-console, and click on queue tab. You should see two queues being created with a message on one queue [A has just sent a message] while other empty.

SpringJMSEX1_img4

Now start Application B [ConsumerEx1], again check queues on web-console, you will see message being de-queued on first queue [B has just processed it] and new message being enqueued [B has sent the response to A] and eventually dequeued [A got the response] on second queue.

That’s it. As we saw, SPRING JMS support is easy to use. Feel free to Comment, and suggest improvements.

  • mahatma gandhi

    Hi,

    I downloaded both of your projects and imported them into eclipse, Both imported without any errors.
    I added both to a tomcat v8 sever in eclipse and started the server.
    i can see that the server started up in the logs but nothing is happening. I cant see my queues in the broker web ui. i have also added a system.out line in the main method of one of the clients but it is not getting printed out. This probably means that something else is still not configured. Any ideas what that could be?

    Thanks

    • websystique

      Hi, Did you first started your Message broker [using ./activemq start. e.g.]?

      • mahatma gandhi

        Hi,

        Yes the message broker was started first and is accessible. Next I started the tomcat server from eclipse. Now from what I can see in the initial logs catalina started up but the two web apps didn’t. The reason I think this is that normally when I start a Spring app there is something in the logs about ‘Initializing Spring root WebApplicationContext’ or mapping handlers or some kind of output from spring.
        However there is the following warning in the logs:
        ‘WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property ‘source’ to ‘org.eclipse.jst.jee.server:SpringJMSActiveMQProducerEx1′ did not find a matching property.’

        Thanks

    Thanks for the post. It really helps for java annotation application.But when I am trying to run application getting issue as it is resulting in multiple connection factory for activemqconnectionfactory and cachingconnectionfactory. I have found solution for that by making one of that bean as annoted with @primary. So i annoted cachingconnectionfactory bean as @primary and it is working now.
