Java Messaging Service (JMS) is all about applications communicating 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. Let’s get started.

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.
