III. message producers
 

Peer to peer message producers
@Service
public class QueueProductService {
    @Autowired
    private JmsTemplate jmsQueueTemplate;

    //Use default destination
    public void sendMessageDefault(final String msg) {
        Destination destination = jmsQueueTemplate.getDefaultDestination();
        System.out.println("To the queue: " + destination + " Successfully sent a message");
        jmsQueueTemplate.send(new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage(msg);
            }
        });
    }

    //Destination can be specified
    public void sendMessage(Destination destination, final String msg) {
        jmsQueueTemplate.send(destination, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage(msg);
            }
        });
    }
}


//Publish / subscribe message producers
@Service
public class TopicProductService {
    @Autowired
    private JmsTemplate jmsTopicTemplate;

    //Use default destination
    public void sendMessageDefault(final String msg) {
        Destination destination = jmsTopicTemplate.getDefaultDestination();
        System.out.println("towards topic:  " + destination + " Successfully sent a message");
        jmsTopicTemplate.send(new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage(msg);
            }
        });
    }

    //Destination can be specified
    public void sendMessage(Destination destination, final String msg) {
        System.out.println(Thread.currentThread().getName() + " towards" + destination.toString()
                + "Send subject:" + msg);
        jmsTopicTemplate.send(destination, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage(msg);
            }
        });
    }
}


IV. message listener
 

public class QueueMessageListener implements MessageListener{

    @Override
    public void onMessage(Message message) {

        TextMessage tm = (TextMessage) message;
        try {
            System.out.println("Message received by listener 1-----"+tm.getText());
        } catch (JMSException e) {
            System.out.println("QueueMessageListener abnormal");
            e.printStackTrace();
        }

    }
}

QueueMessageListener2,QueueMessageListener3,QueueMessageListener4 Same as above


Five, test

@RequestMapping("/send")
@ResponseBody
public String sendMeg(){
System.out.println("send queue message");
    Destination destination=new ActiveMQQueue("order.queue");
    queueProductService.sendMessage(destination,"hello.queue");
    return "ok";
}

@RequestMapping("/send2")
@ResponseBody
public String sendMeg2(){
System.out.println("send topic message");
    Destination destination=new ActiveMQTopic("order.topic");
    topicProductService.sendMessage(destination,"hello.topic.123");
    return "ok";
}    

Note how to instantiate Destination:
Destination destination=new ActiveMQQueue("order.queue");
Destination destination=new ActiveMQTopic("order.topic");

Observe console output:
Send topic message
http-nio-8080-exec-5 send topic to topic://order.topic: hello.topic.123
Message received by listener 3 ------ hello.topic.123
Message received by listener 4 ------ hello.topic.123
Send queue message
Message received by listener 2 ------ hello.queue
Send queue message
Message received by listener 1 ------ hello.queue

It can be seen that:
The queue message will only be consumed randomly once, and the topic will be consumed twice
