activemq queue mode (II)

Create a maven project (quick to)

<! - add activemq dependence ->
    <dependency>
      <groupId>org.apache.activemq</groupId>
      <artifactId>activemq-all</artifactId>
      <version>5.9.0</version>
    </dependency>

 Creating Manufacturer:

package com.test.producermq;

import org.apache.activemq.*;

import javax.jms.*;

/**
 * @Title: MessageProducer
 * @ProjectName activemq
 * @date 2019/11/89:49
 */
public class MessageProducer {
    // define the connection address ActivMQ
    private static final String ACTIVEMQ_URL = "tcp://127.0.0.1:61616";
    // send message queue name is defined
    private static final String QUEUE_NAME = "MyMessage";

    public static void main(String[] args) throws JMSException {
        // 1. Create a connection factory
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(ACTIVEMQ_URL);
        // 2. Create a connection
        Connection connection = activeMQConnectionFactory.createConnection();
        3. // open connection
        connection.start();
        // 4. Create Session
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        // 5. Create a queue destination
        Destination destination = session.createQueue(QUEUE_NAME);
        // 6. Create a Producer
        javax.jms.MessageProducer producer = session.createProducer(destination);
        // create a simulated 100 messages
        for (int i = 1 ; i <= 100 ; i++){
            TextMessage message = session.createTextMessage("我发送message:" + i);
            //Send a message
            producer.send(message);
            // prints the message local
            System.out.println ( "I send a message is:" + message.getText ());
        }
        // close the connection
        connection.close();
    }
}

 

After running can be seen:

 

 

 Creating consumer:

package com.test.consumemq;

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

/**
 * @Title: MessageConsumer
 * @ProjectName activemq
 * @date 2019/11/89:56
 */
public class MessageConsumer {
    // define the connection address ActivMQ
    private static final String ACTIVEMQ_URL = "tcp://127.0.0.1:61616";
    // send message queue name is defined
    private static final String QUEUE_NAME = "MyMessage";
    public static void main(String[] args) throws JMSException {
        // 1. Create a connection factory
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(ACTIVEMQ_URL);
        // 2. Create a connection
        Connection connection = activeMQConnectionFactory.createConnection();
        3. // open connection
        connection.start();
        // 4. Create Session
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        // 5. Create a queue destination
        Destination destination = session.createQueue(QUEUE_NAME);
        // 6. Create a consumer
        javax.jms.MessageConsumer consumer = session.createConsumer(destination);
        // 7. Creating consumer monitor
        consumer.setMessageListener(new MessageListener() {
            @Override
            public void onMessage(Message message) {
                TextMessage textMessage = (TextMessage) message;
                try {
                    System.out.println ( "Get Message:" + textMessage.getText ());
                } catch (JMSException e) {
                    e.printStackTrace ();
                }
            }
        });
    }
}

　After running can be seen:

 

  Message has been consumed

Message Queue mode, and it is only being used by a consumer, and will not be shared
