2.生产者

package com.hourui.activemq;

import org.apache.activemq.ActiveMQConnectionFactory;

import javax.jms.*;

public class JmsProduce {

    public static final String ACTIVEMQ_URL = "tcp://192.168.61.100:61616";
    public static final String QUEUE_NAME = "queue01";


    public static void main(String[ ] args) throws JMSException {
        //1 创建连接工厂，按照给定的url地址，采用默认用户名和密码
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(ACTIVEMQ_URL);
        //2 通过连接工厂，获取连接connection 并启动访问
        Connection connection = activeMQConnectionFactory.createConnection();
        connection.start();

        //3 创建会话session
        //两个参数，第一个叫事务/第二个叫签收
        Session session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE);
        //4 创建目的地(具体是队列还是主题topic)
        Queue queue = session.createQueue(QUEUE_NAME);
        //5 创建消息的生产者
        MessageProducer messageProducer = session.createProducer(queue);
        //6 通过使用messageProducer生产3条信息发送到MQ的队列里面
        for(int i = 1; i <= 6; i++) {
            //7 创建消息，好比学生按照老师要求写好的面试题消息
            TextMessage textMessage = session.createTextMessage("msg---" + i);
            //8 通过messageProducer发送给mq
            messageProducer.send(textMessage);
        }
        //9 关闭资源
        messageProducer.close();
        session.close();
        connection.close();
        System.out.println("*********消息发布到MQ完成");

    }
}

3.消费者

    public static void main(String[ ] args) throws JMSException {

        System.out.println("我是1号消费者");
        //1 创建连接工厂，按照给定的url地址，采用默认用户名和密码
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(ACTIVEMQ_URL);
        //2 通过连接工厂，获取连接connection 并启动访问
        Connection connection = activeMQConnectionFactory.createConnection();
        connection.start();

        //3 创建会话session
        //两个参数，第一个叫事务/第二个叫签收
        Session session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE);
        //4 创建目的地(具体是队列还是主题topic)
        Queue queue = session.createQueue(QUEUE_NAME);
        //5 创建消费者
        MessageConsumer messageConsumer = session.createConsumer(queue);
        while (true) {
            TextMessage textMessage = (TextMessage)messageConsumer.receive();
            //TextMessage textMessage = (TextMessage)messageConsumer.receive(4000L);
            if(null != textMessage) {
                System.out.println("消费者接收到消息"+textMessage.getText());
            } else {
                break;
            }
        }
        messageConsumer.close();
        session.close();
        connection.close();
        System.out.println("*********消息发布到MQ完成");

    }
