2.该版本不是最新版本，最新版本启动报错，原因未知，所以用过的是：5.12版本

3.将文件解压：运行

4.登录服务器：http://localhost:8161/admin/index.jsp，默认用户名、密码为：admin

5.启动成功

6.编写消息生产者

package com.xuzhiwen.test;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnectionFactory;

public class SendMessage {
    public static String url = "tcp://localhost:61616";
    public static String queueName = "queue1";
    
    public static void main(String[] args) throws JMSException {
        ConnectionFactory connectionFactory = null;
        Connection connection = null;
        Session session = null;
        Destination destination = null;
        MessageProducer messageProducer = null;
        
        connectionFactory = new ActiveMQConnectionFactory(url);
        connection = connectionFactory.createConnection();
        connection.start();
        
        session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);
        
        destination = session.createQueue(queueName);
        messageProducer = session.createProducer(destination);
        
        for (int i = 0; i < 100; i++) {
            TextMessage tm = session.createTextMessage("生产者发送消息"+i);
            messageProducer.send(tm);
            System.out.println("【"+queueName+"】"+tm.getText());
        }
        connection.close();
    }

7.运行后结果如下：

9.编写消费者：

package com.xuzhiwen.test;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageConsumer;
import javax.jms.MessageListener;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnectionFactory;

public class GetMessage {
    public static String url = "tcp://localhost:61616";
    public static String queueName = "queue1";
    
    public static void main(String[] args) throws JMSException {
        ConnectionFactory connectionFactory = null;
        Connection connection = null;
        Session session = null;
        Destination destination = null;
        MessageConsumer messageConsumer = null;
        
        connectionFactory = new ActiveMQConnectionFactory(url);
        connection = connectionFactory.createConnection();
        connection.start();
        
        session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);
        
        destination = session.createQueue(queueName);
        messageConsumer = session.createConsumer(destination);
        
        messageConsumer.setMessageListener(new MessageListener() {
            
            @Override
            public void onMessage(Message msg) {
                TextMessage tm = (TextMessage) msg;
                try {
                    System.out.println(tm.getText());
                } catch (JMSException e) {
                    e.printStackTrace();
                }
            }
        });
    }
}
