1、pom.xml引用active相关包

<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-all</artifactId>
    <version>5.15.8</version>
</dependency>

2、编写生产者代码

package com.du.jms.queue;
import org.apache.activemq.ActiveMQConnectionFactory;
import javax.jms.*;
/**
 * 消息的提供者
 * Created by only-dream on 2019/3/8 19:21
 */
public class AppProducer {

    private static final String url = "tcp://127.0.0.1:61616";
    private static final String queueName = "queue-test";//队列名称

    public static void main(String[] args) throws JMSException {
        //1.创建连接工厂
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
        //2.创建了连接
        Connection connection = connectionFactory.createConnection();
        //3.启动连接
        connection.start();
        //4.创建会话
        /* (第一个参数表示是否在事务中处理，一般为true)
         第二个参数表示印打模式，选用的自动印打*/
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //5.创建目标
        Destination destination = session.createQueue(queueName);
        //6.创建消息的生产者
        MessageProducer messageProducer = session.createProducer(destination);
        //7创建and发送消息
        for (int i = 0; i < 100; i++) {
            TextMessage textMessage = session.createTextMessage("test" + i);
            messageProducer.send(textMessage);
            System.out.println("消息发送成功"+textMessage);
        }
        //8.关闭连接
        connection.close();
    }
}

3、编写消费者代码(队列模式)

package com.du.jms.queue;
import org.apache.activemq.ActiveMQConnectionFactory;
import javax.jms.*;
/**
 * Created by only-dream on 2019/3/8 20:24
 */
public class AppConsumer {
    private static final String url = "tcp://127.0.0.1:61616";
    private static final String queueName = "queue-test";//队列名称

    public static void main(String[] args) throws JMSException {
        //1.创建连接工厂
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
        //2.创建了连接
        Connection connection = connectionFactory.createConnection();
        //3.启动连接
        connection.start();
        //4.创建会话
        /* (第一个参数表示是否在事务中处理，一般为true)
         第二个参数表示印打模式，选用的自动印打*/
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        //5.创建目标
        Destination destination = session.createQueue(queueName);
        //6.创建消息的消费者
        MessageConsumer consumer = session.createConsumer(destination);
        //7.创建一个监听器(监听是异步的，需要在监听到消息后再关闭连接)
        consumer.setMessageListener(new MessageListener() {
            public void onMessage(Message message) {
                TextMessage textMessage = (TextMessage) message;
                try {
                    System.out.println("接收消息"+textMessage.getText());
                } catch (JMSException e) {
                    e.printStackTrace();
                }
            }
        });
        //8.关闭连接
       // connection.close();
    }
}

4、主题模式创建的接收消息的时候只需把

Destination destination = session.createQueue(queueName);

改为

Destination destination = session.createTopic(topicName);

两者的区别是 
　　1.队列消息是平均分配消息，主题消息是获取所有的消息

   2.主题消息消费者不能获取未接收之前发布的消息
