1、引入依赖

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

2、queue模式

2.1、创建producer

package com.szl.jms.activemq.queue;

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;

/**
 * @author szl
 * @data 2018年8月5日 下午9:50:06
 *
 * 消息生产者
 */
public class MsgProducer {

	private static final String url ="tcp://127.0.0.1:61616";
	private static final String queueName ="activemq-queue";
	
	public static void main(String[] args) throws JMSException {
		//1、创建ConnectionFactory
		ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
		//2、创建Connection
		Connection connection = connectionFactory.createConnection();
		//3、启动连接
		connection.start();
		//4、创建会话  false:不使用事务处理，Session.AUTO_ACKNOWLEDGE自动应答
		Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
		//5、创建目标
		Destination destination = session.createQueue(queueName);
		//6、创建生产者
		MessageProducer producer = session.createProducer(destination);
		for (int i = 0; i < 100; i++) {
			//7、创建消息
			TextMessage textMessage = session.createTextMessage("queueTest " + i);
			//8、发布消息
			producer.send(textMessage);
			System.out.println("发送消息：" + textMessage.getText());
		}
		//9、关闭连接
		connection.close();
	}
}

2.2、创建consumer

package com.szl.jms.activemq.queue;

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.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnectionFactory;

/**
 * @author szl
 * @data 2018年8月5日 下午10:11:41
 *
 * 消息消费者
 */
public class MsgConsumer {

	private static final String url ="tcp://127.0.0.1:61616";
	private static final String queueName ="activemq-queue";
	
	public static void main(String[] args) throws JMSException {
		//1、创建ConnectionFactory
		ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
		//2、创建Connection
		Connection connection = connectionFactory.createConnection();
		//3、启动连接
		connection.start();
		//4、创建会话  false:不使用事务处理，Session.AUTO_ACKNOWLEDGE自动应答
		Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
		//5、创建目标
		Destination destination = session.createQueue(queueName);
		//6、创建消费者
		MessageConsumer consumer = session.createConsumer(destination);
		//7、创建监听器
		consumer.setMessageListener(new MessageListener() {
			@Override
			public void onMessage(Message message) {
				TextMessage textMessage = (TextMessage) message;
				try {
					System.out.println("接收消息：" + textMessage.getText());
				} catch (JMSException e) {
					e.printStackTrace();
				}
			}
		});
	}
}

2.3、运行

可以先启动Consumer或者先启动Producer，只要发送消息成功，就能接受到消息。运行多个Consumer，每个Consumer平均接收Producer发送的消息。可以在http://localhost:8161/admin/queues.jsp查看信息。

3、Topic模式

3.1、创建producer

package com.szl.jms.activemq.topic;

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;

/**
 * @author szl
 * @data 2018年8月5日 下午10:27:36
 *
 */
public class MsgProducer {

	private static final String url ="tcp://127.0.0.1:61616";
	private static final String topicName ="activemq-topic";
	
	public static void main(String[] args) throws JMSException {
		//1、创建ConnectionFactory
		ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
		//2、创建Connection
		Connection connection = connectionFactory.createConnection();
		//3、启动连接
		connection.start();
		//4、创建会话  false:不使用事务处理，Session.AUTO_ACKNOWLEDGE自动应答
		Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
		//5、创建目标
		Destination destination = session.createTopic(topicName);
		//6、创建生产者
		MessageProducer producer = session.createProducer(destination);
		for (int i = 0; i < 100; i++) {
			//7、创建消息
			TextMessage textMessage = session.createTextMessage("test " + i);
			//8、发布消息
			producer.send(textMessage);
			System.out.println("发送消息：" + textMessage.getText());
		}
		//9、关闭连接
		connection.close();
	}
}

1.2、创建Consumer

package com.szl.jms.activemq.topic;

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.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnectionFactory;

/**
 * @author szl
 * @data 2018年8月5日 下午10:27:24
 *
 */
public class MsgConsumer {

	private static final String url ="tcp://127.0.0.1:61616";
	private static final String topicName ="activemq-topic";
	
	public static void main(String[] args) throws JMSException {
		//1、创建ConnectionFactory
		ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
		//2、创建Connection
		Connection connection = connectionFactory.createConnection();
		//3、启动连接
		connection.start();
		//4、创建会话  false:不使用事务处理，Session.AUTO_ACKNOWLEDGE自动应答
		Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
		//5、创建目标
		Destination destination = session.createTopic(topicName);
		//6、创建消费者
		MessageConsumer consumer = session.createConsumer(destination);
		//7、创建监听器
		consumer.setMessageListener(new MessageListener() {
			@Override
			public void onMessage(Message message) {
				TextMessage textMessage = (TextMessage) message;
				try {
					System.out.println("接收消息：" + textMessage.getText());
				} catch (JMSException e) {
					e.printStackTrace();
				}
			}
		});
	}
}

2.3、运行

要先运行Consumer，再运行Producer，否则Consumer接收不到Producer发送的消息。启动多个Consumer，每个Consumer接收到全部的消息。可以在http://localhost:8161/admin/topic.jsp查看信息。
