ActiveMQ 入门例子

一：新建Maven项目，加入如下依赖

<dependency>
	<groupId>org.apache.activemq</groupId>
	<artifactId>activemq-all</artifactId>
	<version>5.11.1</version>
</dependency>

二：

server

package com.lala.mq;

import java.util.concurrent.TimeUnit;

import org.apache.activemq.broker.BrokerService;

public class Server
{
	public static void main(String[] args)throws Exception
	{
		BrokerService broker = new BrokerService();
		broker.addConnector("tcp://127.0.0.1:55551");
		broker.setUseJmx(false);
		broker.start();
		TimeUnit.SECONDS.sleep(9999);
	}
}

Producer

package com.lala.mq;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.MessageProducer;
import javax.jms.Queue;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnectionFactory;

public class MyProducer
{
	public static void main(String[] args) throws Exception
	{
		ConnectionFactory cf = new ActiveMQConnectionFactory("tcp://127.0.0.1:55551");

		Connection conn = cf.createConnection();

		conn.start();

		Session session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);

		Queue queue = session.createQueue("cib");

		MessageProducer producer = session.createProducer(queue);

		TextMessage tm = null;

		for(int i=1;i<=5;i++)
		{
			tm = session.createTextMessage("this is test message and msgid = " + i);
			producer.send(tm);
		}

		session.close();

		conn.close();
	}
}

Consumer

package com.lala.mq;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.MessageConsumer;
import javax.jms.Queue;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnectionFactory;

public class MyConsumer
{
	public static void main(String[] args)throws Exception
	{
		ConnectionFactory cf = new ActiveMQConnectionFactory("tcp://127.0.0.1:55551");

		Connection conn = cf.createConnection();

		conn.start();

		Session session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);

		Queue queue = session.createQueue("cib");

		MessageConsumer consumer = session.createConsumer(queue);

		consumer.setMessageListener((message) -> {
			TextMessage tm = (TextMessage)message;
			try {
				System.out.println("收到消息：" + tm.getText());
			} catch (Exception e) {
				e.printStackTrace();
			}
		});
	}
}

三：运行

先运行：Server

再运行：Consumer

最后运行：Producer

即可看到输出

最后

注意：以上做法不需要事先下载安装activemq服务
