ActiveMQ简易入门

ActiveMQ官方下载地址：http://activemq.apache.org/download.html

下载解压后，执行bin目录下activemq.bat启动mq服务

找到lib目录并引入相关jar包

Sender消息发送者类

package com.ycj.activemq;import javax.jms.Connection;import javax.jms.ConnectionFactory;import javax.jms.DeliveryMode;import javax.jms.Destination;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.MessageProducer;import javax.jms.Session;import org.apache.activemq.ActiveMQConnectionFactory;public class Sender {    private static final String MQ_USER = "admin";        private static final String MQ_PWD = "admin";        private static final String MQ_URL = "tcp://localhost:61616";        private static final String MQ_QUEUE_DEFAULT = "testQueue";                public static void main(String[] args) throws JMSException {                // 创建JMS连接工厂                ConnectionFactory factory = new ActiveMQConnectionFactory(MQ_USER, MQ_PWD, MQ_URL);                // 通过工厂获取链接并启动                Connection connection = factory.createConnection();                connection.start();                // 创建session                Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);                // 创建destination 消息目的地                Destination destination = session.createQueue(MQ_QUEUE_DEFAULT);                // 根据destination初始化一个生产者                MessageProducer producer = session.createProducer(destination);                // 生产者消息不持久化            producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);            // 生成消息 并发送            Message msg1 = session.createTextMessage("I'm msg1");            Message msg2 = session.createTextMessage("I'm msg2");            producer.send(msg1);            producer.send(msg2);            session.commit();            connection.close();            System.out.println("producer send msg done!");        }}

Receiver消息接收者类

package com.ycj.activemq;import javax.jms.Connection;import javax.jms.ConnectionFactory;import javax.jms.Destination;import javax.jms.JMSException;import javax.jms.MessageConsumer;import javax.jms.Session;import javax.jms.TextMessage;import org.apache.activemq.ActiveMQConnectionFactory;public class Receiver {        private static final String MQ_USER = "admin";        private static final String MQ_PWD = "admin";        private static final String MQ_URL = "tcp://localhost:61616";        private static final String MQ_QUEUE_DEFAULT = "testQueue";                public static void main(String[] args) throws JMSException {                // 创建JMS连接工厂                ConnectionFactory factory = new ActiveMQConnectionFactory(MQ_USER, MQ_PWD, MQ_URL);                // 通过工厂获取链接并启动                Connection connection = factory.createConnection();                connection.start();                // 创建session                Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);                // 创建destination 消息目的地                Destination destination = session.createQueue(MQ_QUEUE_DEFAULT);                // 根据destination初始化一个消费者                MessageConsumer consumer = session.createConsumer(destination);                while (true) {          TextMessage msg = (TextMessage) consumer.receive(1000*1000);          if (null != msg) {              System.out.println("message has been received:" + msg.getText());          }                 }        }}

依次运行Receiver和Sender，控制台输出：

Sender

Receiver
