ActiveMQ demo 测试

1.环境搭建

单节点windows 系统 版本apache-activemq-5.11.1 ，运行D:\apache-activemq-5.11.1\bin\win64\activemq.bat 即可

控制台界面 localhost:8161/admin  登陆 ，admin/admin123

 

引入all jar包

生产者：

package test.mq.helloworld;

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

import org.apache.activemq.ActiveMQConnectionFactory;

public class Sender {
    public static void main(String[] args)throws Exception {
        //active.xml 设置用户名密码</borker>
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("caolihua","caolihua","tcp://localhost:61616");
        Connection connection = connectionFactory.createConnection();
        //开启连接
        connection.start();
        //1.事务控制,2.自动签收（最好采用手动签收方式）二者都是创建一个新的线程去给队列确认消息消费完毕
        Session session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);
        //设置目的地为queue1队列
        Destination destination = session.createQueue("queue1");
        MessageProducer messageProducer = session.createProducer(null);
        for(int i =1;i<=5;i++){
            TextMessage textMessage = session.createTextMessage();
            textMessage.setText("我是消息内容，id为:"+i);
            //1.消息目的地2.消息内容3.是否持久化4.优先级(大量消息概率上满足，0-4：普通，5-9：加急)5.消息存活时间(毫秒级),超时出列
            //消息顺序消费机制，后续讨论
            messageProducer.send(destination, textMessage, DeliveryMode.NON_PERSISTENT, i, 1000*60);
            System.out.println("生产者："+textMessage.getText());
        }
　　　　//关闭连接会相应关闭session、producer、consumer
        if(connection!=null){
            connection.close();
        }
        
    }
}

 启动后，会看到控制台入待处理消息，入队消息，出队消息情况

 消费者：

package test.mq.helloworld;

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

import org.apache.activemq.ActiveMQConnectionFactory;

public class Receiver {

    public static void main(String[] args) throws Exception {
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("caolihua","caolihua","tcp://localhost:61616");
        Connection connection = connectionFactory.createConnection();
        connection.start();
        Session session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);
        Destination destination = session.createQueue("queue1");
        MessageConsumer messageConsumer = session.createConsumer(destination);
　　　　//循环监听
        while(true){
　　　　　　　//receive 阻塞在这里
            TextMessage msg = (TextMessage)messageConsumer.receive();
            if(msg==null) break;
            System.out.println("收到内容："+msg.getText());
        }
        
        if(connection!=null){
            connection.close();
        }
        
    }

}

执行循环监听消费，消费完了，出队消息有值了。

 

这是简单的P2P模式，还有发布订阅模式(广播方式)
