springboot+activemq简单使用

1.安装activemq，我是本地安装了虚拟机装的mq,具体安装可参考https://www.cnblogs.com/shamo89/p/7645651.html

安装成功后访问页面,192.192.192:8161/admin 默认账号密码admin,admin

2.添加mq的依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-activemq</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-pool</artifactId>   --queue方式可以不添加
</dependency>

3.配置文件添加mq配置

使用queue(点对点)方式是，pool.enable要设置为false，默认使用的是queue方式，使用topic(订阅)方式是设置为true,同时要添加

spring.jms.pub-sub-domain=true。

4.创建生产者

package com.yypawn.lean.springbootactivemq.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;

import javax.jms.Destination;

/**
 * @Author: yang
 * @Description: 生产者
 * @Date: 2018-12-28
 * @Version: 1.0
 */
@Service("producer")
public class JMSProducer {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    public void sendMessage(Destination destination,final String msg){
        jmsMessagingTemplate.convertAndSend(destination,msg);
    }

    @JmsListener(destination = "out.queue")
    public void consumerMessage(String text){
        System.out.println("从out.queue队列收到回复为:" + text);
    }
}

5.创建消费者

package com.yypawn.lean.springbootactivemq.controller;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

import javax.jms.JMSException;
import javax.jms.Session;
import javax.jms.TextMessage;

/**
 * @Author: yang
 * @Description: 消费者1
 * @Date: 2018-12-28
 * @Version: 1.0
 */
@Component
public class JMSConsumerOne {

    @JmsListener(destination = "mytest.queue")
    public void reveiveQueue(TextMessage msg, Session session){
        try {
            System.out.println("test-queue 消息:" + msg.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

package com.yypawn.lean.springbootactivemq.controller;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Component;

/**
 * @Author: yang
 * @Description:  消费者2
 * @Date: 2018-12-28
 * @Version: 1.0
 */
@Component
public class JMSConsumerTwo {
    @JmsListener(destination = "mytest.queue")
    @SendTo("out.queue")//发送到out.queue队列,消息回馈
    public String receiveQueue(String text){
        System.out.println("Consumer2收到信息为:" + text);
        return "return message-" + text;
    }
}

5添加测试类

package com.yypawn.lean.springbootactivemq.controller;

import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.jms.Destination;

/**
 * @Author: yang
 * @Description: 测试
 * @Date: 2018-12-28
 * @Version: 1.0
 */
@RestController
@RequestMapping("test")
public class TestController {
    @Autowired
    private JMSProducer producer;

    @GetMapping("queue")
    public String queueSend(){
        Destination destination = new ActiveMQQueue("mytest.queue");
        for (int i = 0; i < 5; i++) {
            producer.sendMessage(destination,"this is a queue test");
        }
        return "ok";
    }
}

6.控制台打印

两个消费者共收到5条消息，消费者1收到2条，消费者2收到3条，消费者2收到的消息之后，反馈到out.queue队列

查看队列消息

简单的点对点消息测试完成了，关于订阅类型的测试还在尝试中！
