Spring boot 集成ActiveMQ（包含双向队列实现）

　　集百家之长，成一家之言。 

1、 下载ActiveMQ

https://mirrors.tuna.tsinghua.edu.cn/apache/activemq/5.15.9/apache-activemq-5.15.9-bin.zip

2、新建 Maven 项目 activemq

3、pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

</project>

4、ActiveMQStarter.java

package com.java;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * 主启动类
 *
 * @author Logan
 * @version 1.0.0
 * @createDate 2019-05-08
 *
 */
@SpringBootApplication
public class ActiveMQStarter {

    public static void main(String[] args) {
        SpringApplication.run(ActiveMQStarter.class, args);
    }

}

5、SendMessageController.java

package com.java.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * 发送消息类
 *
 * @author Logan
 * @version 1.0.0
 * @createDate 2019-05-08
 *
 */
@RestController
public class SendMessageController {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    /**
     * 发送到的队列名
     */
    private String destinationName = "handle-queue";

    @GetMapping("/send")
    public String send(String params) {
        System.out.println("[ 收到请求 ]");

        jmsMessagingTemplate.convertAndSend(destinationName, params);

        System.out.println("[ 返回响应 ]");
        return "您的任务已提交";
    }

    @JmsListener(destination = "result-queue") // 监听处理结果队列
    public void handle(String message) {
        System.out.println("[ 收到消息处理结果 ]" + System.currentTimeMillis());

        System.out.println(message);
    }

}

6、MessageHandler.java

package com.java.listener;

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

/**
 * 任务处理器，监听ActiveMQ队列中的消息，消费并处理
 *
 * @author Logan
 * @version 1.0.0
 * @createDate 2019-05-08
 *
 */
@Component
public class MessageHandler {

    @SendTo("result-queue") // 处理结果发送到 "result-queue" 队列中
    @JmsListener(destination = "handle-queue") // 监听处理消息队列
    public String handle(String message) {
        System.out.println("[ 处理器开始处理消息 ]" + System.currentTimeMillis());

        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        System.out.println(message);

        System.out.println("[ 处理器处理消息完成 ]" + System.currentTimeMillis());

        return "消息“" + message + "”处理完成";
    }

}

7、application.properties

spring.activemq.broker-url=tcp://127.0.0.1:61616
spring.activemq.user=admin
spring.activemq.password=admin
spring.activemq.in-memory=true
spring.activemq.pool.enabled=false

8、启动

运行 activemq.bat 启动ActiveMQ 服务

运行ActiveMQStarter.java 启动项目

9、测试

浏览器输入 http://127.0.0.1:8080/send?params=Hello

浏览器快速收到响应 “您的任务已提交”，控制台日志如下：

[ 收到请求 ]
[ 处理器开始处理消息 ]1557311835328
[ 返回响应 ]
Hello
[ 处理器处理消息完成 ]1557311840353
[ 收到消息处理结果 ]1557311840369
消息“Hello”处理完成

双向通信正常！

查看消息队列服务

浏览器输入 http://127.0.0.1:8161

登录 admin/admin

可查看所有队列以及生产者和消费者情况
