springboot整合ActiveMQ

一：安装ActiveMQ

官网下载，解压

 

二：创建springboot项目，引入依赖   

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-activemq</artifactId>
</dependency>

<!--消息队列连接池-->
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-pool</artifactId>
    <version>5.15.0</version>
</dependency>

三：yml配置

spring:
  activemq:
    broker-url: tcp://localhost:61616
    in-memory: true
    pool:
      enabled: false

 

四：生产者发送消息

package com.lv.learning.jms;

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;

/**
 * Producer
 *
 * @author lvjijun
 * @version 1.0
 * @Date 2020-10-19
 */
@Service("producer")
public class Producer {
    /**
     * 也可以注入JmsTemplate，JmsMessagingTemplate对JmsTemplate进行了封装
     */
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    /***
     * description: 发送消息，destination是发送到的队列，message是待发送的消息
     * @param destination
     * @param message
     * @return void
     * @author lvjijun
     * @time 2020-10-19 10:52
     */
    public void sendMessage(Destination destination, final String message) {
        jmsMessagingTemplate.convertAndSend(destination, message);
    }

}

五：消费者接收消息

package com.lv.learning.jms;

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

/**
 * Consumer
 *
 * @author lvjijun
 * @version 1.0
 * @Date 2020-10-19
 */
@Component
public class Consumer {

    /***
     * description: 使用JmsListener配置消费者监听的队列，其中text是接收到的消息
     * @param text
     * @return
     * @author lvjijun
     * @time 2020-10-19 10:53
     */
    @JmsListener(destination = "mytest.queue")
    public void receiveQueue(String text) {
        System.out.println("Consumer收到的报文为:"+text);
    }

}

六：消费者接收并发送消息

package com.lv.learning.jms;

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

/**
 * Consumer2
 *
 * @author lvjijun
 * @version 1.0
 * @Date 2020-10-19
 */
@Component
public class Consumer2 {

    @JmsListener(destination = "mytest.queue")
    @SendTo("out.queue")
    public String receiveQueue(String text) {
        System.out.println("Consumer2收到的报文为:"+text);
        return "return message"+text;
    }

}

在receiveQueue方法上面加上注解@SendTo("out.queue")，意思是将return回的值，再发送的"out.queue"队列中

七：生产者发送并接收消息

package com.lv.learning.jms;

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;

/**
 * Producer
 *
 * @author lvjijun
 * @version 1.0
 * @Date 2020-10-19
 */
@Service("producer")
public class Producer {
    /**
     * 也可以注入JmsTemplate，JmsMessagingTemplate对JmsTemplate进行了封装
     */
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    /***
     * description: 发送消息，destination是发送到的队列，message是待发送的消息
     * @param destination
     * @param message
     * @return void
     * @author lvjijun
     * @time 2020-10-19 10:52
     */
    public void sendMessage(Destination destination, final String message) {
        jmsMessagingTemplate.convertAndSend(destination, message);
    }

    /***
     * description:  监听队列接收消息
     * @param text
     * @return void
     * @author lvjijun
     * @time 2020-10-19 16:06
     */
    @JmsListener(destination = "out.queue")
    public void consumerMessage(String text) {
        System.out.println("从out.queue队列收到的回复报文为:" + text);
    }

}
