【rabbitMQ】springboot整合rabbitMQ模拟简单收发消息

1.创建项目和模块

2.添加rabbitMQ依赖

3.启动rabbitMQ服务

4.引入rabbitMQ服务端信息

5.通过单元测试模拟业务发送消息

6. 接收消息

1.创建项目和模块

2.添加rabbitMQ依赖

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

3.启动rabbitMQ服务

4.引入rabbitMQ服务端信息

spring:
  rabbitmq:
    port: 5672
    host: localhost
    username: guest       rabbitMQ服务端账号
    password: guest       rabbitMQ服务端密码  
    virtual-host: /       虚拟机地址

rabbitMQ服务端用户和虚拟机操作可参考

5.消费者监听队列

package com.example.consumer.mqListener;


import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Slf4j
@Component
public class Listener {

    @RabbitListener(queues = "bbb.queue")
    public void bbb(String msg){
        System.out.println("消费者收到了bbb.queue的消息:【"+msg+"】");


    }
}

即

运行

6.通过单元测试模拟业务发送消息

package com.example.publisher;

import org.junit.jupiter.api.Test;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
public class SendMessage {


    @Autowired
    private RabbitTemplate rabbitTemplate;


    @Test
    void  TestSend(){
        String queueName="aaa.queue";
        String msg="我正在使用rabbitMQ";
        rabbitTemplate.convertAndSend(queueName,msg);

    }


}
