【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: 5672host: localhostusername: 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.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 {@Autowiredprivate RabbitTemplate rabbitTemplate;@Testvoid  TestSend(){String queueName="aaa.queue";String msg="我正在使用rabbitMQ";rabbitTemplate.convertAndSend(queueName,msg);}}

运行成功

如果队列未接收到msg，很可能是交换机未绑定该队列

因为生产者发送消息，经过交换机，再到队列，最终由消费者监听，接收消息

交换机绑定队列可以参考

6. 接收消息

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+"】");}
}
