[6. 接收消息](#6. 接收消息)
1.创建项目和模块
2.添加rabbitMQ依赖
<!-- rabbitmq依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
3.启动rabbitMQ服务
登录
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
java
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
java
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);
}
}
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
