消费者消息处理代码：

 1 package org.study.model;
 2 
 3 /**
 4  * RabbitMQ与Spring整合
 5  * 消费者消息处理类
 6  */
 7 public class MyListener {
 8     public void onMessage(String message) {
 9         System.out.println(" [RECV] : " + message);
10     }
11 
12 }

 

运行代码：

 1 package org.study.spring5;
 2 
 3 import org.springframework.context.ApplicationContext;
 4 import org.springframework.context.support.ClassPathXmlApplicationContext;
 5 
 6 /**
 7  * RabbitMQ与Spring整合
 8  * 消费者
 9  */
10 public class SpringConsumer {
11 
12     public static void main(String args[]) {
13         ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring/consumer-spring-config.xml");
14 
15     }
16 }
