需求：使用Spring整合RabbitMQ

步骤：

生产者

1.创建生产者工程

2.添加依赖

3.配置整合

4.编写代码发送消息

消费者步骤相同

消费者代码

监听器

package com.listener;import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;public class SpringQueueListener implements MessageListener {@Overridepublic void onMessage(Message message) {//监听到之后直接打印System.out.println(new String(message.getBody()));}
}

package com;import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;@ContextConfiguration(locations = "classpath:spring-rabbitmq-consumer.xml")
@RunWith(SpringJUnit4ClassRunner.class)
public class ConsumerTest {@Testpublic void Test1() {//使消费者一致在监听队列while (true) {}}
}
//效果是监听器一直处于监听队列消息的状态，只要队列区有消息就获取
