大家请看下面代码找出不同

代码一

@Component
public class SpringRabbitListener {@RabbitListener(queues = "simple,queue")public void listenSimpleQueue(String msg){System.out.println("消费者接收到simple.queue的消息：{"+msg+"}");}}

代码二

@Component
public class SpringRabbitListener {@RabbitListener(queues = "simple.queue")public void listenSimpleQueue(String msg){System.out.println("消费者接收到simple.queue的消息：{"+msg+"}");}}

我找到最后人也呆了，人直接蒙了。

后来看出来了

大家知悉看这一句

@RabbitListener(queues = "simple.queue")

我把 "  . " 写为 ”  , “了

代码仔细，改错两行泪
