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?
