其中，错误摘要如下：

  1. 无法声明exchange:　　Failed to declare exchange: Exchange [name=springCloudBus...
  2. 无法连接queue:　　Failed to declare queue: Queue
  3. 无法绑定:            Failed to declare binding: Binding [destination=springCloudBus

错误原因：

　　在搭建完Rabbit MQ 时，登录URL为localhost:15672,注意，这个端口控制台访问的端口，

　　但是在Spring Cloud 集成Rabbit MQ, 此时场景是，应用访问Rabbit MQ，那么此时依旧使用15672,这个控制台登陆端口的话，就出现上述问题

　　总结就是，15672只是控制台访问的端口，5672才是应用访问的正确端口。

解决方案：

　 根据上述分析，只要在参数配置中，将  spring.rabbitmq.port=15672 修改为 spring.rabbitmq.port=5672 ，即可解决上述问题。
