找到堆栈中的关键信息作为本文的标题，这个堆栈中再一个扣人心悬的关键字就是reply-code=404.

分析

这个错误的堆栈信息是集成了rabbitmq的springboot项目再启动的时候报的，再报错中，它找不到的队列名字叫X01，这个队列再该项目中是作为消费者，来监听的队列。所以这个队列应该是再项目启动的时候与项目的消费监听进行绑定，如果绑定的时候发现，这个队列不存在，那么项目应该会自动的再rabbitmq中创建该队列，所以理论上应该不存在找不到队列这个问题的。
继续查看错误堆栈信息，发现错误信息

Failed to declare queue(s):[X01]
Cannot prepare queue for listener. Either the queue doesn't exist or the broker will not allow us to use it.

这个错误的始作俑者应该是上面的错误的第一行导致的，声明队列失败，导致后面监听无法绑定，导致了404。
上网查看，找到第一个解决方案，说是连接版本的问题，但是我并没有使用它提供的那个连接器，所以这个对我应该并不适用。
https://help.mulesoft.com/s/article/RabbitMQ-connector-fails-to-reconnect-after-reply-code-404-reply-text-NOT-FOUND-home-node-RabbitMQNodeName-of-durable-queue-exception
继续查找原因：
https://www.jianshu.com/p/1c4c42ff5114
找到这篇方案，但是查看自己的情况，当前的rabbitmq并没有宕机，而且重启客户端所在的应用也没有成功。

再探究竟

被其他的事情打断了下，3天之后，重新启动项目，想看看之前出现的错误，发现此时堆栈信息已经更换，报出来的堆栈信息如下：

在上面报错堆栈中捕捉关键信息，

reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'durable' for exchange 'charge' in vhost '/': received 'true' but current is 'false', class-id=40, method-id=10

登陆rabbitmq的web端，通过网页新建exchange charge,新建完成之后，重启服务，仍然是相同的错误。

通过web页面再次查看rabbitmq的管理界面，发现我的exchange charge 的future上没有D标识，说明这个exchange不是持久化的，与消费端声明的队列有出入，果断删除这个exchange，重启服务进行尝试。
发现服务已经不报错，再看rabbitmq的web端管理界面，发现charge已经重新创建，并且是持久化的。问题解决。

水落石出

原来我这个问题的原因是由于项目中的excharge与rabbitmq中现存的exchange属性不一样，导致项目启动的时候报声明queue报错.
