Tomcat startup error. The corresponding queue cannot be found, causing memory leakage.

Tomcat startup error: Unable to create bean listenerStatusChangeDealHandler, no queue 'stock. policy_change.inter.cache.queue 'in vhost

From the startup log, sometimes only the memory leakage is seen, and there is no log related to the queue, it is easy to go in the wrong direction.

After investigation and testing, it was found that the rabbitmq service was used in the project, and rabbitmq was reinstalled yesterday, so that all the queues in it were lost, resulting in an error during bean initialization at project startup.

Interestingly, when rabbitmq was stopped, the project started normally, while the rabbitmq service provided services. If a specified queue does not exist, the project could not be started normally,

It can be seen that the robustness of the code needs to be improved.
