tomcat启动报错,无法创建 bean listenerStatusChangeDealHandler, no queue 'STOCK.NOTIFY\_CHANGE.INTER.CACHE.QUEUE' in vhost

从启动日志来看，有时候仅会看到内存泄漏，而没有与queue相关的日志，很容易走错方向。

经过排查和测试，发现项目中使用rabbitmq服务，而rabbitmq于昨天被重装了，从而里面的队列全部没有了，导致项目启动时初始化bean时候报错。

有趣的是，之前rabbitmq停止服务时，该项目启动正常，而rabbitmq服务提供服务，且某一指定队列不存在时，项目却无法正常启动，

由此可见，代码的健壮性有待改进哪。
