tomcat启动报错，找不到相应的 queue，从而引发内存泄漏

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，非常easy走错方向。

依照 http://blog.csdn.net/wangjunjun2008/article/details/23375501 的方法能够看到具体日志，从而确定报错原因

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。
