tomcat啟動報錯，找不到對應的 queue，從而引發記憶體流失

tomcat啟動報錯,無法建立 bean listenerStatusChangeDealHandler, no queue 'STOCK.NOTIFY_CHANGE.INTER.CACHE.QUEUE' in vhost

從開機記錄來看，有時候僅會看到記憶體流失，而沒有與queue相關的日誌，很容易走錯方向。

按照 http://blog.csdn.net/wangjunjun2008/article/details/23375501 的方法可以看到詳細日誌，從而確定報錯原因

經過排查和測試，發現項目中使用rabbitmq服務，而rabbitmq於昨天被重裝了，從而裡面的隊列全部沒有了，導致項目啟動時初始化bean時候報錯。

有趣的是，之前rabbitmq停止服務時，該項目啟動正常，而rabbitmq服務提供服務，且某一指定隊列不存在時，項目卻無法正常啟動，

由此可見，代碼的健壯性有待改進哪。
