• 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

    经过排查和測试,发现项目中使用rabbitmq服务,而rabbitmq于昨天被重装了,从而里面的队列所有没有了,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。
