一个exception

今天调错，发生了一个错误：
java.lang.IllegalStateException: ApplicationEventMulticaster not initialized [closed]

后来在stackoverflow看到了：
Have you enabled full DEBUG logging on org.springframework? That should tell you exactly who is trying to broadcast what event. What other spring configuration files are you pulling in? What versions of Spring Framework and Security are you using?

非常赞的解决方式。
