destroy

问题 I am looking for an interceptor or a trigger to know that, all the context beans are destroyed and the applicationcontext instance is about to destroy itself. So I can do one process at the end of the application lifetime.

I thing it comes with the close() method of the applicationcontext. So it doesn't fit to my need Any ideas? Regards Ali 回答1: You can

问题 I know this question has been raised multiple times here and I have gone through all of them. But I didn't find a clear solution for the problem. I know the reasons for the occurrence of this error. I know that after using root.destroy() , there are still some jobs left to be completed and all that stuff.
