The web application [FileIO_new_interface] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@1c27fa09]) and a value of type [java.lang.Class] (value [class com.cetc.di.io.impl.SayHelloImpl]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak. 这个错误是说，网络应用[FileIO_new_interface]创建了一个本地线程，但是在web application停止的时候，没有成功的被清除掉，这可能导致潜在的内存溢出错误，解决办法是手动杀掉相关的进程。方法是通过端口号，通过服务开放的端口号找出进程号，然后杀掉。
