SEVERE: The web application [] is still processing a request that has yet to finish. This is very likely to create a memory leak. You can control the time allowed for requests to finish by using the unloadDelay attribute of the standard Context implementation.

看起来 tomcat 正在尝试卸载 webapp，但仍有一个请求正在运行。如果使用远程调试选项声明了 intellij 调试器，则可以将它附加到 tomcat 进程以查看该请求是什么。
