Java 由于内存泄漏，我的网站一次又一次地停止

我用JavaSpring开发了一个网站。它有非常好的落脚点，大约5000/天。我已经在JavaApacheTomcat服务器上部署了它。每天停止2-3次。我遇到内存泄漏问题，但我无法确定该泄漏问题的位置或发生原因

我从Apache获得以下日志：

SEVERE: The web application [ ] created a ThreadLocal with key of type [org.springframework.core.NamedThreadLocal] (value [Locale context]) and a value of type [org.springframework.web.servlet.DispatcherServlet$1] (value [en_US]) 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.

这可能会帮助您找到泄漏的正确途径。JProfiler是一个可能有助于发现泄漏的工具，如果它存在的话。@LukeSpringWalker不，我没有这个工具。你能告诉我怎么用吗？@CodeHunter我很久以前用过，我不记得怎么用了，但它很直观。有一些关于它的视频和教程。
