SEVERE: The web application [/mall] registered the JDBC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

SEVERE: The web application [/mall] appears to have started a thread named [Abandoned connection cleanup thread] but has failed to stop it. This is very likely to create a memory leak.

SEVERE: The web application [/mall] 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.

解决方案

有没有那位大神碰到过，或知道是什么原因的

解决方案二：

可能是你的项目有些代码使用不当，导致了这个错误，基本上是哪些配置文件，你可以试试清空配置文件开启tomcat，然后一部分一部分添加内容开启tomcat，总可以找到的。我就是这么做的。。
