The web application [] is still processing a request that has yet to finish。This is very likely........

1.问题

在做一些操作时，比如说添加之后再查询，重复多次之后发现数据无法继续添加，也无法查询出数据。此时前台和后台都没报错。当再次启动tomcat时，出现警告：

`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.`  

2.原因

个人认为是连接没有及时关闭，可能再加上内存不富裕，导致memeory leak。

3.解决方法

在动作结束之后及时关闭连接，可解决。
