tomcat报错

tomcat报错 查看tomcat日志发现报错如下信息，请问这个报错的提示是什么意思，tomcat报错提示 严重：The web application [] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@94ade41]) and a value of type [org.hibernate.impl.SessionImpl] (value [SessionImpl(PersistenceContext[entityKeys=[],collectionKeys=[]];ActionQueue[insertions=[] updates=[] deletions=[] collectionCreations=[] collectionRemovals=[] collectionUpdates=[]])]) 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. 严重：The web application [] registered the JDBC driver [com.microsoft.sqlserver.jdbc.SQLServerDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

最满意答案

这个给你参考下，你的server.xml用到了，如果你使用eclipse什么的，可以用它自己的，就不会出错了，你使用了外部的tomcat 希望对你能有所帮助。
