先前运行的tomcat类仍然存在 [英] tomcat classes from previous run remains

问题描述

我正在运行一个使用spring，hibernate，jsf等的应用程序.该应用程序还使用ha-jdbc使数据库高度可用.第一次部署该应用程序时，该应用程序运行平稳，但是当取消部署并重新部署该应用程序时，tomcat会出现以下错误:

以下Web应用程序已停止(重新加载，取消部署)，但是它们 先前运行的类仍会加载到内存中，从而导致内存不足 泄漏(使用探查器进行确认):

我想知道如何摆脱这个问题.有天才吗?

提前谢谢.

解决方案

使用探查器(visualvm会这样做)，创建堆快照，查找遗留的对象，查找引用链，并思考为什么仍要引用它们. /p>

，或者只需为每个部署重新启动tomcat.

i am running an application which uses spring, hibernate, jsf, etc. the application also uses ha-jdbc to make the databases highly available. when the application is deployed for the first time, the app runs smoothly, but when it is un-deployed and deployed back, tomcat gives the following error:

The following web applications were stopped (reloaded, undeployed), but their classes from previous runs are still loaded in memory, thus causing a memory leak (use a profiler to confirm):

i am wondering how to get rid of this problem. any genius?

thanks in advance.

解决方案

use a profiler (visualvm would do), do a heap snapshot, find the lingering objects, find the reference chain, and ponder why they are still referenced.

or, just restart tomcat for each deployment.
