为什么会有内存泄漏警告？TOMCAT 6.0.35 允许 GC 工具。但它仍然会发出这样的警告。我很担心这些警告。请帮助我如何处理这些警告？任何帮助都将受到高度赞赏............提前致谢。

我对 Tomcat 6 和 Struts2 2.1.8 webapp（maven 3.0.3 + eclipse keepler + JDK 1.6.0_22）有同样的问题。我是struts2+tomcat开发的新手，不习惯解决这类问题。

在对我的代码进行了一些更改（并且不使用 svn 或 git ...）之后，在开始使用 mvn tomcat:redeploy 任务（女巫让我感到困惑）之后，我有同样的行为，不知道是什么导致部署失败（项目继续编译正常）。

这个错误对我来说似乎如此混乱和零描述，我已经阅读了许多相关的帖子。我试图更新 struts2 版本，因为我读过这种问题似乎在 struts2 2.3.3 中解决了（使用的是 2.1.8）。

https://issues.apache.org/jira/browse/WW-3768

我不知道为什么我只是在阅读 catalina 日志：

SEVERE: Error filterStart
12/02/2014 10:46:23 org.apache.catalina.core.StandardContext start
SEVERE: Context [/validador] startup failed due to previous errors

答案非常接近，在 localhost-date.log 中！这让我想到了 struts.xml 中一个糟糕的声明动作，解决起来如此简单且描述性如此之强，但仅阅读 catalina 日志就很难弄清楚。

SEVERE: Exception starting filter struts2

Caused by: Action class [aoc.action.signature.CompletePDFUpload] not found - action - file:/C:/apps/apache-tomcat-6.0.39/webapps/validador/WEB-INF/classes/struts.xml:74:83

我希望其他人错过了检查正确的日志并像我一样简单地解决他们的问题。
