我已在 Apache Tomcat 7.0.41 中部署了一个 Struts 1.3 Web 应用程序。 Tomcat 服务器似乎经常挂起并且无法处理任何请求，在浏览器上显示页面未找到错误，类似于停止的 Tomcat 服务器，但实际上在 Windows 服务中 Tomcat 服务仍然显示为已启动。重启后服务器工作正常。
在 Apache Software Foundation\Tomcat 7.0\logs omcat7-stderr.2013-07-05.log 中记录了以下错误：
Jul 5, 2013 11:57:48 AM org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
SEVERE: The web application [/pms] appears to have started a thread named [File Reaper] but has failed to stop it. This is very likely to create a memory leak.

Web 应用程序确实包含一些具有 Struts 1.3
FormFile您应该配置数据库设置以与 Tomcat 服务器一起运行。您的后期配置未知，但我猜您只是没有在应用程序中包含数据库驱动程序，或者 Tomcat 服务器上未安装数据库驱动程序。
