可能的根本原因包括-Xss的设置太低以及非法循环继承依赖性

Question

我的应用程序退出了大量并使用了许多罐子和工具.平台 - windows 2008服务器,Spring,hibernate,Quarts,mysql,tomcat-7.35

当我第一次部署并启动服务器完美工作时,但如果我重新启动,我会得到以下错误

堆栈跟踪说明tomcat在扫描应用程序的线程上的堆栈空间不足,正在寻找基于java的servlet配置.有三种方法可以解决这个问题.

• 增加堆栈大小 -Xss4m
• 如果您没有使用任何基于Java的Servlet配置添加metadata-complete="true"到web.xml中的Web应用程序,请告诉Tomcat不要扫描您的应用程序
• 限制tomcat扫描的jar文件.请参阅http://tomcat.apache.org/tomcat-7.0-doc/config/jar-scanner.html

你需要将-Xss4m传递给你的jvm来设置堆栈大小,-Xss10m会将它设置为10mb.

我在我的应用程序中也使用Hibernate和Spring注释,tomcat执行的扫描是查找Servlet 3.0注释,因此在使用hibernate和spring注释时仍然可以限制事物,因为spring和hibernate会扫描hibernate和spring annoations .

如果您将tomcat作为Windows服务运行,则需要通过procrun传递参数,因为这是启动jvm的可执行文件.procrun的文档位于http://commons.apache.org/daemon/procrun.html.tomcat7.exe真的是procrun.exe重命名,这意味着你所有的jvm选项都写入了registery下

基本服务定义在注册表项下维护:

HKEY_LOCAL_MACHINE \系统\ CurrentControlSet \服务\

其他参数存储在注册表中:

HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\ProcRun 2.0 \\ Parameters

在64位Windows上,procrun始终使用32位注册表视图来存储配置.这意味着参数将存储在:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\ProcRun 2.0 \

Tomcat一直在调整扫描仪在点发布之间的工作方式.尝试翻阅版本7.25,7.26 ...等以找到它破坏的版本,浏览该版本的发行说明,看看它们是否改变了扫描仪的工作方式.

你可以尝试做的另一件事是创建另一个war文件,其中包含WEB-INF\lib中的所有第三方jar,但不包含你的代码.如果你启动,看看你是否得到了这个错误,如果你这样做,那么应该用tomcat提交bug报告,并在github或其他一些免费的代码托管系统上为你提供复制问题的示例项目.我相信如果有错误,他们会修复它.

Answer 2

要为TC Server 2.9修复此问题,运行Tomcat 7.0.39我使用以下命令限制jars在启动期间跳过上下文配置:

org.apache.catalina.startup.ContextConfig.jarsToSkip=*.jar

在catalina.properties中.
