ViewExpiredException，页面无法恢复
我尝试关注有关如何在 GlassFish 3.1 上处理 Mojarra 2.1.0（使用 RichFaces 4）中的 ViewExpiredException 的不同帖子。但我在 web.xml 中定义的内容似乎没有任何效果。我使用表单基础安全性，用户必须登录才能访问内容。我只希望 Glassfish (catalina) 在会话超时时将用户重定向到一个简单的 JSF 页面，并提供返回登录页面的链接。
我总是收到以下错误消息；
javax.faces.application.ViewExpiredException: viewId:/app_user/activity/List.xhtml - View /app_user/activity/List.xhtml could not be restored.
at com.sun.faces.lifecycle.RestoreViewPhase.execute(RestoreViewPhase.java:202)
at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101)
at com.sun.faces.lifecycle.RestoreViewPhase.doPhase(RestoreViewPhase.java:113)
当用户会话超时并在服务器日志中捕获异常时，我可以向谁重定向用户？
问候，克里斯。

I've tried to follow different posts on how to handle the ViewExpiredException in Mojarra 2.1.0 (with RichFaces 4) on GlassFish 3.1. But what I define in web.xml doesn't seams to have any effect. I use form base security and the user has to logon to access the content. I just want Glassfish (catalina) to redirect the user to a simple JSF page when the session times-out, with a link back to the login page.
I always get the the following error message;
javax.faces.application.ViewExpiredException: viewId:/app_user/activity/List.xhtml - View /app_user/activity/List.xhtml could not be restored.
at com.sun.faces.lifecycle.RestoreViewPhase.execute(RestoreViewPhase.java:202)
at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101)
at com.sun.faces.lifecycle.RestoreViewPhase.doPhase(RestoreViewPhase.java:113)
Who can I redirect the user when the user session has timed-out and trap the exception in the server log ?
Greetings, Chris.

您的方法对于同步 POST 请求应该非常有效。但是，您正在使用异步 (ajax) POST 请求。 ajax 请求的异常需要通过 JavaScript 中的
jsf.ajax.addOnErrorinit 函数或自定义ExceptionHandler。另请参阅
Your approach should work perfectly fine for synchronous POST requests. However, you're using asynchronous (ajax) POST requests. Exceptions on ajax requests needs to be handled by either the
jsf.ajax.addOnErrorinit function in JavaScript or a customExceptionHandler.See also
通过遵循此链接实现 异常处理工厂。一个很好的解决方案，您可以在其中设置例外导航规则，但可能有点长。感谢@BalusC 的帮助。
Solved the problem by following this link on implementing a ExceptionHandlerFactory. A nice solution where you can have an exception navigation rule, but maybe a bit long. Thanks for the help @BalusC.
