我试图按照不同的文章来介绍如何在GlassFish 3.1的Mojarra 2.1.0(带有RichFaces 4)中处理ViewExpiredException。但是我在web.xml中定义的内容对接缝没有任何作用。我使用表单基础安全性,用户必须登录才能访问内容。我只想让Glassfish(catalina)在 session 超时时将用户重定向到一个简单的JSF页面,并提供指向登录页面的链接。

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 session 超时并在服务器日志中捕获异常时,谁可以重定向用户?

克里斯,问候。

最佳答案

对于同步POST请求,您的方法应该可以很好地工作。但是,您正在使用异步(ajax)POST请求。 Ajax请求的异常需要由JavaScript中的jsf.ajax.addOnError init函数或自定义 ExceptionHandler 处理。
