这就是我在页面发出 Ajax 请求并且 session 超时后在浏览器中得到的内容，我正在实现 OmniFaces FullAjaxExceptionHandler .

这是控制台中显示的错误:
FullAjaxExceptionHandler: An exception occurred during processing JSF ajax request. Error page '/errorpages/expired.xhtml' will be shown.: javax.faces.application.ViewExpiredException: viewId:/login.xhtml - View /login.xhtml could not be restored.
最佳答案
我通过禁用 FullAjaxExceptionHandler 并实现我自己的 ViewExpiredExceptionHandler (ExceptionHandlerWrapper) 并在 Ajax 请求的情况下对响应进行硬编码来解决。
这篇文章中的 Douglas Junior 回答对我有用:Session timeout and ViewExpiredException handling on JSF/PrimeFaces ajax request
现在我有重定向的另一个问题，但那将是另一篇文章，谢谢大家的帮助。
关于 session 过期时的 Ajax 请求将 <partial-response> XML 纯文本返回给浏览器，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29632915/
