Tapestry5 注销异常
我面临一个奇怪的问题,无法找出根本原因。这是问题陈述。
我有一张带有注销按钮的挂毯页面。当我单击注销按钮时,将执行下面的代码并收到异常。
// method which called onclick of logout button.
@OnEvent(value = EventConstants.ACTION, component = "tlogout")
public Object logout()
{
request.getSession(false).invalidate();
return "Login";
}
例外的是:

I am facing a strange issue and am not able to find out the root cause. Here is the problem statement.
I have one tapestry page with a logout button. When I click on the logout button, the code below is executed and I get the exception.
// method which called onclick of logout button.
@OnEvent(value = EventConstants.ACTION, component = "tlogout")
public Object logout()
{
request.getSession(false).invalidate();
return "Login";
}
Exception is:

感谢您的时间和评论!经过一番讨论,我终于找到了解决方案并与您分享。
就我而言,请求/响应通过
RMOpenEJBFilter
进行。因此,当我在代码中使会话无效时,它会在RMOpenEJBFilter
中崩溃,因为其内部代码在会话上进行处理。这是我的解决方案。
LogOutFilter
的过滤器。RMOpenEJBFilter
之前(出于过滤器链接的目的)。request.getSession(false).setAttribute("InvalidateSession", true);
RMOpenEJBFilter
处理请求(直到会话未失效)。现在控制权转到 LogOutFilter ,我在其中进行了检查以使会话无效。if (httpRequest.getSession(false) != null && httpRequest.getSession(false).getAttribute("InvalidateSession") != null) {
httpRequest.getSession(false).invalidate();
。
现在它工作正常
希望我的解决方案足够好,能够被接受。
如需任何说明,请随时与我联系。

Thanks for your time and your comments! With some good discussion I finally found the solution and are sharing it with you.
In my case request/response coming through
RMOpenEJBFilter
. So, when I invalidated the session in my code then it crashed inRMOpenEJBFilter
because its internal code process on session.So here is my solution.
LogOutFilter
.RMOpenEJBFilter
(for the purpose of Filter Chaining).request.getSession(false).setAttribute("InvalidateSession", true);
RMOpenEJBFilter
where it process the request (till the time session is not invalidated). Now control goes to theLogOutFilter
where I made a check to invalidate the session.if (httpRequest.getSession(false) != null && httpRequest.getSession(false).getAttribute("InvalidateSession") != null) {
httpRequest.getSession(false).invalidate();
}
And now it's working fine.
Hope my solution is good enough to be accepted.
Feel free to contact me for any clarification.

我认为你不需要过滤器。只需添加以下注销操作即可。
i think u don't need filter. just add following action for logout.
