我的会话失效代码如下:
顺便说一下,这个方法是从另一个带有@ActionMapping
标签注解的方法调用的。
private void exit(PortletRequest request, ActionResponse response)
logger.debug("Entering exit");
String exitURL = Constants.EXIT_URL;
request.getPortletSession().invalidate();
try
response.sendRedirect(exitURL);
catch (IOException ex)
logger.error("Error: IOException: ", ex.getMessage());
throw new RuntimeException(ex);
logger.debug("Exiting exit");
我在 *** 中发现了一个与会话失效有关的已经存在的问题 IllegalStateException: getAttribute: Session already invalidated 但就我而言,我无法从中得到太多。
当这个错误发生时,当控制转到 Spring 代码并且我无法解决这个问题时,有人可以帮我解决这个问题吗?
【问题讨论】:
您可以尝试将SessionStatus status
添加到您的方法签名中,然后执行status.setCompleted()
,而不是通过请求使会话无效吗?另外,请在执行response.sendRedirect()
后尝试使无效。
request.getPortletSession().invalidate()的执行点没有出现错误;甚至在 response.sendRedirect(exitURL); 的时候也没有。它发生在我的控制超出我的书面代码时,即当控制回到弹簧时。所以我猜上述语句的执行顺序并不重要。
会话范围的 bean 会导致任何问题吗?从某种意义上说,我必须分别使它们无效吗?如果是,我应该什么时候使它们无效,我怎样才能使它们无效?
从堆栈跟踪来看,似乎异常发生在 LifeRay 的 servlet 过滤器之一中。我的猜测是 LifeRay 在您已经使会话无效后试图访问它。我建议尝试上面提到的 SessionStatus 和 .setCompleted()。由于它不直接作用于 Session,它可能会延迟实际的会话失效,直到所有进程都完成之后。
是的,我相信这正是正在发生的事情,现在我不明白如何解决您的问题,您能否将示例代码与您的答案相关联?
【参考方案1】:
尝试改用 SessionStatus:
private void exit(PortletRequest request, ActionResponse response, SessionStatus status)
logger.debug("Entering exit");
String exitURL = Constants.EXIT_URL;
status.setComplete(); // instead of request.getPortletSession().invalidate()
try
response.sendRedirect(exitURL);
catch (IOException ex)
logger.error("Error: IOException: ", ex.getMessage());
throw new RuntimeException(ex);
logger.debug("Exiting exit");
我认为这不会产生影响,但值得一试。
【讨论】:
我不确定这些信息是否有帮助,但我认为值得提供这些信息: 1. 我创建了会话范围的 bean,并使用代理创建 (我从未使用过 WebLogic,但从 JavaDoc here 我可以看出,如果您想使现有会话无效,那么调用 getPortletSession()
已经是错误的想法,因为它在 JavaDocs 中说过:
Returns the current portlet session or, if there is no current session,
creates one and returns the new session.
因此,它会创建一个新会话,如果您只想使现有会话无效,这不是您想要的。
你需要的方法是getPortletSession(boolean create)
,调用的时候需要传入false,如果调用的方法没有可用的session,可能会返回null值,所以你也需要处理null:
PortletSession current = request.getPortletSession();
if (current != null) try
current.invalidate();
catch (IllegalStateException ignored)
// ok: session is already invalidated
我们需要捕获这个异常,因为从我看到的in JavaDocs 来看,无法确定会话是否已经失效。所以无论如何我们只是无效,如果 IllegalStateException 被抛出,则忽略它,因为会话已经无效。
另外,不要忘记在使会话无效之前调用response.sendRedirect(exitURL);
,我的直觉告诉我应该在此之前完成。
【讨论】:
这里的response.sendRedirect(exitURL)有什么用? 来自主题启动器的代码 sn-p。他需要发送重定向响应。您可以在 JavaDoc 中阅读更多相关信息:portals.apache.org/pluto/portlet-2.0-apidocs/javax/portlet/…【参考方案3】:无论如何,如果你想这样做,你可以做到。你有一个解决方案。
确保在请求线程内运行此方法,spring 为每个请求分配一个线程。如果您在请求之外,您将无法从请求中得到任何东西。如果您使用过@Async
,或者如果您创建了own thread
或thread-pool
来执行此方法,则无法并行执行。我认为应该是您面临的问题。解决方案是您可以将自己的类创建为Cloneable
并克隆它。要了解更多信息,请查看此答案。
