在我的代码中使 portletRequest 会话无效后，我收到以下异常

我的会话失效代码如下：顺便说一下，这个方法是从另一个方法调用的，这个方法有@ActionMapping标签注释。

 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 stackoverflow 中发现了一个与会话失效 IllegalStateException: getAttribute: Session already invalidated相关的问题 ，但在我的情况下我无法从中得到太多。

有人可以帮助我在发生此错误时如何解决此问题，当控件转到 Spring 代码时，因此我无法解决此问题？

我从来没有使用过 WebLogic，但是从这里的 JavaDoc中我可以看出，getPortletSession()如果你想使现有会话无效，那么调用已经是错误的想法，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。

您需要的方法是getPortletSession(boolean create)，调用时需要传递false，如果调用方法没有可用的会话，它可能会返回null值，因此您也需要处理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，因为从我在 JavaDocs中看到的内容来看，无法确定会话是否已经失效。所以无论如何我们都只是无效，如果 IllegalStateException 被抛出，则忽略它，因为会话已经无效。

另外，不要忘记response.sendRedirect(exitURL);在使会话无效之前调用，我的直觉告诉我应该在之前完成。

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或创建了own threadorthread-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。解决方案是您可以创建自己的类Cloneable并克隆它。要了解更多信息，请查看此答案。

尝试使用 SessionStatus 代替：

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");
}

我不认为这会有所作为，但值得一试。
