Spring java.lang.IllegalStateException:提交响应后无法创建会话 [英] Spring java.lang.IllegalStateException: Cannot create a session after the response has been committed

问题描述

我的 spring 应用程序中存在会话管理问题，这是场景.当用户打开我的应用 URL 时，它会要求提供凭据并登录.用户登录后，如果他打开一个新选项卡并粘贴我的应用 URL，它会再次要求提供凭据并登录.

I am having a session management issue in my spring application, here is the scenario. When a user opens my app URL it'll ask for credentials and logs in. After the user looged in and if he open a new tab and paste my app URL it'll ask for credentials again and user logs in.

现在，如果用户在 tab1 中注销，并且用户想在第二个 tab 中执行任何操作，则用户会收到以下堆栈跟踪的错误并注销.

Now if the user logs out in tab1 and if user wants to performs any operation in second tab user gets an error with below stacktrace and logs out.

这是我的FlashRecyclingFilter

@Component
public class FlashRecyclingFilter extends OncePerRequestFilter {
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
        throws ServletException, IOException {
    super.doFilter(request, response, filterChain);
    IFlash flash = new Flash(request.getSession());
    flash.recycle();
    }
}

当用户在另一个选项卡中注销时，如何确保用户应该能够在一个选项卡中执行操作?任何人都可以帮我解决我的问题吗?

How do I make sure user should be able to perform operations in one tab when the user is logged out in another tab? Can anyone please help me with my issue?

推荐答案

发生的情况是 Spring 可能将重定向发送到登录页面，而您的自定义过滤器尝试创建会话(这无法完成，因为响应已经发送).

What happens is that Spring probably sends redirect to the login page, while your custom filter tries to create session (which can not be done as the response has been already sent).

您应该修改过滤器，使其不会急切地自行创建会话:

You should modify your filter so that it does not eagerly create the session on its own:

super.doFilter(request, response, filterChain);
HttpSession session = request.getSession(false);
if (session != null) {
    IFlash flash = new Flash(session);
    flash.recycle();
}
