Spring java.lang.IllegalStateException：在提交响应后无法创建会话

java session spring spring-mvc spring-security

我在春季应用程序中遇到会话管理问题，这是场景。当用户打开我的应用 URL 时，它会要求输入凭据并登录。在用户进入后，如果他打开一个新选项卡并粘贴我的应用程序URL，它将再次要求输入凭据并用户登录。

现在，如果用户在 tab1 中注销，并且用户想要在第二个选项卡中执行任何操作，则用户会收到以下堆栈跟踪的错误并注销。

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();
    }
}

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

答案 1

发生的事情是，Spring可能会将重定向发送到登录页面，而您的自定义过滤器会尝试创建会话（由于响应已经发送，因此无法完成此操作）。

您应该修改过滤器，以便它不会急切地自行创建会话：

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

答案 2

检查您是否使用了 rd.forward（）或 rd.include（）。我们必须使用rd.include（）来解决这个错误。尝试一次。
