Question

我在Spring应用程序中遇到会话管理问题，这是方案。当用户打开我的应用程序URL时，它会要求提供凭据并登录。用户进入后，如果他打开新选项卡并粘贴我的应用程序URL，它将再次请求凭据并且用户登录。

现在，如果用户在tab1中注销，并且如果用户想要在第二个选项卡中执行任何操作，则用户会在下面的堆栈跟踪中收到错误并注销。

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();
    }
}

当用户在另一个标签中注销时，如何确保用户能够在一个标签中执行操作？任何人都可以帮我解决我的问题吗？

Answer 1

Spring会发送重定向到登录页面，而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）。

您应该修改过滤器，以便它不会急切地创建会话：

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

Answer 2

检查您是否使用过rd.forward（）或rd.include（）。我们必须使用rd.include（）来解决该错误。尝试一次。

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