Spring java.lang.IllegalStateException：在提交响应后无法创建会话
我在我的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，如果他打开一个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。

@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，如何确保用户能够在一个选项卡中执行操作？ 有人可以帮我解决我的问题吗？
会发生什么是Spring可能会将重定向发送到登录页面，而您的自定义filter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filter，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(); }
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。
