1、springmvc過濾器request.getRequestDispatcher跳轉了，日誌也提示view(jsp)訪問了，瀏覽器卻沒動靜。

if(!isLogin){
            httpServletRequest.getRequestDispatcher("/toLogin").forward(httpServletRequest, httpServletResponse);
        }

17:57:55.062 [http-nio-8080-exec-3] DEBUG org.springframework.beans.factory.support.DefaultListableBeanFactory - Returning cached instance of singleton bean 'indexLogin'
17:57:55.062 [http-nio-8080-exec-3] DEBUG org.springframework.web.servlet.DispatcherServlet - Last-Modified value for [/toLogin] is: -1

17:57:55.064 [http-nio-8080-exec-3] DEBUG org.springframework.web.servlet.DispatcherServlet - Successfully completed request

頁面有個功能請求透過jquery ajax去請求controller，過濾器發現沒登入過濾器request.getRequestDispatcher發起登入請求跳到登入頁面，日誌記錄已經forward了（看圖2），但瀏覽器沒跳。

2、而且單獨請求/toLogin沒問題，直接出來登入頁面
