spring-mvc - 处理 session 超时？

Question

如何在 spring mvc 3.2 中处理 session 超时，例如 30 分钟后它应该重定向到 index.html。

尝试使用拦截器，但忽略了 web.xml 中指定的 session 超时值。

spring-servlet.xml

 <mvc:interceptors>   
   <bean class="com.server.utils.AuthenticationTokenInterceptor" />   
   </mvc:interceptors>

网络.xml

<session-config>
    <session-timeout>30</session-timeout>
  </session-config>

 @Override  
    public boolean preHandle(HttpServletRequest request,HttpServletResponse response, Object handler) throws Exception {   
     try  
        {System.out.println("Inside Interceptor");   
            HttpSession session = request.getSession();   
            String authToken = (String) session.getAttribute("userId");   
               System.out.println("Interceptor invoked For Auth token");   
                if(authToken==null || authToken.equals(""))   
                {   
                    System.out.println("Auth Token time Out");   
                 response.sendRedirect(servletContext.getContextPath()+"/login");   
                    return false;   
                }   
                else  
                {   
                 return true;   
                }   
       }catch(Exception ex)   
           {   
           ex.getMessage();   
          response.sendRedirect(servletContext.getContextPath()+"/login");   
              return false;   
           }   
        }   


    @Override  
    public void postHandle(HttpServletRequest request,   
          HttpServletResponse response, Object handler,   
        ModelAndView modelAndView) throws Exception {   
   }   

   @Override  
 public void afterCompletion(HttpServletRequest request,   
         HttpServletResponse response, Object handler, Exception ex)   
            throws Exception {   
    }

<system.web>
    <sessionState allowCustomSqlDatabase="true" mode="SQLServer"
    sqlConnectionString="SQLServerConnection" cookieless="false" timeout="60">
   </sessionState>
   <authentication mode="None" />
   <compilation debug="true" targetFramework="4.5" />
   <httpRuntime targetFramework="4.5" maxRequestLength="52428800" />
</system.web>

- 此代码放在 web.config 中

  $.timeoutDialog
    ({
        timeout: 60 * 60,
        countdown: 20,
        logout_url: '@Url.Action("Logout", "Login")', restart_on_yes: true
    });

• 此代码放在您的设置页面中，并使用“timeout_dialog.js”。其他细节设置在 .js 文件中。

     public override void OnActionExecuting(ActionExecutingContext 
    filterContext)
  {
  
      if (filterContext.HttpContext.Session["UserID"] == null)
      {
          if (filterContext.HttpContext.Request.IsAjaxRequest())
          {
              filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
              filterContext.Result = new JsonResult
              {
                  JsonRequestBehavior = JsonRequestBehavior.AllowGet,
                  Data = new
                  {
                      Exception="error"
                  }
              };
          }
          else
          {
              filterContext.Result = new RedirectToRouteResult(
              new RouteValueDictionary
              {
                  { "controller", "Login" },
                  { "action", "Login" }
              });
                  //return;
          }
          return;
  
      }
      base.OnActionExecuting(filterContext);            
  }
  

  此代码放在普通类文件夹文件中的 filter.cs 中。
