j_spring_security_logout没有配置logout-success-url

Question

我想手动重定向spring的logOut，如果用户logOuts需要保存日期 但我不能重定向它。

我的spring-security.xml如下：

<security:logout invalidate-session="true" logout-success-url="/login?logout=1" delete-  cookies="JSESSIONID"/>

我的jsp页面：

  <spring:url var="logoutUrl" value="/j_spring_security_logout" />
        <li><a id="button" href="${logoutUrl}">Logout</a></li>

然后我想检查注销参数，如：

  RequestMapping(value = "/login", method = RequestMethod.GET)
    public String getLoginForm(@ModelAttribute("user") User user, Model      model,@RequestParam(value = "logout", required = false) String logout)
 {
    {
        try {
            log.info("Opening Login page");
            model.addAttribute("org.springframework.validation.BindingResult.user", model.asMap().get("addUserForm"));
            ModelAndView modelAndView = new ModelAndView();
           if (logout != null) {//logout is always null
               //save date 
               modelAndView.addObject("msg", "You've been logged out successfully.");  

               }
            } catch (Exception er) {
            log.error("Error in opening Login page" + er);
        }
        return "/login";
    }
