java - 在 Spring Controller 中维护相同的 session

Question

我有两个 Controller UserSignInController 和 PageNavigationController。我想在两个 Controller 中维护相同的 HttpSession，但我在 diff 页面中发现了 diff session 。我还在 Controller 页面中添加了 @SessionAttributes("userDetails")。请告诉我如何操作我创建了这个？

用户登录 Controller

@RequestMapping(value="/analyzeinternet1.html", method=RequestMethod.GET)
    public ModelAndView getSocialMediaAdmin(HttpSession session, Model model) {
        LOG.info(" session..." + session);
        ModelAndView mv = null;

        UserProfile up = (UserProfile) session.getAttribute("userDetails");
        if(up == null) { //Checking whether the user is already signed up or not. If not, the user is redirected to login page. 
            LOG.info("No user in session...");
            mv = new ModelAndView("redirect:/login.html");
        } else {
            LOG.info("User in session..." + up);
            mv = new ModelAndView("internetanalyze");
            model.addAttribute("userDetails", up);
            session.setAttribute("userDetails", up);
            mv.addObject("clientId", up.getUserId());
        }

        LOG.info(mv);
        return mv;
    }

页面导航 Controller

@RequestMapping(value="/analyzeinternet.html", method=RequestMethod.GET)
    public ModelAndView getAnalyzeInternet(HttpSession session, Model model) {
        LOG.info("-----session..." + session);
        //LOG.info("-----userprofile..." + userDetails);
        ModelAndView mv = null;
         up = (UserProfile) session.getAttribute("userDetails");
            LOG.info("User in session..." + up);
            mv = new ModelAndView("internetanalyze");
            //mv.addObject("clientId", up.getUserId());
            return mv;
    }

两个 session ID 不同，我的重定向代码是

<a href="<%=request.getContextPath()%>/analyzeinternet.html">

您的意思是您从一页浏览应用程序到第二页，并且第二页使用 PageNavigationController，但您没有获得相同的 session ？您如何检查它是否不是同一个 session ？您确定在 session 中设置了 userDetails 吗？

还要检查 session cookie 是否在请求中正确传递。您可以使用firebug或chrome控制台检查响应和请求 header 中的cookie值。
