Nginx反向代理的问题

Question

问题：使用Spring Boot开发，然后在服务器上使用Nginx反向代理8080端口，然后问题就出现了，在网站后台登录的时候，用户名和密码都正确，也提示登录成功，但是重定向的时候又回到了登录页，这里是加了拦截器的，直接访问后台的链接也直接回到登录页，感觉就像是登录成功后，session没有创建一样。如果加上8080端口的话就不会出现这样的问题，大家有经验的帮忙看一下，谢谢了。

相关代码：

对登录页面的请求：

    @GetMapping(value = "/login")
    public String login(HttpSession session,Model model){
        model.addAttribute("options",HaloConst.OPTIONS);
        User user = (User) session.getAttribute("user");
        //如果session存在，跳转到后台首页
        if(null!=user){
            return "redirect:/admin";
        }
        return "admin/admin_login";
    }

登录请求：

    @PostMapping(value = "/getLogin")
    @ResponseBody
    public String getLogin(@ModelAttribute("loginName") String loginName,
                           @ModelAttribute("loginPwd") String loginPwd,
                           HttpSession session){
        String status = "false";
        try {
            User aUser = userService.findUser();
            User user = null;
            if("false".equals(aUser.getLoginEnable())){
                status = "disable";
            }else{
                //验证是否是邮箱登录
                Pattern patternEmail = Pattern.compile("\\w[-\\w.+]*@([A-Za-z0-9][-A-Za-z0-9]+\\.)+[A-Za-z]{2,14}");
                Matcher matcher = patternEmail.matcher(loginName);
                if(matcher.find()){
                    user = userService.userLoginByEmail(loginName,HaloUtil.getMD5(loginPwd)).get(0);
                }else{
                    user = userService.userLoginByName(loginName,HaloUtil.getMD5(loginPwd)).get(0);
                }
                if(aUser==user){
                    session.setAttribute(HaloConst.USER_SESSION_KEY, user);
                    //重置用户的登录状态为正常
                    userService.updateUserNormal();
                    userService.updateUserLoginLast(new Date());
                    logsService.saveByLogs(new Logs(LogsRecord.LOGIN,LogsRecord.LOGIN_SUCCESS,HaloUtil.getIpAddr(request), HaloUtil.getDate()));
                    status = "true";
                }
            }
        }catch (Exception e){
            Integer errorCount = userService.updateUserLoginError();
            if(errorCount>=5){
                userService.updateUserLoginEnable("false");
            }
            userService.updateUserLoginLast(new Date());
            logsService.saveByLogs(new Logs(LogsRecord.LOGIN,LogsRecord.LOGIN_ERROR+"["+loginName+","+loginPwd+"]",HaloUtil.getIpAddr(request),new Date()));
            log.error("登录失败！：{0}",e.getMessage());
        }
        return status;
    }

拦截器：

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        Object obj = request.getSession().getAttribute(HaloConst.USER_SESSION_KEY);
        //如果user不为空则放行
        if(null!=obj){
            return true;
        }
        //否则拦截并跳转到登录
        response.sendRedirect("/admin/login");
        return false;
    }

注册拦截器：

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(loginInterceptor)
                .addPathPatterns("/admin/**")
                .excludePathPatterns("/admin/login")
                .excludePathPatterns("/admin/getLogin")
                .excludePathPatterns("/static/**");
    }

nginx配置（使用的宝塔面板配置的反向代理）：

server
{
    listen 80;
    server_name 域名;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/wwwroot/halo;
