我的控制器有问题。我正在使用SpringMVC和hibernate的安全性

我有两个模型课：

User.java和Park.java有很多双向关系。通过这种关系，我将一个或多个停车场链接到一个用户。我需要为登录用户列出停车场。因此，在我的Park.controller中，我有一个方法可以获取记录的用户名

@RequestMapping(value = { path }, method = RequestMethod.GET)
    public String listParks(ModelMap model){
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        String name = auth.getName(); //get logged in username
        User user = userService.findBySso(name);
        logger.debug("Username = "+name);
        logger.debug("User = "+user.toString());
        List<Park> parks = parkService.findParkByUser(user);
        String pageTitle ="Elenco Park";
        model.addAttribute("parks", parks);
        model.addAttribute("pageTitle", pageTitle);
        model.addAttribute("cssActivePark", cssActivePark);
        return path+"/parks";
    }

@RequestMapping（value={path}，method=RequestMethod.GET）
公共字符串listParks（ModelMap模型）{
Authentication auth=SecurityContextHolder.getContext（）.getAuthentication（）；
String name=auth.getName（）；//登录用户名
User=userService.findBySso（名称）；
logger.debug（“用户名=”+名称）；
logger.debug（“User=“+User.toString（））；
List parks=parkService.findParkByUser（用户）；
字符串pageTitle=“Elenco公园”；
model.addAttribute（“公园”，公园）；
model.addAttribute（“pageTitle”，pageTitle）；
addAttribute（“cssActivePark”，cssActivePark）；
返回路径+“/parks”；
}

List parks=parkService.findParkByUser（user）

应为用户返回公园列表。在ParkDaoImpl中，ParkServiceImpl调用的此方法

@SuppressWarnings("unchecked")
    @Override
    public List<Park> findParkByUser(User user) {
        Criteria criteria = createEntityCriteria();
        if(user != null){

            criteria.createAlias("user", "users");
            criteria.add(Restrictions.eq("users", user);
        }
            criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);
            List <Park> parks = criteria.list();

        return parks;
    }

@SuppressWarnings（“未选中”）
@凌驾
公共列表findParkByUser（用户用户）{
标准=createEntityCriteria（）；
如果（用户！=null）{
标准.createAlias（“用户”、“用户”）；
标准。添加（限制。eq（“用户”，用户）；
}
criteria.setResultTransformer（criteria.DISTINCT\u ROOT\u实体）；
List parks=标准。List（）；
返回公园；
}

在列出公园时，我得到了这个例外
