selectByExample 这个方法在调用的时候会报错

如下 在控制类中调用

 @RequestMapping(value = "test", method = RequestMethod.GET)
        public ModelAndView test(Country country) {
            ModelAndView result = new ModelAndView();
           List<Country> countryList = countryService.selectByExample(country);
            result.addObject("country", countryList);
            return result;
        }

控制台报错
