spring boot 错误：Check your ViewResolver setup，springviewresolver

方法1.在请求方法上加注解：@ResponseBody，无需模板文件

    @ResponseBody
    @RequestMapping(value = "cs")
    public User cs() {
        //调用dao层
//        User user = userMapper.selectUserByName("beyondLi");
        User user = new User();
        user.setAge(12);
        user.setUsername("hello，world");
        return user;
    }
