@PostMapping(value = "/girls")
    public Result<Girl> girlAdd(@Valid Girl girl, BindingResult bindingResult) {
        if (bindingResult.hasErrors()) {
            return ResultUtil.error(1, bindingResult.getFieldError().getDefaultMessage());

通过@Valid，BindingResult 验证的时候仅限参数为对象

//更新
    @PutMapping(value = "/girls/{id}")
    public Girl girlUpdate(@PathVariable("id") Integer id,
                           @RequestParam("cupSize") String cupSize,
                           @RequestParam("age") Integer age) {
        Girl girl = new Girl();
        girl.setId(id);
        girl.setCupSize(cupSize);
        girl.setAge(age);

        return girlRepository.save(girl);
    }
由于金额上增加了不能为空，这里同样不能通过。

返回这个错误是应为在@Controller注解实用类上增加了异常处理
