使用Hibernate-Validate进行参数校验

@NotBlank(message = "项目不能为空")
  @Length(max = 12, message = "用户真实姓名不能超过12位")
  @Length(min = 11, max = 11, message = "手机号长度不正确")
  @Email
  @Min(value = 0, message = "最小值为0")
  @Max(value = 2, message = "最大值为2")
  @ApiModelProperty(value = "项目id")
  @TableField("PROJECT_ID")
  private String projectId;
    
    @NotBlank(message = "手机号不能为空")
    @Pattern(regexp = "^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1}))+\\d{8})$", message = "手机号格式不正确")
    private String mobile;
   
    @NotBlank(message = "验证码不能为空")
    private String smsCode;

@PostMapping("login")
    public GraceJSONResult login(@Valid @RequestBody RegistLoginBO registLoginBO,
                                      HttpServletRequest request) throws Exception {

@ExceptionHandler(MethodArgumentNotValidException.class)
    @ResponseBody
    public GraceJSONResult returnNotValidException(MethodArgumentNotValidException e) {
        BindingResult result = e.getBindingResult();
        Map<String, String> errors = getErrors(result);
        return GraceJSONResult.errorMap(errors);
    }
    public Map<String, String> getErrors(BindingResult result) {
        Map<String, String> map = new HashMap<>();
        List<FieldError> errorList = result.getFieldErrors();
        for (FieldError fe : errorList) {
            // 错误所对应的属性字段名
            String field = fe.getField();
            // 错误信息
            String message = fe.getDefaultMessage();
            map.put(field, message);
        }
        return map;
    }
