@NotBlank(message = "手机号码不能为空", groups = {Insert.class})
@NotNull(message = "手机号不能为空", groups = {Insert.class})
@Length(min = 11, max = 11, message = "手机号只能为11位")
@Pattern(regexp = "^[1][3,4,5,6,7,8,9][0-9]{9}$", message = "手机号格式有误")
private String phoneNumber;

数字校验数值：

  @ApiModelProperty(value = "面积")
  @DecimalMin(value = "0.0", message = "面积不能低于0")
