Question

我正在使用hibernate验证器在Spring MVC上进行验证，使用实体上的注释。

我的实体中有一个BigDecimal属性，我需要检查范围值验证。如下所示

@NotNull(message = "errors.range_1_5_Trades.mandatory")
@Pattern(regexp = "(^$[0-9])", message = "errors.only.numbersAllowed")
@Range(min = 1, max = 5, message = "errors.invalid.range")
@Column(name = "FEE_LESS_THAN_5")
private BigDecimal feeLessThan_5;

但是当我在Spring Controller中使用@Valid注释验证它时，它会抛出异常，如下所示
