错误:找不到类型:java.time.LocalDate 的验证器

我正在开发一个使用bean验证的项目(Hibernate Validator 5.1.3.Final)。我的豆子有一个带有注释的属性。@Past

@Past(message = "A data deve estar no passado.")
private LocalDate dataAbertura;

但是,当验证发生时,我得到以下异常:

怎么了?休眠验证器不支持本地日期?


答案 1

实际上,要参考的问题是HV-874。Hibernate Validator 5.2.x确实增加了对一些新的Java 8日期/时间类型的支持。在这方面,我应该强调“一些”。尤其不受支持。Javadocs 说:LocalDateLocalDate

此类不存储或表示时间或时区。相反,它是对日期的描述,用于生日。如果没有其他信息(如偏移量或时区),它就无法表示时间线上的某个时刻。

如果没有时间轴上的瞬间,就不可能说给定的日期是在部分还是未来。首先,通过附加一个时区,可以陈述和回答这个问题。

如果您仍然认为在您的用例中使用 and 约束是有意义的,您可以随时实现自己的 约束,并使用约束映射文件中的元素通过 XML 注册它,如此所示。Past@FutureLocalDateConstraintValidatorLocalDateconstraint-definition

如果您使用的是 Hibernate Validator 5.2,则还可以使用 Java ServiceLoader 方法来注册其他实现 - 请参阅 ConstraintDefinitionContributor。后者目前是休眠验证器特定的功能。ConstraintValidator


答案 2

(validation-api-2.0.1.Final) 中有一个注释@Pastjavax.validation.constraints

它适用于java.time.LocalDate
