@CreationTimestamp 和 @UpdateTimestamp 不适用于 LocalDateTime

Posted 2023-02-26

【中文标题】@CreationTimestamp 和 @UpdateTimestamp 不适用于 LocalDateTime

【英文标题】：@CreationTimestamp and @UpdateTimestamp is not working with LocalDateTime

【发布时间】：2019-04-09 20:00:01

【问题描述】：

我正在尝试将@CreationTimestamp 和@UpdateTimestamp 与LocalDateTime 类型一起使用，但它给了我org.hibernate.HibernateException: 生成器注释不支持的属性类型@CreationTimestamp 异常。

我使用的是 5.0.12.hibernate 版本和 java 8 LocalDataTime，

有什么方法可以将 @UpdateTimestamp 和 @CreationTimestamp 与 Java 8 LocalDateTime 一起使用？

【问题讨论】：

你为什么要为此挣扎。只需为您的 POJO 创建日期时间和更新的日期时间添加 2 个字段。它会解决你的问题

【参考方案1】：

您的问题是您的 Hibernate 版本。您需要将其升级到版本 5.2.3 才能将 @CreationTimestamp 和 @UpdateTimestamp 与 LocalDateTime 一起使用。有关更多信息，您可以查看此blog。只需升级您的 Hibernate，一切都会按预期工作。

如果您不想更新 Hibernate 版本，可以将字段类型更改为以下之一。

java.util.Date java.util.Calendar java.sql.Date java.sql.Time java.sql.Timestamp

【讨论】：

我使用的是 Hibernate 5.4.14.Final 版本，我仍然有同样的问题

@VinayaNayak ：确保没有其他注释覆盖列的类型。
