java - @CreationTimestamp 和@UpdateTimestamp 不适用于 LocalDateTime

Question

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 @CreationTimestamp 异常的不支持的属性类型。

我正在使用 5.0.12.hibernate 版本和 java 8 LocalDataTime,

有什么方法可以在 Java 8 LocalDateTime 中使用 @UpdateTimestamp 和 @CreationTimestamp 吗？

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。更多信息可以查看这个blog .只需升级您的 Hibernate，一切都会按预期工作。

如果您不想更新您的 Hibernate 版本，您可以将您的字段类型更改为以下之一。

• java.util.Date
• java.util.日历
• java.sql.Date
• java.sql.Time
• java.sql.时间戳
