Hibernate Kotlin、JPA和@Transient

我有一个从Java迁移到Kotlin的实体类。inetAddress的一个属性用@Transient注释，以防止它被持久化到关系数据库中。但是，JPA Hibernate实现没有看到此注释，而是将其作为自己的字段放在数据库中。当用Java编写类时，这一切都能正常工作

有人知道如何正确注释这个Kotlin类，以便JPA/Hibernate能够看到@Transient注释，而不是将inetAddress属性放在数据库中吗

您正在注释字段，而不是注释getter。请注意，getter注释使用了不正确的类型java.beans.Transient，而不是正确的javax.persistence.Transient。

只需添加：

您正在注释字段，而不是注释getter。我已经很久没有使用Kotlin了，但我相信我在字段和getter上都添加了@Transient注释：@get:java.beans.Transient。这就是@get:部分的意思，不是吗？除非正确的注释不是java.beans.Transient，而是javax.persistence.TransientYes！非常感谢。这就是答案-如果你把它作为一个答案，我会接受并投票。你是在注释字段而不是注释getter。我已经很久没有使用Kotlin了，但我相信我在字段和getter上都添加了@Transient注释：@get:java.beans.Transient。这就是@get:部分的意思，不是吗？除非正确的注释不是java.beans.Transient，而是javax.persistence.TransientYes！非常感谢。这就是答案——如果你把它作为一个答案，我会接受并投票表决。
