Kotlin，JPA和@Transient
我有一个实体类，我已经从Java迁移到Kotlin。 其中一个属性（ inetAddress ）用@Transient注释，以防止它被持久化到关系数据库。 但是，JPA（Hibernate实现）没有看到这个注释，并把它放在数据库中，因为它是自己的字段。 当这个类用Java编写时，这一切都可以正常工作。
有谁知道如何正确注释这个Kotlin类，以便JPA / Hibernate将看到@Transient注释，而不是将inetAddress属性放在数据库中？

你注释的领域，而不是注释吸气剂。 请注意，您的getter批注使用不正确的types（ java.beans.Transient ）而不是正确的javax.persistence.Transient 。
