Envers & "A different object with the same identifier value was already associated with the session"
我正在尝试在我的 hibernate 5 项目中使用 envers 以监视数据库中的更改。但是我遇到了 @Embeddable 元素的问题。
当我保存包含 @Embeddable 元素的实体时，出现以下错误：Caused by: javax.persistence.EntityExistsException: A different object with the same identifier value was already associated with the session : [entity_embedded_entity_AUD#{SETORDINAL=1, REV=com.bl.dpi.appli.example.hibernate.envers.audited.revision.UpperRevisionObject@7a814310, AuditedEntityWithEmedded_id=d9b141ce-5ac1-4209-969e-8229845dd606, REVTYPE=ADD}]
我尝试了很多方法来解决这个问题（Whosebug FTW！）但没有成功
这是我的 classes
