Hibernate JPA错误：应为IdClass映射

我有一个@MappedSuperclass VoBusinessObject，其中包含id和版本

`

`

所有实体都扩展VoBusinessObject，因此它们继承id和版本

当我将我的应用程序部署到wildfly 8.2时，我得到

映射我的继承的正确方法是什么

问题是子类中的@ID。 恼人的是，Hibernate没有告诉实体它发生在哪里

致意

Heiko

您是否将

@Id

映射添加到

VoBusinessObject

的任何子类？您好，布莱恩，我看过这篇文章，但我没有复合键。

@IdClass(VoBusinessObject.class)
