几天来，我一直在尝试让复合键工作，查看网络上的许多示例，但由于它不起作用，所以仍然缺少一些东西。使用下面发布的代码，我目前遇到以下错误：无法确定类型：java.util.Set，表：USER_PROFILE，列：[org.hibernate.mapping.Column(userProfileDataFilter)]。

如果我从 UserProfile 对象中注释掉 UserProfileDataFilter ，那么一切都在保存和删除的情况下顺利运行。我已经将注释从变量移到了吸气剂，但运气不好。所以，我不确定还需要做什么，这就是我在这里请求帮助的原因。

非常感谢通过这个邪恶的注释迷宫提供的任何指导。

有时您将注释放在字段上，有时放在访问器（getter）上。始终将它们放在给定的类层次结构中的相同位置。

@IdIIRC，Hibernate 仅考虑与（或）注释放置在同一位置的@EmbeddedId注释。因此，如果@Id在 getter 上，并且您@OneToMany在字段上有 a，则@OneToMany注释将被忽略。
