Hibernate JPA规范单向OneTONE外部PK在存储库上引发错误

当尝试实现JPA2.2规范中指定的OneToOne关联示例时，我在存储库中遇到一个hibernate错误，声称它应该是一个复合密钥，尽管它不是

我知道有一种解决方案使用

@MapsId

，但是如果可能的话，我想让jpa规范解决方案发挥作用

@实体
公共类父级实现可序列化{
私有静态最终长serialVersionUID=3659483897253805915L；
@身份证
@GeneratedValue（策略=GenerationType.IDENTITY）
私人长id；
私有字符串名称；
Parent（）{}//jpa
//能手/二传手
}
@实体
公共类子级实现可序列化{
私有静态最终长serialVersionUID=6245572225910874612L；
@身份证
@奥内托内
@JoinColumn（name=“parent\u id”）
私人家长；
私有字符串名称；
Child（）{}//jpa
//能手/二传手
}

public接口子存储库扩展了JpaRepository{}

这会引发错误：
