Java Hibernate的PrimaryKeyJoinColumn问题

我有班上的人：

@Entity
@Table(name = "person") 
@Inheritance(strategy= InheritanceType.JOINED)
@SequenceGenerator(name = "person_seq", sequenceName = "person_seq", initialValue = 1,  allocationSize = 1)
public class Person implements Serializable{ 
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY, generator = "person_seq")
    @Column(name = "id")
    private long id;
} 

类用户：

@Entity
@Table(name = "user")
@PrimaryKeyJoinColumn(name = "id")
public class User extends Person{
    //some code
}

还有班上的客人：

@Entity
@Table(name = "guest")
@PrimaryKeyJoinColumn(name = "id")
public class Guest extends Person{
    //some code
}

这样，继承就可以很好地工作。问题是：所有三个表的列都具有相同的名称“id”。我想要最后两个名为“person\u id”的表中的外键

如果我更改了child上的列名，则会出现“在此结果集中找不到列名person\u id”异常：

@PrimaryKeyJoinColumn(name = "person_id")

@PrimaryKeyJoinColumn(name = "person_id", referencedColumnName = "id")

Guest guest = new Guest("Rodrigo", "10341367630", "1231", "55 35131 131", date, "1123123", "cpf", "guest");
guestDAO.create(guest);

我也尝试过这种方法（仍然得到相同的异常）：

有人知道如何解决这个问题吗

以及我得到异常的代码：

@PrimaryKeyJoinColumn(name = "person_id")

@PrimaryKeyJoinColumn(name = "person_id", referencedColumnName = "id")

Guest guest = new Guest("Rodrigo", "10341367630", "1231", "55 35131 131", date, "1123123", "cpf", "guest");
guestDAO.create(guest);

DAO中的代码：

public void create(Object objectRow) {
   session.save(objectRow);
   session.flush();
}

非常感谢

是否更改了数据库表定义？异常的完整堆栈跟踪是什么？导致异常的代码是什么？不，我没有。每次我试图保存客人或用户时，都会出现异常。关于这个异常，我将编辑并写入帖子。如果您的表不包含列，Hibernate显然无法读取该列中的任何值。更改表定义。哦，但是该列是由hibernate创建的。它存在于我的数据库中。表person的列id为PK，guest和user的列person\u id为PK。
