hibernate加入子类重复键

谢谢你的好奇，我需要你的帮助：）

因此，我创建了一个联合继承：父类称为“Action”，子类称为“AwardAction”和“LevelUpAction”。我用hibernate注释和3个表创建了3个类。它工作了好几个月，但最近出现了一个问题

问题是我们发现了两个具有相同id的条目“LevelUpAction”和“AwardAction”，它们与“Action”中的一个条目相关
[操作id=502]
/\
/\
[AwardAction id=502][LevelUpAction id=502]

这种情况不应该发生。每个levelUpAction和AwardAction都应该有自己的id

我们检查了代码，但没有发现任何问题。实际上，在这种情况下不应创建任何AwardAction。我们认为已经创建了一个LevelUpAction条目（如预期的那样），hibernate（出于未知原因）也创建了一个AwardAction条目

事实上，我想听听你对表格和课程的看法

课程：

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
public abstract class Action extends AbstractKeyEntity {

@Column
@NotEmpty
private String userKey;

@Column
@NotNull
private int points = 0;

protected Action() {
}

protected Action(String userKey, int points) {
    super();
    this.userKey = userKey;
    this.points = points;
}

public int getPoints() {
    return points;
}

public String getUserKey(){
    return userKey;
}
}
