JPA实体继承有两个DiscriminatorColumn

Question

我需要你的帮助。

我有JPA map所需的以下值表。

我考虑了以下类结构。

班级＆＃34; NotificationCustomShippingPlan＆＃34;和＆＃34; PreviewCustomShippingPlan＆＃34;让每个人都成为DiscriminatorColumn＆＃34; Type＆＃34;。

但是班级＆＃34; ActivResultCustomShippingPlan＆＃34;和＆＃34; ActivResultCustomShippingPlan＆＃34;应该得到其他DiscriminatorColumn＆＃34; SubType＆＃34;。

我怎么能这样的地图？

我的感觉告诉我，这是不可能的。

@Entity
@Inheritance
@DiscriminatorColumn(name = "TYPE")
@Table(name = "CC_CUSTOM_SHIPPING_PLAN")
public abstract class AbstractCustomShippingPlan {
....
....
}


@Entity
@DiscriminatorValue("NOTIFICATION")
public class NotificationCustomShippingPlan extends AbstractCustomShippingPlan



@Entity
@DiscriminatorValue("PREVIEW")
public class PreviewCustomShippingPlan extends AbstractCustomShippingPlan


@Entity
@DiscriminatorValue("RESULTS")
@DiscriminatorColumn(name = "SUBTYPE")
public abstract class ResultCustomShippingPlan extends AbstractCustomShippingPlan {

    @Enumerated(EnumType.STRING)
    @Column(name = "CC_CSP_SUBTYPE")
    private ServiceType.Subtype subtype;

}


@Entity
@DiscriminatorValue("ACTIVE")
public class ActivResultCustomShippingPlan extends ResultCustomShippingPlan{
    .....
}



@Entity
@DiscriminatorValue("REPORTED")
public class ReportedResultCustomShippingPlan extends ResultCustomShippingPlan {
....

}
