如何重写休眠集合联接列? [英] How to override hibernate collection join column?

问题描述

这是我的抽象父亲:

@MappedSuperclass   
public abstract class AbstractEntity implements Serializable {

    @OneToMany(fetch = FetchType.LAZY)
    @JoinColumn(name = "entity_no", referencedColumnName = "MY_COLUMN")
    private Set<CLASS_TYPE> list; 
}

我所有的实体都有此设置，但是每个实体都有不同的referencedColumnName.

All my entities has this set, but each entity has different referencedColumnName.

是否有一种方法可以仅覆盖@JoinColumn注释?

Is there a way to override only the @JoinColumn annotation?

推荐答案

您可以使用 AssociationOverride 批注.在您的情况下，它看起来像这样:

You can use AssociationOverride annotation. In your case it would look like this:

@Entity
@AssociationOverrides({
   @AssociationOverride(name = "list",
      joinColumns = @JoinColumn(referencedColumnName = "COLUMN_NEW_NAME"))
})
public class ConcreteEntity extends AbstractEntity {

}
