How to override hibernate collection join column?

Question

This is my abstract father:

@MappedSuperclass   
public abstract class AbstractEntity implements Serializable {

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

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

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

Answer 1

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 {

}

Answer 2

If you define annotations on the properties (i.e. getters) instead of on the fields, then you can override the public Set<CLASS_TYPE> getList() in each of the sub classes and define the @JoinColumn separately.
