I have two tables FoodAudit and IngredientAudit that mirror (plus some additional columns) the tables Food and Ingredient as part of a revisions system I am working on. Ideally, both of these tables would map to RevisionDetail<T> objects in my domain model, but that's proving a bit tricky. To accomplish this, I want to embed either a Food or Ingredient object as shown below.

@Entity
public class RevisionDetail<T> 
 @Column(name="RevisionId")
 private int revisionId;

 @Column(name="Operation")
 private Operation operation;

 @Embedded
 private T entity;

 public RevisionDetail() 

Rather than Id, though, on the audit tables the column is FoodId or IngredientId on the audit tables. I would think to use the @AttributeOverride annotation, but the column name changes depending on whether it is a Food or Ingredient object. How might I go about accomplishing this?

Consider to use Envers.

If you want to implement it by our own I suggest to use inheritance with @MappedSuperClass annotation on base type that will be extended by all auditable subclasses.

@MappedSuperClass
publci class BaseEntity
 @Id 
 Long id;

Than it is possible to map entity to revision:

@OneToOne
@JoinColumn(name="fk_id")
BaseEntity entity;

---

@AttributeOverride can override only attributes of @Column annotation. Column name.

@Embeded can by used for @Embedable class which is not entity and does not has own table. Fields of embedable will by part of owning entity/table
