Hibernate envers: RelationTargetAuditMode.NOT_AUDITED vs @NotAudited

Question

I try to audit an entity but I don't want to audit its relationships. If I put @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED) in @ManyToOne relations, this works and I don't have any exception, but when I try to use the same annotation in a @onetomany with the param mappedby defined, I have an exception that says me that I have to audit the other entity.

Example:

@Table(name = "OWNERS")
@Entity
@EntityListeners(AuditingEntityListener.class)
@Audited
public class Owner {
...
  @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)
  @ManyToOne(fetch=FetchType.LAZY)
  private User user;
...
  @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)
  @OneToMany(cascade = CascadeType.ALL, mappedBy = "owner" )
  private Set<Pet> pets = new HashSet<Pet>();
...
}

Answer 1

When you use @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED) you are telling hibernate not to audit this entity but audit the relation so you hibernate will save the id of the referenced entity. Thats why Pet must be an @Audited entity.

If you do not want to store the relation at all you need to use @NotAudited

Answer 2

Well, I think you have two options here:

1. Actually audit the entity Pet , if applicable;

2. Use the annotation @NotAudited instead of @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED) . Think about it, The audit table for Owner doesn't have to persist the Pet 's associated. If it does, use option 1.

Hope it helps!
