Hibernate Enver - Listening for only one change in referenced class - spring-boot

Question

I have an entity as shown below that I am auditing using Hibernate Enver
#Entity
#Table(name = "watch_item")
#Audited
public class WatchItemEntity implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Type(type = "uuid-char")
#Column(name = "watch_item_id", columnDefinition = "VARCHAR(36)")
private UUID watchItemId;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "watch_model_id")
private WatchModelEntity watchModel;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "private_user_id")
private PrivateUserEntity privateUser;
private String serialNumber;
private Integer productionYear;
private String generalCondition;
private Boolean isMovementFullyFunctional;
private Boolean isInOriginalCondition;
private String comment;
private Boolean isProofOfPurchaseAvailable;
private String country;
private Boolean isCustomsDeclared;
private Boolean hasPaper;
private Boolean hasBox;
private String otherAccessories;
#CreatedDate private LocalDateTime createdDate;
#LastModifiedDate private LocalDateTime modifiedDate;
private String lastServiceProvider;
private LocalDate lastServiceDate;
private BigDecimal lastServiceCost;
private BigDecimal purchasedPrice;
private LocalDate purchasedOn;
...
}
As you can see, it has a PrivateUserEntity field. I want Hibernate Envers to record a change when the privateUser changes (and not record changes in PrivateUserEntity that correspond to the privateUser). However, I don't want to create a Private_User_Aud table. To give some context, a WatchItem can only be owned by one PrivateUser and hence, when the PrivateUser field changes, that means that the WatchItem's owner changed. The entity can be seen below
#Entity
#Table(name = "private_user")
public class PrivateUserEntity implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Type(type = "uuid-char")
#Column(name = "private_user_id", columnDefinition = "VARCHAR(36)")
private UUID privateUserId;
#OneToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "user_id")
private UserEntity user;
#LastModifiedDate private LocalDate modifiedDate;
private String title;
private String firstName;
private String lastName;
private String phone;
private LocalDate dateOfBirth;
private String email;
private String gender;
private String nationality;
private String residencyPermitType;
private LocalDate residencyPermitValidSince;
private String preferredLanguage;
...
}
Is this possible? And if so, how?

Answer 1

You can disable audit for it, doesn't work?
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "private_user_id")
#NotAudited
private PrivateUserEntity privateUser;
