Issue
Given the following base class...
...
import org.hibernate.envers.Audited;
@Audited
@Entity
@Table(
name = "account",
indexes = {
@Index(name = "account_currency_id_idx", columnList = "currency_id")
})
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "account_type")
public class Account {
@Id
@GeneratedValue
@Setter(AccessLevel.NONE)
@NotNull
private Long id;
@Audited
@LastModifiedDate
@Column(name = "last_modified_date_time")
@Setter(AccessLevel.NONE)
private LocalDateTime lastModifiedDateTime;
@Audited
@LastModifiedBy
@Setter(AccessLevel.NONE)
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "last_modified_by_user_id", referencedColumnName = "id")
@Audited(targetAuditMode = NOT_AUDITED)
private User lastModifiedByUser;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "currency_id", referencedColumnName = "id")
@ApiFieldMappingProperty("currencyId")
@Audited(targetAuditMode = NOT_AUDITED)
private Currency currency;
@NotNull
@Column(name = "open_date", nullable = false)
private LocalDate openDate;
@Column(name = "close_date")
private LocalDate closeDate;
...
}
... I defined two derived classes with no member fields but with a discriminator value that let me differentiate account types automatically. Here's the first derived class...
...
@Entity(name = "domestic_account")
@DiscriminatorValue("DOMESTIC")
public DomesticAccount extends Account {
}
... and here's the second one:
@Entity(name = "offshore_account")
@DiscriminatorValue("OFFSHORE")
public OffshoreAccount extends Account {
}
In the code I never use class Account directly; instead, I always instantiate (and save) either a DomesticAccount or a OffshoreAccount.
The problem is that even if I enabled auditing with @Audited, changes get never logged and table ACCOUNT_AUD remains empty.
Am I missing something? Any help is really appreciated.
Solution
In the end, annotating the derived classes with @Audited fixed the issue:
...
import org.hibernate.envers.Audited;
@Audited
@Entity(name = "domestic_account")
@DiscriminatorValue("DOMESTIC")
public DomesticAccount extends Account {
}
Also many thanks to Christian Beikov for his support.
