I am using Hibernate Envar for Audit purpose.
Here is my code and configuration
hibernate.cfg.xml file configuration
<!-- Audit -->
<listener class="org.hibernate.envers.event.AuditEventListener" type="post-insert"/>
<listener class="org.hibernate.envers.event.AuditEventListener" type="post-update"/>
<listener class="org.hibernate.envers.event.AuditEventListener" type="post-delete"/>
<listener class="org.hibernate.envers.event.AuditEventListener" type="pre-collection-update"/>
<listener class="org.hibernate.envers.event.AuditEventListener" type="pre-collection-remove"/>
<listener class="org.hibernate.envers.event.AuditEventListener" type="post-collection-recreate"/>
One Sample Entity Annoted with @Audited
@Entity
@Table(name = "Users")
@Audited
public class User extends GenericDomain implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(length=100)
private String name;
@Column(length=60)
private String username;
@Column(length=130)
private String password;
// Getter and setter with more fields
}
I have created a RevistionEntity to log audit for logged in user, for whom we are logging audit as
@Entity
@Table(name = "REVISIONS")
@RevisionEntity(CustomRevisionListener.class)
public class CustomRevisionEntity {
@Id
@GeneratedValue
@RevisionNumber
private int id;
@RevisionTimestamp
private long audit_timestamp;
private String username;
private Long userid;
// Getter and Setter
}
Here is my listener class
public class CustomRevisionListener implements RevisionListener {
public void newRevision(Object revisionEntity) {
CustomRevisionEntity revision = (CustomRevisionEntity) revisionEntity;
revision.setUsername("username"); //for testing
}
}
For Insert/Delete it works fine.
But for Update query it is giving following exception as
[ERROR] [http-8080-1 06:05:26] (JDBCExceptionReporter.java:logExceptions:101) Duplicate entry '1085-3' for key 1

Here is my generic update code for all entities
public E update(E entity) {
getSession().update(entity);
return entity;
}
Unfortunately without the full stacktrace and the SQL definition of the tables, its hard to say whats happening here. These are the things I would check:
Constraints/PK on the audit tables? – is it possible your primary key is missing the revision number AND revision type – I had this occur because an update and a delete happened in the same session for a particular entity (I think it had something to do with a Cascade operation, but I cannot recall now), and I was expecting the revision number + PK of the entity table to be enough to uniquely identify each row in the audit tables.
Remember that by default deleted entities only contain the revision number, revision type, and the ID/PK of the original entity. If you have a NOT NULL constraint on the audit table, that could cause the failure. You can work around that by setting the
org.hibernate.envers.store_data_at_deleteproperty totrue.
