[SOLVED] Spring Mongo Auditing not working @CreatedDate @CreatedBy

Spring Mongo Auditing not working @CreatedDate @CreatedBy

I am using Spring Mongo Auditing and @CreatedDate @CreatedBy not working but @LastModifiedDate and @LastModifiedBy working fine.

I added @EnableMongoAuditing on a configuration class and also defined the AuditAware.

@Component("securityAuditorAware")
public class SecurityAuditorAware implements AuditorAware<String> {

 @Override
 public Optional<String> getCurrentAuditor() {
  return Optional.ofNullable(SecurityUtils.getUserPrincipal()).map(AuthenticatedUser::getIssuer);
 } 
}

Auditing class is :

@Document
public class Template  {

 @Id
 private UUID id = UUID.randomUUID();

 @CreatedDate
 private Date createdOn;
 @LastModifiedDate
 private Date modifiedOn;
 @CreatedBy
 private String createdBy;
 @LastModifiedBy
 private String modifiedBy;
}

When I save the document it put null in both createdOn and createdBy but the right values in both modifiedOn and modifiedBy

Thanks for the help

Solution

If your Entity does not inheritance Persistable interface, you should define a field which marked by @Version (org.springframework.data.annotation.Version).

@Document
public class Template {

 @Id
 private UUID id = UUID.randomUUID();

 @CreatedDate
 private Date createdOn;
 @LastModifiedDate
 private Date modifiedOn;
 @CreatedBy
 private String createdBy;
 @LastModifiedBy
 private String modifiedBy;
 @Version
 private Integer version;
}

In other side, if your entity inheritance Persistable interface, you should implement logical which to detect the entity never been persisted before.

For more information, you can check two class: PersistentEntityIsNewStrategy and PersistableIsNewStrategy
