How To Setup Spring Data JPA Auditing
Description: Auditing is useful for maintaining history records. This can later help us in tracking user activities.
Key points:
- create an
abstractbase entity (e.g.,BaseEntity) and annotate it with@MappedSuperclassand@EntityListeners({AuditingEntityListener.class}) - in this base entity, add the following fields that will be automatically persisted:
-@CreatedDate protected LocalDateTime created;
-@LastModifiedDate protected LocalDateTime lastModified;
-@CreatedBy protected U createdBy;
-@LastModifiedBy protected U lastModifiedBy; - enable auditing via
@EnableJpaAuditing(auditorAwareRef = "auditorAware") - provide an implementation for
AuditorAware(this is needed for persisting the user that performed the modification; use Spring Security to return the currently logged-in user) - expose this implementation via
@Bean - entites that should be audited should extend the base entity
- store the date-time in database in UTC
