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 abstract base entity (e.g., BaseEntity) and annotate it with @MappedSuperclass and @EntityListeners({AuditingEntityListener.class})
- in this base entity, add the following fields that will be automatically persisted:
- @CreatedDate protected LocalDateTime createdAt;
-@LastModifiedDate protected LocalDateTime updatedAt;
-@CreatedBy protected U createdBy;
-@LastModifiedBy protected U modifiedBy;
- 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
