  • ✅ Auditing introduction, very beginner-friendly

  • ⛔ Since beginner-friendly, the database structure could be introduced (especially how auditing stores additional data)

"The queries must flow"

Spring Data JPA has a pre-baked JpaRepository that extends PagingAndSortingRepository from Spring Data.

For debugging, enable spring.jpa.show-sql=true and logging.level.org.springframework.data=TRACE.

Having a 1:N relationship between Manager and Employee entities using Spring Data JPA:

  • List<Employee> findByNameContainingIgnoreCase(String partialName) for full-text search.

  • List<Employee> findByManagerName(String managerName) query navigates across relationships.

Use @EnableJpaAuditing and register @EntityListeners(AuditingEntityListener.class) on the Employee object to enable auditing through @CreatedDate and @LastModifiedDate.
