Auditing

• 등록일
• 수정일
• 등록자
• 수정자
  위 정보를 등록하기 위해 사용해준다.

@EnableJpaAuditing을 추가해준 뒤에 등록자, 수정자를 처리해주는 AuditorAware을 스프링 빈으로 등록해준다.

@SpringBootApplication
@EnableJpaAuditing
public class SpringbootDeveloperApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootDeveloperApplication.class, args);
    }

    @Bean
    public AuditorAware<Long> auditorProvider() {
        return new AuditorAwareImpl();
    }
}

public class AuditorAwareImpl implements AuditorAware<Long> {

    @Override
    public Optional<Long> getCurrentAuditor() {
        // security 작성 후 구현
        return null;
    }
}

@EntityListeners(AuditingEntityListener.class)
@MappedSuperclass
@Getter
public class BaseTimeEntity {
    
    @CreatedDate
    @Column(updatable = false)
    private LocalDateTime createdDate;
    
    @LastModifiedDate
    private LocalDateTime lastModifiedDate;
}

@EntityListeners(AuditingEntityListener.class)
@MappedSuperclass
@Getter
public class BaseEntity extends BaseTimeEntity {

    @CreatedBy
