스프링 날짜 자동 적용 위한 jpaAuditing 적용 방법

 

1. @EnableJpaAuditing, @Configuration 어노테이션 붙은 configuration 클래스 생성

@EnableJpaAuditing
@Configuration
public class JpaConfig {
}

 

2. 날짜 칼럼 가지는 추상 baseEntity 클래스 생성

@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public abstract class BaseEntity {
    @CreatedDate
    @Column(updatable = false, nullable = false)
    private LocalDateTime createdAt;
    @LastModifiedDate
    private LocalDateTime modifiedAt;
}

 

3. 아래 예시 entity 처럼 생성한 추상 BaseEntity 상속받으면 적용 됨

@Getter
@Setter
@ToString
@Entity
@Table(name = "booking")
public class BookingEntity extends BaseEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY) // 기본 키 생성을 DB에 위임합니다. (AUTO_INCREMENT)
    private Integer bookingSeq;
    private Integer passSeq;
    private String userId;

    @Enumerated(EnumType.STRING)
    private BookingStatus status;
    private boolean usedPass;
    private boolean attended;

    private LocalDateTime startedAt;
    private LocalDateTime endedAt;
    private LocalDateTime cancelledAt;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "userId", insertable = false, updatable = false)
    private UserEntity userEntity;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "passSeq", insertable = false, updatable = false)
    private PassEntity passEntity;

    // endedAt 기준, yyyy-MM-HH 00:00:00
    public LocalDateTime getStatisticsAt() {
        return this.endedAt.withHour(0).withMinute(0).withSecond(0).withNano(0);
    }

}
