[Spring Jpa] @CreatedDate, @LastModifiedDate null

1. Application 파일에 @EnableJpaAuditing 추가

@SpringBootApplication
@EnableJpaAuditing

public class BoardApplication {

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

 

2. @CreatedDate, @LastModifiedDate 선언한 entity에 위에 @EntityListeners(AuditingEntityListener.class) 선언

@MappedSuperclass
@EntityListeners(value = { AuditingEntityListener.class })
@Getter
abstract class BaseEntity {

    @CreatedDate
    private LocalDateTime regDate;

    @LastModifiedDate
    private LocalDateTime modDate;

}

 

하면 해결됩니다!
