@CreatedBy나 @LastModifedBy 설정에서 문제가 생기는 것 같습니다.

@Entity
@Getter
@NoArgsConstructor
@ToString(of = {"id", "name", "price"})
public class Item extends BaseEntity {
    @Id @GeneratedValue
    @Column(name = "item_id")
    private Long id;

    private String name;
    private int price;

    private String title;
    private String filePath;

    public Item(String name, int price) {
        this(name, price, null, null);
    }

    public Item(String name, int price, String title, String filePath) {
        this.name = name;
        this.price = price;
        this.title = title;
        this.filePath = filePath;
    }
}

 

@Profile("local")
@Component
@RequiredArgsConstructor
public class InitItem {

    private final InitItemService initItemService;

    @PostConstruct
    public void init() {
        initItemService.init();
    }

    @Component
    @RequiredArgsConstructor
    static class InitItemService {

        private final ItemRepository itemRepository;

        @Transactional
        public void init() {
            for (int i = 0; i < 10; i++) {
                itemRepository.save(
                        new Item("cat's tower" + i, (i + 1) * 50,
                                "Cat's Tower v." + i, "img/catTower" + i + ".jpg"));
            }
        }
    }

 

@EntityListeners(AuditingEntityListener.class)
@MappedSuperclass
@Getter
@ToString(of = {"createdDate", "lastModifiedDate"})
public class BaseTimeEntity {

    @CreatedDate
    @Column(updatable = false)
    private LocalDateTime createdDate;

    @LastModifiedDate
    private LocalDateTime lastModifiedDate;
}

 

@EntityListeners(AuditingEntityListener.class)
@MappedSuperclass
@Getter
@ToString(of = {"createdBy", "lastModifiedBy"}, callSuper = true)
public class BaseEntity extends BaseTimeEntity {
    @CreatedBy
    @Column(updatable = false)
    private LocalDateTime createdBy;
    @LastModifiedBy
    private LocalDateTime lastModifiedBy;
}

 

@SpringBootApplication
@EnableJpaAuditing
public class ShoppingmallApplication {

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

   @Bean
   public AuditorAware<String> auditorAware() {
      return () -> Optional.of(UUID.randomUUID().toString());
   }

}

 

public class Item extends BaseTimeEntity를 하면 

즉 @CreatedDate, @LastModifiedDate까지는 잘 작동하는데 

 

@Bean을 설정 후 

public class Item extends BaseEntity로 바꾸면 

Cannot cast java.lang.String to java.time.LocalDateTime 오류가 터져서 

검색으로 조금 알아봤더니 ,

mysql사용시 liquibase-core v.3.10.3에서 발생하는 문제이고

v.4.3.1로 변경하면 된다는 글을 찾았는데 

프로젝트 내에서 liquibase는 없고 

 

또, 다른 글에서는 number타입을 String타입으로 형변환 할 때 나타나는 오류라고 하는데 

허접한 시도들을 해보았으나, 

결국 저 코드에서 어떻게 손대야 될 지 모르겠어서 질문올립니다 :[

안녕하세요. relate16님, 공식 서포터즈 David입니다.

.

올려주신 코드 확인했습니다. 
1. @CreatedDate, @LastModifiedDate와 @CreatedBy, @LastModifiedBy를 어떤 타입에 적용하셔야 하는지에 대해서 찾아보시면 쉽게 해결하실 수 있습니다.

2. 죄송하지만 질문 안내에 있는 것 처럼 학습에 관련된 질문을 올려주시길 부탁드립니다. 마음으로는 하나하나 상세히 도움을 드리고 싶지만, 하루에도 수 많은 분들이 질문을 올려주십니다. 그래서 학습과 관련된 질문에 초점을 맞추는 것이 맞다 생각합니다. 다시 한 번 이해를 부탁드립니다.

.
감사합니다.

네 알겠습니다. :)

다른 프로젝트이긴 하지만

학습 내용을 적용한 것에 대한 질문이라 올려도 되는 지 알았습니다.  죄송합니다  :(

항상 고생많으십니다 ㅠ

좋은 하루되세요 :)

String으로 받으셔야 하는데, LocalDateTime으로 받으셔서 문제가 생긴것 같네요.

@LastModifiedBy
    private LocalDateTime lastModifiedBy

안녕하세요. relate16님

H2 데이터베이스에서 동작하도록 변경해주세요.

그리고 전체 프로젝트를 압축해서 구글 드라이브로 공유해서 링크를 남겨주세요.

구글 드라이브 업로드 방법은 다음을 참고해주세요.

https://bit.ly/3fX6ygx

 

주의: 업로드시 링크에 있는 권한 문제 꼭 확인해주세요

 

추가로 다음 내용도 코멘트 부탁드립니다.

1. 실행 방법을 알려주세요.

2. 어떻게 문제를 확인할 수 있는지 자세한 설명을 남겨주세요.

감사합니다.

public class Item extends BaseTimeEntity를 하면 

item을 DB에 등록할 때(애플리케이션 실행시, InitItem 프로파일 클래스로 실행됩니다.),

즉 @CreatedDate, @LastModifiedDate까지는 잘 작동하는데 

 

public class Item extends BaseEntity로 바꾸면 

Cannot cast java.lang.String to java.time.LocalDateTime 오류가 터집니다.

 

매번 감사합니다
