JPA 기본 설정 완성 후

소스 작업 전 테스트 소스를 먼저 만들어보자

Base도메인 설정

@MappedSuperclass
@EntityListeners(value = { AuditingEntityListener.class })
//spring jpa AuditingEntityListener 에서 가져옴
// 해당 클래스가 적용되면 엔티티가 데이터베이스에 추가 / 변경될 때 자동으로 시간 값을 저장
// AuditingEntityListener 활성화 하기 위해 프로젝트 설정에 @EnableJpaAuditing 추가 해야함
@Getter
public class BaseEntity {

    @CreatedDate
    @Column(name = "regdate", updatable = false)
    private LocalDateTime regDate;

    @LastModifiedDate
    @Column(name = "moddate")
    private LocalDateTime modDate;


}

repository 인터페이스 설정

// spring jpa data 이용할 때 JpaRepository 인터페이스를 이용해서
// 인터페이스 선언만으로 데이터 베이스 기본 작업 CRUD 와 페이징 처리가 가능하다.

public interface BoardRepository extends JpaRepository<Board, Long> {}

실제 사용 Board 도메인 설정

@Entity
@Getter
@Builder
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class Board extends BaseEntity {
    //BaseEntity 에서 전체 적용 되는 데이터베이스 값을 가져온다

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    // GenerationType.IDENTITY 데이터 베이스에 위임-auto_increment (mysql/maria)
    private Long bno;

    @Column(length = 500 , nullable = false) //컬럼 길이와 null  허용 여부
    private String title;

    @Column(length = 2000 , nullable = false)
    private String content;

    @Column(length = 50 , nullable = false)
    private String writer;

}

인서트 테스트 코드 작성 후 RUN ~~~

@SpringBootTest
@Log4j2
public class BoardRepositoryTest {

    @Autowired
    private BoardRepository boardRepository;

    @Test
    public void testInsert(){
        IntStream.rangeClosed(1,100).forEach( i ->{
            Board board = Board.builder()
                    .title("제목 ... "+i)
                    .content("내용 ... "+ i)
                    .writer("user"+(i%10))
                    .build();
            Board result = boardRepository.save(board);
            log.info("BNO : " + result.getBno());
        });
    }
}

위 코드를 GPT가 분석해 줌

위의 자바 코드는 빌더 패턴을 이용하여 board 객체를 생성하는 코드입니다.
빌더 패턴은 복잡한 객체를 생성할 때, 객체의 생성과 표현을 분리하여 객체를 생성하는 디자인 패턴입니다. 이 코드에서는 빌더를 사용하여 제목, 내용 및 작성자가 있는 게시판 객체를 생성합니다.

빌더는 메소드 호출 체인으로 사용되고 있습니다. title() 메소드는 i 변수의 값과 문자열을 연결하여 게시판의 제목을 설정합니다. content() 메소드는 i 변수의 값과 문자열을 연결하여 게시판의 내용을 설정합니다. writer() 메소드는 i를 10으로 나눈 나머지와 문자열을 연결하여 게시판의 작성자를 설정합니다.

마지막으로 build() 메소드가 호출되어 빌더가 설정한 값으로 새로운 board 객체가 생성되고 반환됩니다.

실제 스프링 띄우면서 JPA 테이블 생성하고 인서트 까지 이상없이 실행
