java.lang.IllegalStateException: No primary or default constructor found for class com.coco.domain.BoardVO

기본 생성자를 찾을 수 없다는 에러다.
그래서 VO클래스에 Lombok의 @NoArgsConstructor를 이용하여 기본 생성자를 만들어줬더니,
@Builder에 빨간 줄이 생기면서 The constructor BoardVO(Long, String, String, String, Date, Date) is undefined라는 메세지가 나왔다.
@Builder를 쓰면 모든 요소가 포함된 생성자가 함께 생성되는데, 거기다가 @NoArgs.....를 붙이면 그 생성자가 기본 생성자로 바뀐다. 따라서, 빌더에 꼭 필요한 생성자가 사라졌다는 에러 메세지를 출력하는 것이다.
@AllArgsConstructor도 함께 붙여주면 해결된다.

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class BoardVO {
    private Long bno;
    private String title;
    private String content;
    private String writer;
    private Date regdate;
    private Date moddate;
}
