혼자 개인 프로젝트를 진행하는데 궁금증이 생겨 질문드립니다.
@modelattribute를 사용해서 바인딩하려면 dto에 setter가 구현이 되어있어야 하는걸로 알고있습니다.
그런데 혼자 프로젝트를 끄적이다가 한dto는 setter를 구현안했음에도 바인딩이 되길래 궁금증이 생겨 질문드려요!
--------fundingDto를 입력받는 폼------------

fundingDto
@Getter
@Builder
@AllArgsConstructor
public class FundingDto {
private Long id;
private String restaurantName;
private String menu;
private String information;
private String introduction;
private String notice;
private Integer discountPrice;
private Integer price;
private Integer minFundingCount;
private Integer maxFundingCount;
private Integer nowFundingCount;
private MultipartFile mainImage;
private List<MultipartFile> imageFiles;
private List<Image> imageList;
@Enumerated(EnumType.STRING)
private FundingStatus fundingStatus;
@DateTimeFormat(pattern = "yyyy-MM-dd'T'HH:mm")
private LocalDateTime startDate;
@DateTimeFormat(pattern = "yyyy-MM-dd'T'HH:mm")
private LocalDateTime endDate;
public void setMainImage(MultipartFile mainImage) {
this.mainImage = mainImage;
}
}
다른 dto는 @setter를 달아주지않으면 null이 바인딩 되는데 이 객체는 왜 바인딩이 성공하는지 잘 모르겠어요..
그리고 한가지 더 질문이 있는데 @modelattribute 를 사용함에 있어 @Setter를 사용하지 않고는 사용이 불가능한가요?
@Setter를 되도록 사용하지 않는게 좋다고 들어가지고 질문드립니다.
