Review Entity
@Entity
@NoArgsConstructor
@Getter
public class Review {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String content;
@ManyToOne
@JoinColumn(name = "item_id")
private Item item;
@ManyToOne
@JoinColumn(name = "member_id")
private Member member;
@Builder
public Review(Long id, String content, Item item, Member member){
this.id = id;
this.content = content;
this.item = item;
this.member = member;
}
}리뷰엔티티에는 해당 아이템, 리뷰 작성자를 다대일 매핑하였다.
ReviewDto 작성
@Data
public class ReviewDto {
private String content;
private Item item;
private Member member;
public Review toEntity(){
return Review.builder()
.content(content)
.item(item)
.member(member)
.build();
}
}ReviewRepository 작성
public interface ReviewRepository extends JpaRepository<Review, Long> {
List<Review> findByItem_Id(Long id);
}아이템의 리뷰 리스트를 받아오기위해 findByItem_Id를 작성했다.
ReviewService 작성
ReviewService
public interface ReviewService {
List<Review> FindItemId(Long id);
void create(ReviewDto reviewDto, Long id, Principal principal);
}ReviewServiceImpl
@Service
@RequiredArgsConstructor
public class ReviewServiceImpl implements ReviewService {
private final ReviewRepository reviewRepository;
private final MemberRepository memberRepository;
private final ItemRepository itemRepository;
@Override
public List<Review> FindItemId(Long id) {
return reviewRepository.findByItem_Id(id);
}
@Override
public void create(ReviewDto reviewDto, Long id, Principal principal) {
Item item = itemRepository.findById(id).get();
Member member = memberRepository.findByEmail(principal.getName());
reviewDto.setMember(member);
reviewDto.setItem(item);
reviewRepository.save(reviewDto.toEntity());
}
}리뷰를 작성할때 create메서드를 이용하는데
각각 item Id와 Principal.getName()으로 member Email을 이용해서 아이템과 멤버 객체를 추가해준뒤 save한다.
ItemController 추가
@GetMapping("/detail/{id}")
public String item_detail(Model model, @PathVariable Long id){
model.addAttribute("item", itemService.itemFindId(id));
model.addAttribute("reviews", reviewService.FindItemId(id));
return "item/detail";
}
@PostMapping("/review_reg/{id}")
public String review_reg(@ModelAttribute ReviewDto reviewDto,
@PathVariable Long id,
Principal principal){
reviewService.create(reviewDto, id, principal);
return "redirect:/item/detail/"+id;
}
