[패스트캠퍼스 수강 후기] 자바 인강 100% 환급 챌린지 46회차 미션

11.11. 레이어 분리 - 1 ~ 12. 12.  레이어 분리 - 2

==> 서비스 만들기( 복잡한 로직 처리: django view 역할 ), menu , item 만들기했음.

Layer Architecture 에 대해서 이야기 했던 지난시간.. (domain layer, ui layer, application layer)

우리는 ui layer (controller -> interfaces), domain layer(user, restaurant->domain) 을 배우고 직접 구현까지 했었다.

이번 시간에 application layer 에 대해 학습하고 구현해볼까 한다.-> 서비스 -> 복잡한 로직을 처리해준다.

 

menu., item

package kr.co.fastcampus.eatgo.domain;

import com.fasterxml.jackson.annotation.JsonInclude;
import lombok.*;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Transient;

@Entity
@Getter
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class MenuItem {

    @Id
    @GeneratedValue
    private Long id;

    @Setter
    private Long restaurantId;

    private String name;

    @Transient
    @JsonInclude(JsonInclude.Include.NON_DEFAULT)
    private boolean destroy;
}

package kr.co.fastcampus.eatgo.application;

import kr.co.fastcampus.eatgo.domain.MenuItem;
import kr.co.fastcampus.eatgo.domain.MenuItemRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import javax.transaction.Transactional;
import java.util.List;

@Service
@Transactional
public class MenuItemService {

    private MenuItemRepository menuItemRepository;

    @Autowired
    public MenuItemService(MenuItemRepository menuItemRepository) {
        this.menuItemRepository = menuItemRepository;
    }

    public List<MenuItem> getMenuItems(Long restaurantId) {
        return menuItemRepository.findAllByRestaurantId(restaurantId);
    }

    public void bulkUpdate(Long restaurantId, List<MenuItem> menuItems) {
        for (MenuItem menuItem : menuItems) {
            update(restaurantId, menuItem);
        }
    }

    private void update(Long restaurantId, MenuItem menuItem) {
        if (menuItem.isDestroy()) {
            menuItemRepository.deleteById(menuItem.getId());
            return;
        }

        menuItem.setRestaurantId(restaurantId);
        menuItemRepository.save(menuItem);
    }

}

아직까지 tdd 가 엄청난걸 모르겠는게 컴파일시간이 배로들것 같다..

어려운 이야기

 

 

서비스는

@Service 라는 어노테이션을 지정해주면, 스프링이 알아서 관리 해준다.

@Before: 모든 테스트 전에 실행하기
