[JAVA] 인텔리제이 To - do List_레파지터리 & 서비스 구현

레파지터리 구현

• TodoRepository.java 생성

import org.example.model.TodoEntity;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface TodoRepository extends JpaRepository<TodoEntity, Long> {
}

• TodoServerApplication.java 생성

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class TodoServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(TodoServerApplication.class, args);
    }
}

 

서비스 구현

• TodoService.java

import lombok.AllArgsConstructor;
import org.example.Repository.TodoRepository;
import org.example.model.TodoEntity;
import org.example.model.TodoRequest;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Service;
import org.springframework.web.server.ResponseStatusException;

import java.util.List;

@Service
@AllArgsConstructor
public class TodoService {
    private  final TodoRepository todoRepository;

    //todo 리스트 목록에 아이템 추가
    public TodoEntity add(TodoRequest request){
        TodoEntity todoEntity = new TodoEntity();
        todoEntity.setTitle(request.getTitle());
        todoEntity.setOrder(request.getOrder());
        todoEntity.setCompleted(request.getCompleted());
        return  this.todoRepository.save(todoEntity);
    }
    //특정 아이템 조회
    public TodoEntity searchById(Long id){
        return this.todoRepository.findById(id).orElseThrow(() -> new ResponseStatusException(HttpStatus.NOT_FOUND));
    }
    //전체목록 조회
    public List<TodoEntity> searchAll(){
        return this.todoRepository.findAll();
    }
    //특정 아이템 수정
    public TodoEntity updateById(Long id, TodoRequest request){
        TodoEntity todoEntity = this.searchById(id);
        if(request.getTitle() != null){
            todoEntity.setTitle(request.getTitle());
        }
    if(request.getOrder() != null){
        todoEntity.setOrder(request.getOrder());
    }
    if(request.getCompleted() != null){
        todoEntity.setCompleted(request.getCompleted());
    }
        return this.todoRepository.save(todoEntity);
    }
    //특정아이템 삭제
    public  void deleteById(Long id){
		this.todoRepository.deleteById(id);
    }
    //전체 목록 삭제
   	public void deleteAll(){
		this.todoRepository.deleteAll();
    }
}
