패스트캠퍼스 챌린지 3일차

CH 03. 인텔리제이 실습 - To do List 구현하기

 

05. 서비스 코드 구현

 - Service layer : 작성한 repository가 실제로 작성하는 코드를 구현

//TodoService
package org.example.servcie;

import lombok.AllArgsConstructor;
import org.example.model.TodoEntity;
import org.example.model.TodoRequest;
import org.example.repository.TodoRepository;
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;

    public TodoEntity add(TodoRequest request){		//1	todo 리스트 목록에 아이템을 추가
        TodoEntity todoEntity = new TodoEntity();
        todoEntity.setTitle(request.getTitle());
        todoEntity.setOrder(request.getOrder());
        todoEntity.setCompleted(request.getCompleted());
        
        return this.todoRepository.save(todoEntity);
    }

    public TodoEntity searchById(Long id){		//2	todo  리스트 목록 중 특정 아이템을 조회
        return this.todoRepository.findById(id)
                .orElseThrow(()-> new ResponseStatusException(HttpStatus.NOT_FOUND));
    }

    public List<TodoEntity> serachAll() {		//3	todo 리스트 전체 목록을 조회
        return this.todoRepository.findAll();
    }

    public TodoEntity updateById(Long id, TodoRequest request){		
    											//4	todo 리스트 목록 중 특정 아이템을 수정
        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);

    }
    public void deleteById(Long id){	//5	todo 리스트 목록 중 특정 아이템을 삭제
        this.todoRepository.deleteById(id);

    }

    public void deleteAll(){	//6	todo 리스트 전체 목록을 삭제
        this.todoRepository.deleteAll();
    }
}

06. 컨트롤러 구현

- Control : Server에 들어오는 Request를 처리 및 Response

package org.example.controller;

import lombok.AllArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.example.model.TodoEntity;
import org.example.model.TodoRequest;
import org.example.model.TodoResponse;
import org.example.service.TodoService;
import org.springframework.http.ResponseEntity;
import org.springframework.util.ObjectUtils;
import org.springframework.web.bind.annotation.*;

import java.util.List;
import java.util.stream.Collectors;

@Slf4j
@CrossOrigin
@AllArgsConstructor
@RestController
@RequestMapping("/")
public class TodoController {

    private final TodoService todoService;

    @PostMapping
    public ResponseEntity<TodoResponse> create(@RequestBody TodoRequest request) {
        log.info("CREATE");

        if (ObjectUtils.isEmpty(request.getTitle()))
            return ResponseEntity.badRequest().build();

        if (ObjectUtils.isEmpty(request.getOrder()))
            request.setOrder(0L);

        if (ObjectUtils.isEmpty(request.getCompleted()))
            request.setCompleted(false);

        TodoEntity result = this.todoService.add(request);
        
        return ResponseEntity.ok(new TodoResponse(result));
    }

    @GetMapping
    public ResponseEntity<List<TodoResponse>> readAll() {
        log.info("READ ALL");
        List<TodoEntity> result = this.todoService.searchAll();
        List<TodoResponse> response = result.stream().map(TodoResponse::new).collect(Collectors.toList());
        
        return ResponseEntity.ok(response);
    }

    @GetMapping("{id}")
    public ResponseEntity<TodoResponse> readOne(@PathVariable Long id) {
        log.info("READ");
        TodoEntity result = this.todoService.searchById(id);
        
        return ResponseEntity.ok(new TodoResponse(result));
    }

    @PatchMapping("{id}")
    public ResponseEntity<TodoResponse> update(@PathVariable Long id, @RequestBody TodoRequest request) {
        log.info("UPDATE");
        TodoEntity result = this.todoService.updateById(id, request);
       
       return ResponseEntity.ok(new TodoResponse(result));
    }

    @DeleteMapping
    public ResponseEntity<?> deleteAll() {
        log.info("DELETE ALL");
        this.todoService.deleteAll();
        
        return ResponseEntity.ok().build();
    }

    @DeleteMapping("{id}")
    public ResponseEntity<?> deleteOne(@PathVariable Long id) {
        log.info("DELETE");
        this.todoService.deleteById(id);
        
        return ResponseEntity.ok().build();
    }
}
