使用vo和dto利用springBoot框架写一个酒店房型的增删改查功能

好的，我可以为您提供一些参考代码。首先，需要定义一个RoomTypeVO类和一个RoomTypeDTO类，分别用于前端展示和数据传输。

RoomTypeVO.java：

public class RoomTypeVO {
    private Long id;
    private String name;
    private String description;
    private Double price;
    // getters and setters
}

RoomTypeDTO.java：

public class RoomTypeDTO {
    private Long id;
    private String name;
    private String description;
    private Double price;
    // getters and setters
}

接下来，需要定义一个RoomTypeService接口和一个RoomTypeServiceImpl实现类，用于处理业务逻辑。

RoomTypeService.java：

public interface RoomTypeService {
    List<RoomTypeDTO> getAllRoomTypes();
    RoomTypeDTO getRoomTypeById(Long id);
    void createRoomType(RoomTypeDTO roomTypeDTO);
    void updateRoomType(RoomTypeDTO roomTypeDTO);
    void deleteRoomType(Long id);
}

RoomTypeServiceImpl.java：

@Service
public class RoomTypeServiceImpl implements RoomTypeService {

    @Autowired
    private RoomTypeRepository roomTypeRepository;

    @Override
    public List<RoomTypeDTO> getAllRoomTypes() {
        List<RoomType> roomTypes = roomTypeRepository.findAll();
        return roomTypes.stream().map(this::convertToDTO).collect(Collectors.toList());
    }

    @Override
    public RoomTypeDTO getRoomTypeById(Long id) {
        RoomType roomType = roomTypeRepository.findById(id).orElse(null);
        return convertToDTO(roomType);
    }

    @Override
    public void createRoomType(RoomTypeDTO roomTypeDTO) {
        RoomType roomType = convertToEntity(roomTypeDTO);
        roomTypeRepository.save(roomType);
    }

    @Override
    public void updateRoomType(RoomTypeDTO roomTypeDTO) {
        RoomType roomType = convertToEntity(roomTypeDTO);
        roomTypeRepository.save(roomType);
    }

    @Override
    public void deleteRoomType(Long id) {
        roomTypeRepository.deleteById(id);
    }

    private RoomTypeDTO convertToDTO(RoomType roomType) {
        if (roomType == null) {
            return null;
        }
        RoomTypeDTO roomTypeDTO = new RoomTypeDTO();
        roomTypeDTO.setId(roomType.getId());
        roomTypeDTO.setName(roomType.getName());
        roomTypeDTO.setDescription(roomType.getDescription());
        roomTypeDTO.setPrice(roomType.getPrice());
        return roomTypeDTO;
    }

    private RoomType convertToEntity(RoomTypeDTO roomTypeDTO) {
        if (roomTypeDTO == null) {
            return null;
        }
        RoomType roomType = new RoomType();
        roomType.setId(roomTypeDTO.getId());
        roomType.setName(roomTypeDTO.getName());
        roomType.setDescription(roomTypeDTO.getDescription());
        roomType.setPrice(roomTypeDTO.getPrice());
        return roomType;
    }
}

最后，需要定义一个RoomTypeController类，用于处理HTTP请求。

RoomTypeController.java：

@RestController
@RequestMapping("/room-types")
public class RoomTypeController {

    @Autowired
    private RoomTypeService roomTypeService;

    @GetMapping
    public List<RoomTypeDTO> getAllRoomTypes() {
        return roomTypeService.getAllRoomTypes();
    }

    @GetMapping("/{id}")
    public RoomTypeDTO getRoomTypeById(@PathVariable Long id) {
        return roomTypeService.getRoomTypeById(id);
    }

    @PostMapping
    public void createRoomType(@RequestBody RoomTypeDTO roomTypeDTO) {
        roomTypeService.createRoomType(roomTypeDTO);
    }

    @PutMapping("/{id}")
    public void updateRoomType(@PathVariable Long id, @RequestBody RoomTypeDTO roomTypeDTO) {
        roomTypeDTO.setId(id);
        roomTypeService.updateRoomType(roomTypeDTO);
    }

    @DeleteMapping("/{id}")
    public void deleteRoomType(@PathVariable Long id) {
        roomTypeService.deleteRoomType(id);
    }
}

以上代码是一个简单的酒店房型的增删改查功能的实现，您可以根据实际需求进行修改和扩展。
