// Use SPRING REST CONTROLLER annotation
@RestController
@RequestMapping("/api/reservations")
public class ReservationApiController {
  private final ReservationRepository reservationRepository; // Could be a service as well
  public ReservationApiController(ReservationRepository reservationRepository) {
    this.reservationRepository = reservationRepository;
  }

  @GetMapping
  public List<Reservation> getAllReservations(@RequestParam(value="date", required = false)String dateString){
    if(StringUtils.isNotBlank(dateString)){
      Date date = new Date(new java.util.Date().getTime());
      return this.reservationRepository.findAllByReservationDate(date);
    }
    return this.reservationRepository.findAll();
  }

  @PostMapping
  @ResponseStatus(HttpStatus.CREATED)
  public Reservation addReservation(@RequestBody Reservation reservation){
    return this.reservationRepository.save(reservation);
  }

  @GetMapping("/{id}")
  public Reservation getReservation(@PathVariable("id")long id){
    Optional<Reservation> reservation = this.reservationRepository.findById(id);
    if (reservation.isEmpty()){
      throw new NotFoundException("reservation not found with id: " + id);
    }
    return reservation.get();
  }

  @PutMapping("/{id}")

    if (id != reservation.getId()){
      throw new BadRequestException("id on path must match body");
    }
    return reservationRepository.save(reservation);
  }

  @DeleteMapping("/{id}")
  @ResponseStatus(HttpStatus.RESET_CONTENT)
  public void deleteReservation(@PathVariable("id")long id){
    this.reservationRepository.deleteById(id);
  }
