프로잭트 기능구현을 완료하고 오늘 각자 추가 기능 및 최적화 선택하여 진행했다

혼자 point 추가 기능을 구현했는데 전 프로잭트에서  CRUD 열라해서 그런지

막힘 없이 진행했는데 UserId 를 PK 로 사용해서 진행하다가 만들다 보니

굳이 이걸 Id 로 해야되나 의문이 생겨 다 완성한 코드를 다시 갈아 엎었다 ..

 

PointController

 

@RestController
@RequiredArgsConstructor
@RequestMapping( "/point")
public class PointController {
    private final PointServiceImpl pointService;

    @GetMapping("/inquir")
    public ResponseEntity<PointResponse> getPoint(@AuthenticationPrincipal UserDetailsImpl userDetails) {
        String username = userDetails.getUsername();
        PointResponse response = pointService.getPoint(username);
        return ResponseEntity.ok().body(response);
    }

    @PostMapping("/buygoods/{productId}")
    public ResponseEntity<PointResponse> BuyGoods(@PathVariable Long productId, @AuthenticationPrincipal UserDetailsImpl userDetails) {
        String username = userDetails.getUsername();
        PointResponse pointBuyGoods = pointService.pointBuyGoods(username, productId);
        return ResponseEntity.ok().body(pointBuyGoods);
    }

    @PostMapping("/admin")
    public ResponseEntity<AdminGivePresentResponse> adminGivePresent(@RequestBody AdminGivePresentRequest request, @AuthenticationPrincipal UserDetailsImpl userDetails) {
        User user = userDetails.getUser();
        AdminGivePresentResponse adminGivePresentResponse = pointService.adminGivePresent(request, user);
        return ResponseEntity.ok().body(adminGivePresentResponse);
    }
}
