EventResource 객체를 생성하지 않고 EntityModel 객체를 받아와서 처리했습니다.

Question

소스를 공유합니다. @PostMapping public ResponseEntity createEvent(@RequestBody @Valid EventDto event, Errors errors) { if(errors.hasErrors()) { return ResponseEntity.badRequest().body(errors); } eventValidator.validate(event, errors); if(errors.hasErrors()) { return ResponseEntity.badRequest().body(errors); } Event newEvent = eventRepository.save(modelMapper.map(event, Event.class)); Integer eventId = newEvent.getId(); newEvent.update(); WebMvcLinkBuilder selfLinkBuilder = linkTo(EventController.class).slash(eventId); URI createdUri = selfLinkBuilder.toUri(); EntityModel eventResource = EntityModel.of(newEvent); eventResource.add(linkTo(EventController.class).slash(eventId).withSelfRel()); eventResource.add(linkTo(EventController.class).withRel("query-events")); eventResource.add(selfLinkBuilder.withRel("update-event")); return ResponseEntity.created(createdUri).body(eventResource); }

혹은 아래와 같이 처리하기도 하였습니다. @PostMapping public ResponseEntity createEvent(@RequestBody @Valid EventDto event, Errors errors) { if(errors.hasErrors()) { return ResponseEntity.badRequest().body(errors); } eventValidator.validate(event, errors); if(errors.hasErrors()) { return ResponseEntity.badRequest().body(errors); } Event newEvent = eventRepository.save(modelMapper.map(event, Event.class)); Integer eventId = newEvent.getId(); newEvent.update(); WebMvcLinkBuilder selfLinkBuilder = linkTo(EventController.class).slash(eventId); URI createdUri = selfLinkBuilder.toUri(); List<Link> links = Arrays.asList( selfLinkBuilder.slash(eventId).withSelfRel(), selfLinkBuilder.withRel("query-events"), selfLinkBuilder.withRel("update-event") ); EntityModel eventResource = EntityModel.of(newEvent, links); eventResource.add(); eventResource.add(); eventResource.add(selfLinkBuilder.withRel("update-event")); return ResponseEntity.created(createdUri).body(eventResource); }

감사합니다. 저도 안되서 Spring hateoas docs를 보니깐 ResourceSupport, Resource 객체가 1.2.1 버전부터 각각 RepresentationModel, EntityModel로 변경되었더라구요. 다른 수강생분들도 본인 hateoas 버전 확인해보시고 1.2.1 이라면 kmh님이작성한 코드로 진행하시면 될 것 같습니다. https://docs.spring.io/spring-hateoas/docs/1.2.0/reference/html/#migrate-to-1.0.changes
