구현 내용
@controller / @RequestMapping 애너테이션
@Controller—@Component메타 애너테이션 포함, 빈 자동 등록@RequestMapping— 클래스/메서드 레벨 모두 지원, HTTP Method 매핑 추가RequestMethodenum — GET, POST, PUT, DELETE 등HandlerKey & HandlerMethod
HandlerKey— URL + HTTP Method 조합 복합 키HandlerMethod— 리플렉션으로 컨트롤러 메서드 동적 실행HandlerMapping / HandlerAdapter 추상화
HandlerMapping인터페이스 — 요청에서 핸들러 탐색HandlerAdapter인터페이스 — 핸들러 실행 추상화SimpleUrlHandlerMapping— 기존 Controller 인터페이스 방식 유지AnnotationHandlerMapping— @controller 스캔 및 URL+Method 자동 매핑SimpleControllerHandlerAdapter— Controller 인터페이스 처리AnnotationHandlerAdapter— HandlerMethod 처리LectureController 마이그레이션
Controller인터페이스 구현 제거handleRequest()내부 GET/POST 수동 분기 제거@RequestMapping(methods = RequestMethod.GET/POST)선언변경 전후
[Before]
LectureController→Controller인터페이스 구현 필수handleRequest()안에서request.getMethod()로 직접 분기[After]
LectureController→ 인터페이스 구현 없이@Controller만 선언DispatcherServlet→HandlerMapping/Adapter기반으로 새 방식 추가 시 코드 변경 불필요체크리스트
