Spring RequsetMapping의 부가적인 기능 컨트롤러 메서드의 HTTP 전송방식 한정

파일 위치 

[JSP/Spring] - Spring Web
이전 게시물

Command 클래스가 자바빈과 같다


방식과 요청을 따로 지정하기 위해 RequestMapping을 클래스에도 지정 

NewArticleController

Form이 있는경우에 코딩을 이러한 방식으로 한다


@ModelAttribute("command") newArticleCommand 라는 것은 알아서 객체 생성이 된걸 알아서 넣어준다

그래서 jsp 파일에서 호출이 잘된다 EL 표기법으로


설정이 자동으로 처리한 방식이라서 더욱 진보된 방식이라함
