안녕하세요. hoon님, 공식 서포터즈 코즈위버 입니다.

클라이언트가 특정 url로 접속하면 스프링 프레임워크는 이 경로가 앱을 실행할 때 등록한 뷰 매핑에 있는지 검사하게 됩니다. 여기서 마땅한 매핑 결과를 찾지 못하거나 (404오류) 혹은 URL은 찾았지만 요구하는 HTTP메서드가 일치하지 않는경우(405오류)에 오류가 발생합니다.

감사합니다.

MvcMemberFormServlet 를 비워뒀더니 그런거였네요
근데 왜 비워두면 오류가 나면서 저런페이지가 뜨는건가요?? 
ServletApplication 가 시작의 기준아닌가요??
