'회원관리 웹 어플리케이션 2 ' 포스팅 에서 이어지는 포스팅으로,
장바구니 기능을 하는 웹 어플리케이션 프로그램이다.
[ 구성이 달라지는 점 ]
1. layout.jsp를 한 가지로 합침
1) login 시 - [ ]님 로그인 / 로그아웃 링크
2) login 아닐 시 - 로그인 폼
2. home의 main 화면을 켜자마자 item 목록 리스트 보여주기
- home.jsp 수정 + HomeController에 item 목록 리스트 보여주는 기능 추가하기
[ 프로그램 진행 원리 및 개요 ]
웹 페이지에서 동적으로 이동되는 부분(메인 화면)만 새로 업데이트하여 보여주기 위하여,
전체적인 layout을 잡아두고, 메인 화면에 기능에 따른 새로운 view(jsp)를 할당하여 동작하도록 한다.
기능 1. layout 화면을 로그인 + 비로그인으로 합쳐서 제공 (session을 통해 다른 화면 제공)
기능 2 : 로그인 + 로그아웃
기능 3 : 로그인 상태에서, 상품 등록 기능

handleRequest method 작동 방식
1. 에러(예외) 발생 시, 콘솔에 메세지 발생 경로 출력 후, error.jsp로 redirect 방식으로 view로 이동한다.
2. 클라이언트가 전송한 command 정보를 받는다.
3. HandlerMapping 을 이용해 개별 컨트롤러 객체를 컨트롤러 인터페이스 타입으로 반환받는다.
4. 개별 컨트롤러를 실행한다.
5. 실행 후 반환된 String url 정보를 이용해,
forward 방식 or redirect 방식으로 view로 이동해 응답하게 한다.
