FrontController 소스 / web.xml

<FrontController>

String contextPath = request.getContextPath(); → /Model, ContextPath : 실행되는 기본 폴더 위치

String url = request.getRequestURI(); → url 주소

String command = url.substring(contextPath.length()); → substring 문자열 자를때 (/Model 을 자르고 url만 입력하겠다)

if(command.equals("/Controller/~Servlet.do")){      → equals : 지금 들어오는, 현재 실행하는 경로    

ListServlet ls = new ListServlet();

ls.doGet(request, response);

this.view = "/model2/member/List.jsp";    → 그 다음 넘어갈 경로

this.isRedirect = false;            → forward 사용

//this.isRedirect = true;     → sendRedirect 사용하는경우

//this.isRedirect = false;    → forward(no isdirect)를 사용하는 경우 = false

} else if (command.equals("/Controller/WriteServlet.do")) {

WriteServlet ws = new WriteServlet();

ws.doPost(request, response);     → 객체에서 받다가 doGet으로 보내라

//실행구문 입력

this.view = "/model2/member/Write.jsp";

this.isRedirect = false;

}
