[JSP-2편](mysql) web.xml mapping 설정

 

 

 

 

 

1. web-xml 에 들어가서 

 

 

 <servlet>
    <servlet-name>FrontController</servlet-name>
    <servlet-class>jspstudy.controller.FrontController</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>FrontController</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

 

 

2. Controller 에서 Frontcontrooler 똑같이 맞춰주세요 !! !

 

 

 

 

3. 가상경로 만들어주기 !!

@WebServlet("/FrontController")
public class FrontController extends HttpServlet {
    private static final long serialVersionUID = 1L;
          
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
            
        String uri = request.getRequestURI();
        System.out.println("uri =" +uri);
        String pj = request.getContextPath();
        System.out.println("pj =" +pj);
        String command = uri.substring(pj.length());  //프로젝트이름을 뺀 나머지 가상경로 추출    
        System.out.println("command =" +command);
        // ex)   /member/memberList.do
        
        String[] subpath = command.split("/");
        String location = subpath[1];        // member 문자열이 추출
        
        if (location.equals("member")) {
            MemberController mc = new MemberController();
            mc.doGet(request, response);
            
        }else if (location.equals("board")) {
            BoardController bc = new BoardController();
            bc.doGet(request, response);            
        }
        
        
        
        
    }
 
    
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
    }
 

 

 

4. 가상경로에 맞는 컨트롤러로 이동 !

 

 

 

 

5. 가상경로에 맞는 컨트롤러로 이동 !

 

 

 

 

6.  command 값과 같은 주소값을 매핑시켜서 맞으면 로직 실행 !

 

 

@WebServlet("/BoardController")
public class BoardController extends HttpServlet {
    private static final long serialVersionUID = 1L;
       
    
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        
        //가상경로로 온 request가 있으면  처리
        request.setCharacterEncoding("UTF-8");
        response.setContentType("text/html;charset=UTF-8");
        
        String uri = request.getRequestURI();
        String pj = request.getContextPath();
        String command = uri.substring(pj.length());
        
        int sizeLimit = 1024*1024*15;
        String uploadPath="E:\\openApi(B)\\dev\\jspstudy\\src\\main\\webapp\\";
        String saveFolder="images";
        String saveFullPath = uploadPath+saveFolder;
        
        
        if (command.equals("/board/boardWrite.do")) {
            System.out.println("글쓰기 화면에 들어왔음");
            
            RequestDispatcher rd = request.getRequestDispatcher("/board/boardWrite.jsp");
            rd.forward(request, response);
