1. 패키지 구조 생성
1) controller
2) action
3) model
4) dao(repository)
5) dto
6) db
7) util
2. 정적 폴더 구조 생성 WebContent 구조 생성
1) static
- css
- js
- image
2) member
3) post
3. 팩토리 세팅
1) com.cos.apple.action.Action.java
package com.cos.apple.db.action;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public interface Action {
void execute(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException;
}
2) com.cos.apple.action.post.PostListAction.java
package com.cos.apple.db.action.post;
import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.cos.apple.db.action.Action;
public class PostListAction implements Action{
@Override
public void execute(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
RequestDispatcher dis = request.getRequestDispatcher("index.jsp");
dis.forward(request, response);
}
}
3) PostController.java
- 주소 매핑(post)
package com.cos.apple.db.controller;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.cos.apple.db.action.Action;
import com.cos.apple.db.action.post.PostListAction;
//http://localhost:8000/apple/post
@WebServlet("/post")
public class PostController extends HttpServlet {
private static final long serialVersionUID = 1L;
public PostController() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doProcess(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doProcess(request, response);
}
protected void doProcess(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// 1. request utf-8 세팅 = web.xml 필터 등록함.
// 2. response utf-8 세팅
response.setCharacterEncoding("utf-8"); // 내가 상대한테 응답 시 바디에 담긴 거 인코딩.
response.setContentType("text/html; charset=utf-8"); // text/html은 default타입이에요.
String cmd = request.getParameter("cmd");
Action action = router(cmd);
action.execute(request, response);
}
private Action router(String cmd) {
if (cmd.equals("list")) {
return new PostListAction();
}
return null;
}
}
4. 동작 테스트
index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>게시글 목록 페이지</title>
</head>
<body>
<h1>게시글 목록 페이지</h1>
<hr />
</body>
</html>
