차정보 조회 form.jsp에서 FrontControllerServlet으로 차번호(CarNo)와 hidden command(FindCar)을 보낸다.

 

FrontControllerServlet.java

package org.kosta.webstudy17.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 org.kosta.webstudy17.model.MockDAO;

@WebServlet("/FrontControllerServlet")
public class FrontControllerServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
    public FrontControllerServlet() {
        super();
    }

	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		handleRequest(request,response);
		
	
	}

	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		request.setCharacterEncoding("utf-8");
		handleRequest(request,response);

	}

 

FrontControllerServlet의 나머지 코드는 뒤의 예제들에서 찾아보자
