一、请求转发
- OneServlet
package com.lpx.controller;import javax.servlet.*;
import javax.servlet.http.*;
import java.io.IOException;public class OneServlet extends HttpServlet {@Overrideprotected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {System.out.println("OneServlet 负责洗菜");RequestDispatcher report = request.getRequestDispatcher("one.do");//请求转发时不能从网站根目录名称开始写report.forward(request,response);}@Overrideprotected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {}
}
- TwoServlet
package com.lpx.controller;import javax.servlet.*;
import javax.servlet.http.*;
import java.io.IOException;public class TwoServlet extends HttpServlet {@Overrideprotected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {System.out.println("TwoServlet负责炒菜");}@Overrideprotected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {}
}
