BaseServlet (1)

内容介绍

一、BaseServlet

1.我们希望在一个 Servlet 中可以有多个请求处理方法！

domain: User

dao: UserDao

sezvice: DserService

servlet: UserServlet

vo1d init (ServletConfig config)

void destory()

void sezvice (ServlecRequest, ServletResponse)

throvs IOException, ServletException{

在这里让它去调用其他方法!

要求:用户发出请求时，必须给出一个参数，来说明要调用哪一个方法

获取参数，通过参数名称来确定要调用的方法

publ1c void addUser() (

btsp:/1coahost:8080/xx/AServlet7meaddUser

package en.itcast web.servlet;

import java.io. IOException;

在这里给出多个请求处理方法

请求处理方法:除了名称以外，都与 secvice 相同!

@author cxf

publio lass AServlet extends HttpServlet {

publio void doGet (HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException{

doPost (request, response);

public void doPost (HttpServletRequest req, HttpServletResponse resp)

throws ServletException, IOException {

11 TODO Auto-generated method stub

super.doPost(req, resp);

public void addUser (HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

system. out.println("addUser()...");

public void editUse (HttpServletRequest req,HttpServletResponse reap)

throws ServletException, IOException {

system. out.println("editUser()...");

public void deleteUse (HttpSezvletRequest req, HttpServletResponse resp)

throws ServletException, IOException {

System. out.println("deleteUser()...");
