1.编写一个类去继承httpServlet类
2.根据业务需要重写doget或者dopost方法
3.到web.xml配置servlet程序访问地址

package com.atguigu.servlet;


import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class HelloServlet1 extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
super.doGet(req, resp);
}

@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
super.doPost(req, resp);
}
}

写好以后去配置访问地址‘
直接newservlet

interface servlet
实现接口↑
class cenericservlet
继承↑
class httpservlet
继承↑
自定义的servlet程序
