package com.avb.web;

import javax.servlet.*;
import javax.servlet.annotation.WebServlet;
import java.io.IOException;

@WebServlet("/demo01")//配置访问地址
public class Servletdemo01 implements Servlet {

    @Override
    public void service(ServletRequest servletRequest, ServletResponse servletResponse) throws ServletException, IOException {
        System.out.println("servlet hello world");
    }

    @Override
    public String getServletInfo() {
        return null;
    }

    @Override

    }
    @Override
    public void init(ServletConfig servletConfig) throws ServletException {

    }

    @Override
    public ServletConfig getServletConfig() {
