今天演示第一个web小程序
首先列举所需工具
1.tomcat9.0.13服务器软件
2.eclipse软件
首先使用eclipse切换到javaweb工作空间
点击这个按钮在里面找到javaEE就OK了
接下来创建一个动态javaweb项目
写一下如下代码
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;/** * Servlet implementation class helllo */@WebServlet("/helllo")public class helllo extends HttpServlet {private static final long serialVersionUID = 1L; ??????????/** ????* @see HttpServlet#HttpServlet() ????*/ ???public helllo() { ???????super(); ???????// TODO Auto-generated constructor stub ???}/** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) */protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {// TODO Auto-generated method stubresponse.getWriter().append("Hello World!!!").append(request.getContextPath());}/** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) */protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {// TODO Auto-generated method stubdoGet(request, response);}}然后就ojbk了
