Posted 2020-10-31

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

//扩展 HttpServlet实现Servlet程序
public class Demo13 extends HttpServlet {
    //如果浏览器是以get方式提交，则覆写doGet()方法
    public void doGet(
            HttpServletRequest request, 
            HttpServletResponse response)
        throws ServletException, IOException {

        PrintWriter pw = response.getWriter();
        pw.write("<ol>");
            pw.write("<li>JavaServlet</li>");
            pw.write("<li>JavaJsp</li>");
            pw.write("<li>JavaStruts</li>");
        pw.write("</ol>");

    }
}
