(1)创建servlet BrowserServer
(2)调用HttpServletRequest对象的getServerName()方法获取服务器名称
(3)调用HttpServletRequest对象的getServerPort()方法获取服务器端口
(4)首先调用getServletContext()方法获取ServletContext对象,然后调用ServletContext对象的getServerInfo()方法获取服务器环境信息名称、版本信息
(5)利用HttpServletResponse对象的PrintWriter将信息显示到页面

package example.servlet;

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

import javax.servlet.ServletContext;
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 BrowserServer
 */
@WebServlet("/BrowserServer")
public class BrowserServer extends HttpServlet {
  private static final long serialVersionUID = 1L;
    
  
  protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.setContentType("text/html;charset=utf-8");
    PrintWriter out=response.getWriter();
    ServletContext context=getServletContext();
    
    out.println("");
    out.println("");
    out.println("服务器信息");
    out.println("");
    out.println("");
    out.println("

服务器名称:"+request.getServerName()+"

"); out.println("

服务器端口:"+request.getServerPort()+"

"); out.println("

"+context.getServerInfo()+"

"); out.println(""); out.println(""); out.close(); } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { processRequest(request,response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { processRequest(request,response); } }
