java获取服务器基本信息的简单操作

今天就来分享一个java获取服务器基本信息的简单操作


实现步骤：


　　（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("");
        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);
    }


}
