Servlet实现自动刷新功能

使用Servlet实现自动刷新功能，每一秒钟在浏览器输出一个随机数字。

package chensi.com;

import java.io.IOException;

import java.util.Random;

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 Servlet实现自动刷新 功能(每秒钟在页面 输出一个数字)

 */

@WebServlet("/ResponseDemo9")

public class ResponseDemo9 extends HttpServlet {

    private static final long serialVersionUID = 1L;

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        //设置一下自动刷新 功能

        response.setIntHeader("refresh", 1);  //这个是设置1秒自动刷新

        Random r = new Random();

        System.out.println(r.nextInt(10)+1);

        response.getWriter().write(r.nextInt(10)+1+"");

    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        // TODO Auto-generated method stub

        doGet(request, response);

    }

}
