Servlet實現自動刷新功能

使用Servlet實現自動刷新功能，每一秒鍾在瀏覽器輸出一個隨機數字。

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;

/**

@WebServlet("/ResponseDemo9")
public class ResponseDemo9 extends HttpServlet {
    private static final long serialVersionUID = 1L;
       
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        //設置一下自動刷新 功能
        response.setIntHeader("refresh", 1);  //這個是設置1秒自動刷新


        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);
    }
