WebServer服务器原理（例子）

import java.io.*;
import java.net.*;

public class WebServer{
    public static void main(String[] args) throws Exception{
        ServerSocket ss=new ServerSocket(6666);
        Socket s=ss.accept();

        OutputStream os=s.getOutputStream();
        BufferedReader br=new BufferedReader(new FileReader("D:\\index.html"));
        String buf="";
        while((buf=br.readLine())!=null){
            os.write(buf.getBytes());
        }
        //关闭流
        br.close();
        os.close();
        s.close();
    }
}
