简易web服务器（java版）

//直接使用 ServerSocket 监听服务器端口，就能实现web服务器
package ThreadPoolTest;

import java.io.InputStream;
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.UnknownHostException;
import java.util.Date;
import java.util.concurrent.*;

public class Main {
    public static void main(String[] args)  throws UnknownHostException {
        HttpServer();
    }


    static  void  HttpServer(){

        ServerSocket serverSocket =null;
        try{
            serverSocket=new ServerSocket(91);
            InputStream inputStream;
            OutputStream outputStream;
            while (true){
                Socket socket=serverSocket.accept();
                inputStream=socket.getInputStream();
                outputStream=socket.getOutputStream();
                String msg="HTTP/1.1 200 OK 
";
                msg+="Content-Type:text/html
" ;
                msg+="Content-length:100
" ;
                msg+="
";
                msg+="<h1>cccccccccccccccccccccccccccccccc</h1>";

                outputStream.write(msg.getBytes());
                socket.close();
            }

        }
        catch (Exception ex){

        }

    }
}

效果如图
