Socket搭建客户端和服务端

import java.net.ServerSocket;
import java.net.Socket;
/**
 * server服务路径下

	public static void main(String[] args) throws Exception {
		ServerSocket ss = new ServerSocket(6789);
		while(true){
			Socket s = ss.accept();
			InputStream is = s.getInputStream();
			BufferedReader br = new BufferedReader(new InputStreamReader(is));
			String res = br.readLine();
			System.out.println("服务端输出:"+res);
			
			br.close();
			is.close();
			s.close();
		}

	}
