package com.frame.base.TCP;import java.io.InputStream;import java.net.ServerSocket;import java.net.Socket;public class TCPSocketServer {public static void main(String[] args) throws Exception{/** * 启动服务端Soecket 注册外放信息交互的端口 */ServerSocket serverSocket = new ServerSocket(9999);//定义Socket对象监听9999端口接收的数据Socket socket = serverSocket.accept();System.out.println("IP:"+serverSocket.getInetAddress().getHostAddress()+"__连接上服务端开始接收数据...");//定义输入流和解析字节数据InputStream inputStream = socket.getInputStream();byte[] bytes = new byte[1024];int len = inputStream.read(bytes);System.out.println("读取的数据为:"+new String(bytes,0,len));//关闭客户端socket.close();//关闭服务端（可选）serverSocket.close();}}

2.客户端

package com.frame.base.TCP;import java.io.OutputStream;import java.net.Socket;public class TCPSocketClient {public static void main(String[] args) throws Exception {/** * 定义Socket 指定接入服务端的IP和外放端口 */Socket socket = new Socket("127.0.0.1", 9999);/** * 将请求数据封装到输出流中进行传递 */OutputStream out = socket.getOutputStream();out.write("TCPSocketClient说: 你好服务器".getBytes());socket.close();}}

3.运行结果
