1、服务器端代码如下

package com.njupt.webservice;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.net.ServerSocket;import java.net.Socket;public class Server {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 str = br.readLine();System.out.println("客户端说：" + str);br.close();is.close();s.close();}}}

2、客户端代码如下：

package com.njupt.webservice;import java.io.BufferedWriter;import java.io.IOException;import java.io.OutputStream;import java.io.OutputStreamWriter;import java.net.Socket;import java.net.UnknownHostException;public class Client {public static void main(String[] args) throws Exception {Socket s = new Socket("127.0.0.1",6789);OutputStream os = s.getOutputStream();BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(os));bw.write("我喜欢章泽天?");bw.close();os.close();s.close();}}
