服务端：

package cn.net.tcp;import java.io.BufferedReader;import java.io.FileReader;import java.io.FileWriter;import java.io.IOException;import java.io.InputStreamReader;import java.io.PrintWriter;import java.net.ServerSocket;import java.net.Socket;public class uploadServer {/** * @param args * @throws IOException */public static void main(String[] args) throws IOException {System.out.println("服务端启动...");ServerSocket ss = new ServerSocket(10005);Socket s = ss.accept();String ip = s.getInetAddress().getHostAddress();System.out.println(ip + "...connected");BufferedReader bufr = new BufferedReader(new InputStreamReader(s.getInputStream()));PrintWriter pw = new PrintWriter(new FileWriter("server.txt"), true);String line = null;while ((line = bufr.readLine()) != null) {pw.println(line);}PrintWriter out = new PrintWriter(s.getOutputStream(), true);out.println("上传成功");pw.close();s.close();ss.close();}}

客户端：

package cn.net.tcp;import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;import java.io.InputStreamReader;import java.io.PrintWriter;import java.net.Socket;import java.net.UnknownHostException;public class uploadtxtClient {/** * @param args * @throws IOException * @throws UnknownHostException */public static void main(String[] args) throws UnknownHostException,IOException {/* * 上传文本的客户端，读取本地文本数据，发送给服务端，服务端接收完毕后，回馈“上传成功”字样。 */System.out.println("客户端启动了...");Socket s = new Socket("127.0.0.1", 10005);BufferedReader bufr = new BufferedReader(new FileReader("client.txt"));PrintWriter out = new PrintWriter(s.getOutputStream(), true);String line = null;while ((line = bufr.readLine()) != null) {out.println(line);}s.shutdownOutput();BufferedReader bufIn = new BufferedReader(new InputStreamReader(s.getInputStream()));String linIn = bufIn.readLine();System.out.println(linIn);bufIn.close();s.close();}}
