本文介绍了一个简单的TCP文件上传应用，包含服务端与客户端代码。客户端从本地读取文本文件并将其发送到服务端，服务端将接收到的数据写入新文件，并反馈上传成功消息。

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();
	}

}
