TCP实现 文本文件上传

上一篇博客介绍了TCP通信的实现方法，现在再做一个通过TCP实现文本文件上传的实例。

照旧先是客户端。

System.out.println("上传客户端。。。。。。");File file = new File("d:\\client.txt");System.out.println(file.exists());Socket s = new Socket("10.152.79.174", 10000);BufferedReader bufr = new BufferedReader(new FileReader(file));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 str = bufIn.readLine();System.out.println(str);bufr.close();s.close();

然后是服务端

System.out.println("上传服务端。。。。。。。。。");ServerSocket ss = new ServerSocket(10000);Socket s = ss.accept();System.out.println(s.getInetAddress().getHostAddress()+".....connected");BufferedReader bufIn = new BufferedReader(new InputStreamReader(s.getInputStream()));BufferedWriter bufw = new BufferedWriter(new FileWriter("D:\\server.txt"));String line = null;while((line=bufIn.readLine())!=null){bufw.write(line);bufw.newLine();bufw.flush();}PrintWriter out = new PrintWriter(s.getOutputStream(),true);out.println("上传成功");bufw.close();s.close();ss.close();

在运行时要注意在d盘下要有client.txt和server.txt文件，并且客户端文件要有内容。在运行时先运行服务端再运行客户端。
