真诚为您提供优质参考资料，若有不当之处，请指正。TCP协议上传图片客户端和服务端 TCP服务端1. import java.io.IOException;2. import .ServerSocket;3. import .Socket;4. import java.io.InputStream;5. import java.io.File;6. import java.io.FileOutputStream;7. import java.io.OutputStream;8. import java.io.FileNotFoundException;9. import java.io.IOException;10.11. public class UploadPicServer12. 13. public static void main(String args) throws FileNotFoundException,IOException 14. 15. /创建tcp的socket服务端。16. ServerSocket ss = new ServerSocket(10006);17.18. /获取客户端。19. Socket s = ss.accept();20.21. String ip = s.getInetAddress().getHostAddress();22. System.out.println(ip + .connected);23.24. /读取客户端发来的数据。25. InputStream in = s.getInputStream();26.27. /将读取到的数据存储到一个文件中。28. File dir = new File(c:pic);29. if(!dir.exists()30. dir.mkdirs();31. 32. File file = new File(dir,ip + .bmp);33. FileOutputStream fos = new FileOutputStream(file);34.35. byte buf = new byte1024;36. 37. int len = 0;38.39. while(len = in.read(buf) != -1)40. fos.write(buf,0,len);41. 42.43. /获取socket输出流，将上传成功字样发给客户端。44.
