java ftp客户端源代码

自己写了一个简单的ftp客户端，这个客户端主要使用的是FtpClient这个类，这个类处于jdk的lib/rt.jar包中。现在实现了文件上传，文件夹上传。其余的功能有待补充。

代码如下：

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import sun.net.TelnetOutputStream;
import sun.net.ftp.FtpClient;

public class FtpUpload {

 FtpClient ftpClient = new FtpClient();

 String sServer = "";

 String sUser = "";

 String sPassword = "";

 /**
  * @return Returns the sPassword.
  */
 public String getSPassword() {
  return sPassword;
 }

 /**
  * @param password
  *            The sPassword to set.
  */
 public void setSPassword(String password) {
  sPassword = password;
 }

 /**
  * @return Returns the sServer.
  */
 public String getSServer() {
  return sServer;
 }

 /**
  * @param server
  *            The sServer to set.
  */
 public void setSServer(String server) {
  sServer = server;
 }

 /**
  * @return Returns the sUser.
  */
 public String getSUser() {
  return sUser;
 }

 /**
  * @param user
  *            The sUser to set.
  */
 public void setSUser(String user) {
  sUser = user;
 }

 private void setLoginInfo(String strServerIp, String strUser, String strPasswd) {
  sServer = strServerIp;
  sUser = strUser;
  sPassword = strPasswd;
 }

 private void connect() throws IOException {
  ftpClient.openServer(sServer);
  ftpClient.login(sUser, sPassword);
  ftpClient.binary();  
 }

 private void uploadFolder(String strFoldName) throws IOException {
  File f = new File(strFoldName);
  if (!f.exists()) {
   return;
  }
  File subFile[] = f.listFiles();
  for (int i = 0; i < subFile.length; i++) {
   uploadFile(subFile[i], subFile[i].getName());
  }
 }

 private void uploadFile(String strSrcFileName, String strObjFileName) throws IOException {
  File file_in = new File(strSrcFileName);
  uploadFile(file_in, strObjFileName);
 }

 private void uploadFile(File fScrFile, String strObjFileName) throws IOException {
  TelnetOutputStream os = ftpClient.put(strObjFileName);
  FileInputStream is = new FileInputStream(fScrFile);
  byte[] bytes = new byte[1024];
  int c;
  while ((c = is.read(bytes)) != -1) {
   os.write(bytes, 0, c);
  }
  is.close();
  os.close();
  log(" 「" + strObjFileName + "」 File has been uploaded。/r/n");
 }

 private void closeConnect() throws IOException {
  ftpClient.closeServer();
 }

 private void log(Object obj) {
  System.out.println(obj);
 }

 public static void main(String[] args) throws Exception {

  FtpUpload ftp = new FtpUpload();
  ftp.setLoginInfo("203.186.92.88", "anonymous", "anonymous");
  ftp.connect();
  ftp.uploadFolder("C:/ftp/");
  ftp.uploadFile("C:/ftp/log.txt","ftplog.txt");
  ftp.closeConnect();
 }

}
