1、/*** 登陆FTP服务器* @param host FTPServer IP地址* @param port FTPServer 端口* @param username FTPServer 登陆用户名* @param password FTPServer 登陆密码* @return 是否登录成功* @throws IOException*/public boolean login(String host,int port,String username,String password) throws IOException{this.ftp.connect(host,port);if(FTPReply.isPositiveCompletion(this.ftp.getReplyCode())){if(this.ftp.login(username, password)){this.ftp.setControlEncoding("GBK");return true;}}if(this.ftp.isConnected()){this.ftp.disconnect();}return false;}

2、/*** 关闭数据链接* @throws IOException*/public void disConnection() throws IOException{if(this.ftp.isConnected()){this.ftp.disconnect();}}

3、/*** 递归遍历出目录下面所有文件* @param pathName 需要遍历的目录,必须以&孥恶膈茯quot;/"开始和结束* @throws IOException*/public String List(String pathName) throws IOException{StringBuffer filename=new StringBuffer();if(pathName.startsWith("/")&&pathName.endsWith("/")){String directory = pathName;//更换目录到当前目录this.ftp.changeWorkingDirectory(directory);ftp.enterLocalPassiveMode();FTPFile[] files = this.ftp.listFiles();  if(files!=null){    for (int i = 0; i < files.length; i++) {      if(files[i].isFile()){        String n=new String(files[i].getName().getBytes("gbk"),"utf-8");        if(i==files.length-1){        filename.append(n+","+showPath);       }else{          filename.append(n+",");         }      }    }   }  }    return filename.toString();}

4、//获取指定文件夹内的文件名称public static String getFilenames猾诮沓靥(){  String names="";  FTPListA造婷用痃llFiles f = new FTPListAllFiles();  try {     if(f.login(FAR_SERVER_URL, SERVER_PORT, SERVER_USER, SERVER_PWD)){      names= f.List(path);     }    } catch (IOException e) {        // TODO Auto-generated catch block        e.printStackTrace();    } finally{        try {            f.disConnection();          } catch (IOException e) {              // TODO Auto-generated catch block              e.printStackTrace();          }        }      return names;  }

5、//测试/* public static void main(String[] args) throws IOException {  System.out.println(getFilenames());} */}
