Java判断Ftp服务器目录是否存在,若不存在创建目录 .

?解决方法1：

?

package com.soft4j.log4j;import java.io.IOException;import sun.net.ftp.FtpClient;public class FtpTest{ static String middle_ftpServer = "10.103.2.250"; static String middle_user = "ora9iftp"; static String middle_password = "ftp"; static String middle_dir = "/image/NWKPHOTO/Middle/2009/3"; public static void main(String[] args) {  FtpClient ftpClient = new FtpClient();  try  {   ftpClient.openServer(middle_ftpServer);   ftpClient.login(middle_user, middle_password);   FtpTest ft =  new FtpTest();   ft.isDirExist(ftpClient, middle_dir);  } catch (IOException e)  {   e.printStackTrace();  } } /** 判断Ftp目录是否存在,如果不存在则创建目录 */ public void isDirExist(FtpClient ftpClient, String dir) {  try  {   ftpClient.cd(dir);  //想不到什么好办法来判断目录是否存在，只能用异常了(比较笨).请知道的告诉我一声`  } catch (IOException e1)  {   ftpClient.sendServer("MKD " + dir + "/r/n");   try   {    ftpClient.readServerResponse();   } catch (IOException e)   {    e.printStackTrace();   }  } }}

解决方法2：

public void md(String path) throws Exception {fc.sendServer("XMKD " + path+"\r\n");}
