org.apache.commons.net.ftp.* 看這個目錄下是否有妳要的方法
第二種方法：
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();
}
}
/** 判斷Ftp目錄是否存在,如果不存在則創建目錄 */
public void isDirExist(FtpClient ftpClient, String dir)
{
try
{
ftpClient.cd(dir); //想不到什麽好辦法來判斷目錄是否存在，只能用異常了(比較笨).請知道的告訴我壹聲`
} catch (IOException e1)
{
ftpClient.sendServer("MKD " + dir + "\r\n");
try
{
ftpClient.readServerResponse();
} catch (IOException e)
{
e.printStackTrace();
}
}
}
}
