String FTP_USERNAME = "kak";//电脑用户名
String FTP_PASSWORD = "123456";//电脑开机密码

ftpClient = new FtpClient();

String remotePath="/niuxi";
String fname="催收.xls";
Ftp ftpInterface=new Ftp();

// 登录ftp，获取事件

FTPClient ftp1 = ftpInterface.ftp(FTP_IP, FTP_USERNAME, FTP_PASSWORD);//这里是ip，用户名，密码
 InputStream is;

//时间正则表达式
 
try {
boolean aaa=ftp1.changeWorkingDirectory(new String(remotePath.getBytes(),"ISO-8859-1"));

//这里最大的坑就是这个remotePath地址了要访问具体哪个电脑要先开放那台电脑的ftp具体开放步骤百度下当你设置好具体电脑的ftp地址后这里的remotePath是你设置的ftp地址（E：/ftp

）中的文件夹名称我在ftp文件夹中建立了个niuxi文件夹
is=ftp1.retrieveFileStream(new String(fname.getBytes(),"ISO-8859-1"));
