ftp.changeWorkingDirectory(path);

if (!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect();
return success;
}
ftp.changeWorkingDirectory(remotePath);//转移到FTP服务器目录
FTPFile[] fs = ftp.listFiles();
for(FTPFile ff:fs){
if(ff.getName().equals(fileName)){
File localFile = new File(localPath+"/"+ff.getName());
OutputStream is = new FileOutputStream(localFile);
ftp.retrieveFile(ff.getName(), is);
is.close();
}
}
ftp.logout();
success = true;
} catch (IOException e) {
e.printStackTrace();
} finally {
if (ftp.isConnected()) {
try {
ftp.disconnect();
} catch (IOException ioe) {
}
}
}
return success;
}
}
想知道一下这个里面的FTPClient这个类和FTPReply,FTPFile怎么报错,这3个是需要自己写的类吗?
