ok， I got the progress of file downloading.
1) I create two new class MyFileSystemView and MyFtpFile
public class MyFtpFile extends NativeFtpFile {
private CountingInputStream InputCount = null;
private CountingOutputStream OutputCount = null;
protected MyFtpFile (final String fileName, final File file, final User
user) {
super(fileName,file,user);
}
@Override
public OutputStream createOutputStream(long offset) throws IOException {
OutputStream outputs = super.createOutputStream(offset);
OutputCount = new CountingOutputStream(outputs);
return outputs;
}
@Override
public InputStream createInputStream(long offset) throws IOException {
InputStream ins = super.createInputStream(offset);
InputCount = new CountingInputStream(ins);
return new SwappedDataInputStream(InputCount);
}
public CountingInputStream getInputCount() {
return InputCount;
}
public CountingOutputStream getOutputCount() {
return OutputCount;
}
}
public class MyFileSystemView implements FileSystemView {
@Override
public FtpFile getFile(String file) {
// get actual file object
String physicalName = SeedFtpFile.getPhysicalName(rootDir,
currDir, file, caseInsensitive);
File fileObj = new File(physicalName);
// strip the root directory and return
String userFileName = physicalName.substring(rootDir.length() - 1);
MyFtpFile ftpfile = new MyFtpFile (userFileName, fileObj, user);
if (userFtpManager != null) { // the
userFtpManager is my own object for to mamanger the ftpfile object
userFtpManager.setFtpFile(user, ftpfile);//to save the new
ftpfile
}
return ftpfile;
}
.
.
}
2) inject it into the ftpserver
m_FtpServerFactory = new FtpServerFactory();
m_FtpServerFactory.setFileSystem(new MyFileSystemFactory());
3) to get progress for file downloading
userFtpManager.getDownloadPercent(User user) {
if (CurrFtpFile != null) {
CountingInputStream count = CurrFtpFile.getInputCount();
if (count != null) {
double totalSize = CurrFtpFile.getSize();
int percent = (int) (((double)(count.getByteCount()) /
totalSize) * 100L);
System.out.println(String.format(User:%s File:%s read
%d-%d percent:%d , TerminalCode, CurrFtpFile.getName(),
count.getByteCount(), count.getCount(),percent));
return percent;
}
}
return 0;
}

thank sam, I try to do it now!

You need to have your own FileSystemView and FtpFile. In the FtpFile,
there are two methods createInputStream and createOutputStream. Pass your
own child class for inputstream and outputstream, override read and write
respectively and accordingly show your progress.

Subject: Re: how can get file downloading progress?
thank you! I have been defined a ftplet class for myself already, but the
onDownloadEnd and onDownloadStart function can not get downloading
progress. My mean is to get a percent of the file downloading from
server. how do to it?

Look at the ftplet interface.
https://cwiki.apache.org/FTPSERVER/ftplet.html
Specifically the onDownloadEnd() method.
