smbj：如何仅获得子目录？

Question

I use https://github.com/hierynomus/smbj for samba access. I want get only the subfolders of my target directory. Whith following code I get "..", "." and all the files - is there an elegant way to get subdirectories only?

SmbConfig config = SmbConfig.builder().withMultiProtocolNegotiate(true).build();
    smbClient = new SMBClient(config);
    Connection connection = smbClient.connect(smbServerName);
    AuthenticationContext ac = new AuthenticationContext(smbUser, smbPassword.toCharArray(), smbDomain);
    Session session = connection.authenticate(ac);
    share =  (DiskShare) session.connectShare(smbShareName);    
    List<FileIdBothDirectoryInformation> subs = share.list("mydirWhichSubDirsIwant");

You need to filter out the results from the returned list. If you only want the subdirectories you can get them as follows:

List<String> subDirectories = new ArrayList<>();
for (FileIdBothDirectoryInformation sub: subs) {
    String filename = sub.getFileName();
    if (".".equals(filename) || "..".equals(filename)) {
        continue;
    }
    if (EnumWithValue.EnumUtils.isSet(sub.getFileAttributes(), FileAttributes.FILE_ATTRIBUTE_DIRECTORY)) {
        subDirectories.add(filename);
    }
}
