Method Detail

filename

String filename()

Return the original filename in the client's filesystem.

Note: Please keep in mind this filename is supplied by the client and should not be used blindly. In addition to not using the directory portion, the file name could also contain characters such as ".." and others that can be used maliciously. It is recommended to not use this filename directly. Preferably generate a unique one and save this one somewhere for reference, if necessary.

Returns:

the original filename, or the empty String if no file has been chosen in the multipart form, or null if not defined or not available
