Method Detail

getName

public String getName()

Description copied from interface: MultipartFile

Return the name of the parameter in the multipart form.

Specified by:

getName in interface MultipartFile

Returns:

the name of the parameter (never null or empty)

getOriginalFilename

@NonNull
public String getOriginalFilename()

Description copied from interface: MultipartFile

Return the original filename in the client's filesystem.

This may contain path information depending on the browser used, but it typically will not with any other than Opera.

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.

Specified by:

getOriginalFilename in interface MultipartFile

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

See Also:

FileItem.getName(), CommonsMultipartFile.setPreserveFilename(boolean), RFC 7578, Section 4.2, Unrestricted File Upload

getContentType

@Nullable
public String getContentType()

Description copied from interface: MultipartFile

Return the content type of the file.

Specified by:

getContentType in interface MultipartFile

Returns:

the content type, or null if not defined (or no file has been chosen in the multipart form)

isEmpty

public boolean isEmpty()

Description copied from interface: MultipartFile

Return whether the uploaded file is empty, that is, either no file has been chosen in the multipart form or the chosen file has no content.

Specified by:

isEmpty in interface MultipartFile

getSize

public long getSize()

Description copied from interface: MultipartFile

Return the size of the file in bytes.

Specified by:

getSize in interface MultipartFile

Returns:

the size of the file, or 0 if empty

getBytes

public byte[] getBytes()
                throws IOException

Description copied from interface: MultipartFile

Return the contents of the file as an array of bytes.

Specified by:

getBytes in interface MultipartFile

Returns:

the contents of the file as bytes, or an empty byte array if empty

Throws:

IOException - in case of access errors (if the temporary store fails)

getInputStream

public InputStream getInputStream()
                           throws IOException

Description copied from interface: MultipartFile

Return an InputStream to read the contents of the file from.

The user is responsible for closing the returned stream.

Specified by:

getInputStream in interface InputStreamSource

Specified by:

getInputStream in interface MultipartFile

Returns:

the contents of the file as stream, or an empty stream if empty

Throws:

IOException - in case of access errors (if the temporary store fails)

Resource.isReadable()

transferTo

public void transferTo(File dest)
                throws IOException,
                       IllegalStateException

Description copied from interface: MultipartFile

Transfer the received file to the given destination file.

This may either move the file in the filesystem, copy the file in the filesystem, or save memory-held contents to the destination file. If the destination file already exists, it will be deleted first.

If the target file has been moved in the filesystem, this operation cannot be invoked again afterwards. Therefore, call this method just once in order to work with any storage mechanism.

NOTE: Depending on the underlying provider, temporary storage may be container-dependent, including the base directory for relative destinations specified here (e.g. with Servlet 3.0 multipart handling). For absolute destinations, the target file may get renamed/moved from its temporary location or newly copied, even if a temporary copy already exists.

Specified by:

transferTo in interface MultipartFile

Parameters:

dest - the destination file (typically absolute)

Throws:

IOException - in case of reading or writing errors

IllegalStateException - if the file has already been moved in the filesystem and is not available anymore for another transfer
