Specified by:

getRequestHeaders in interface MultipartHttpServletRequest

getFileNames

public Iterator<String> getFileNames()

Description copied from interface: MultipartRequest

Return an Iterator of String objects containing the parameter names of the multipart files contained in this request. These are the field names of the form (like with normal parameters), not the original file names.

getFileNames in interface MultipartRequest

Returns:

the names of the files

getFile

public MultipartFile getFile(String name)

Description copied from interface: MultipartRequest

Return the contents plus description of an uploaded file in this request, or null if it does not exist.

name - a String specifying the parameter name of the multipart file

Returns:

the uploaded content in the form of a MultipartFile object

getFiles

public List<MultipartFile> getFiles(String name)

Description copied from interface: MultipartRequest

Return the contents plus description of uploaded files in this request, or an empty list if it does not exist.

Specified by:

getFiles in interface MultipartRequest

Parameters:

name - a String specifying the parameter name of the multipart file

Returns:

the uploaded content in the form of a MultipartFile list

getFileMap

public Map<String,MultipartFile> getFileMap()

Description copied from interface: MultipartRequest

Return a Map of the multipart files contained in this request.

Specified by:

getFileMap in interface MultipartRequest

Returns:

a map containing the parameter names as keys, and the MultipartFile objects as values

getMultiFileMap

public MultiValueMap<String,MultipartFile> getMultiFileMap()

Description copied from interface: MultipartRequest

Return a MultiValueMap of the multipart files contained in this request.

Specified by:

getMultiFileMap in interface MultipartRequest

Returns:

a map containing the parameter names as keys, and a list of MultipartFile objects as values

isResolved

public boolean isResolved()

Determine whether the underlying multipart request has been resolved.

Returns:

true when eagerly initialized or lazily triggered, false in case of a lazy-resolution request that got aborted before any parameters or multipart files have been accessed
