构造器详细资料

• CommonsMultipartFile

  public CommonsMultipartFile​(org.apache.commons.fileupload.FileItem fileItem)

  Create an instance wrapping the given FileItem.

  参数:

  fileItem - the FileItem to wrap

方法详细资料

• getFileItem

  public final org.apache.commons.fileupload.FileItem getFileItem()

  Return the underlying org.apache.commons.fileupload.FileItem instance. There is hardly any need to access this.

• setPreserveFilename

  public void setPreserveFilename​(boolean preserveFilename)

  Set whether to preserve the filename as sent by the client, not stripping off path information in getOriginalFilename().

  Default is "false", stripping off path information that may prefix the actual filename e.g. from Opera. Switch this to "true" for preserving the client-specified filename as-is, including potential path separators.

  从以下版本开始:

  4.3.5

  getOriginalFilename(), CommonsFileUploadSupport.setPreserveFilename(boolean)

• getName

  public String getName()

  从接口复制的说明: MultipartFile
  Return the name of the parameter in the multipart form.

  指定者:

  getName 在接口中 MultipartFile

  返回:

  the name of the parameter (never null or empty)

• getOriginalFilename

  public String getOriginalFilename()

  从接口复制的说明: 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.

  指定者:

  getOriginalFilename 在接口中 MultipartFile

  返回:

  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

  FileItem.getName(), setPreserveFilename(boolean)

• getContentType

  public String getContentType()

  从接口复制的说明: MultipartFile
  Return the content type of the file.

  指定者:

  getContentType 在接口中 MultipartFile

  返回:

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

• isEmpty

  public boolean isEmpty()

  从接口复制的说明: 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.

  指定者:

  isEmpty 在接口中 MultipartFile

• getSize

  public long getSize()

  从接口复制的说明: MultipartFile
  Return the size of the file in bytes.

  指定者:

  getSize 在接口中 MultipartFile

  返回:

  the size of the file, or 0 if empty

• getBytes

  public byte[] getBytes()

  从接口复制的说明: MultipartFile
  Return the contents of the file as an array of bytes.

  指定者:

  getBytes 在接口中 MultipartFile

  返回:

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

• getInputStream

  public InputStream getInputStream()
                             throws IOException

  从接口复制的说明: MultipartFile
  Return an InputStream to read the contents of the file from.

  The user is responsible for closing the returned stream.

  指定者:

  getInputStream 在接口中 InputStreamSource

  指定者:

  getInputStream 在接口中 MultipartFile

  返回:

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

  抛出:

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

• transferTo

  public void transferTo​(File dest)
                  throws IOException,
                         IllegalStateException

  从接口复制的说明: 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.

  指定者:

  transferTo 在接口中 MultipartFile

  参数:

  dest - the destination file (typically absolute)

  抛出:

  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

• isAvailable

  protected boolean isAvailable()

  Determine whether the multipart content is still available. If a temporary file has been moved, the content is no longer available.

• getStorageDescription

  public String getStorageDescription()

  Return a description for the storage location of the multipart content. Tries to be as specific as possible: mentions the file location in case of a temporary file.
