public byte[] getFileData()
                   throws java.io.FileNotFoundException,
                          java.io.IOException

Returns the data for this file as a byte array. Note that this may result in excessive memory usage for large uploads. The use of the getInputStream method is encouraged as an alternative.

定義:

インタフェース FormFile 内の getFileData

戻り値:

An array of bytes representing the data contained in this form file.

例外:

java.io.FileNotFoundException - If some sort of file representation cannot be found for the FormFile

getBaseFileName

protected java.lang.String getBaseFileName(java.lang.String filePath)

Returns the base file name from the supplied file path. On the surface, this would appear to be a trivial task. Apparently, however, some Linux JDKs do not implement File.getName() correctly for Windows paths, so we attempt to take care of that here.

パラメータ:

filePath - The full path to the file.

戻り値:

The base file name, from the end of the path.

toString

public java.lang.String toString()

Returns the (client-side) file name for this file.
