ByteArrayResource

open class ByteArrayResource : AbstractResource

Resource implementation for a given byte array.

Creates a ByteArrayInputStream for the given byte array.

Useful for loading content from any given byte array, without having to resort to a single-use InputStreamResource. Particularly useful for creating mail attachments from local content, where JavaMail needs to be able to read the stream multiple times.
