public class InputStreamResource extends AbstractResource
Resource implementation for a given InputStream.
 Should only be used if no other specific Resource implementation
 is applicable. In particular, prefer ByteArrayResource or any of the
 file-based Resource implementations where possible.
 
In contrast to other Resource implementations, this is a descriptor
 for an already opened resource - therefore returning true from
 isOpen(). Do not use an InputStreamResource if you need to
 keep the resource descriptor somewhere, or if you need to read from a stream
 multiple times.
