For some technical contraints I have to send and receive multipartfile data (small files size not a problem) with post rest encapsulated in base64 string.

I must verify file type (pdf) and file name after have decoded base64 string to multipartfile

I’m able to do this partial due to getBytes of multipartfile : only content is provided not full multipartfile objet.

I can’t create a custom object I must deal with string and multipartfile (base64)

Could you help me two find the solution ?

I only have 24 hours…

Thanks and sorry for my english
