我们可以从byteArrayResource获取文件名吗？

Question

It's about uploading xlsx file. Initially im getting xlsx file as javax.servlet.http.Part and trying to convert as ByteArrayResource Since i need to pass via RestTemplate .

new ByteArrayResource(IOUtils.toByteArray(input.getFile().getInputStream())

Here input.getFile() is javax.servlet.http.Part

As im converting here into ByteArrayResource and sending back to another Layer for business logic, can i get filename from ByteArrayResource ?

Anyhow we can get filename from Part , I want to know is that possible to get filename from ByteArrayResource or ByteArray ?

You'll probably need to use FileNameAwareByteArrayResource as outlined in this answer

and you'll be able to get filename from it then.
