I've had success developing similar endpoints that accept multiple files along with their metadata in JSON format.

curl -i -X POST -H "Content-Type: multipart/mixed" -F "blob=@/Users/username/Documents/bio.jpg" -F "metadata={\"edipi\":123456789,\"firstName\":\"John\",\"lastName\":\"Smith\",\"email\":\"john.smith@gmail.com\"};type=application/json" http://localhost:8080/api/v1/user/

Notice the addition of ;type=application/json at the end of the metadata request part. When uploading multiple files of different types, you can define the mime type at the end of the -F value.

I have confirmed that this works for Spring MVC 4.3.7 using @RequestPart. The key in that instance is to not provide the consumes value on the @RequestMapping annotation.
