@RequestPart with mixed multipart request, Spring MVC 3.2

Question

I\'m developing a RESTful service based on Spring 3.2. I\'m facing a problem with a controller handling mixed multipart HTTP request, with a Second part with XMLor JSON form

Answer 1

Not sure if you had fixed your problem, but I also had a similar problem where my JSON object was not getting picked up by my controller when mixing @RequestPart and MultipartFile together.

The method signature for your call looks correct:

public ResponseEntity>> createUser(
        @RequestPart("file") MultipartFile file, @RequestPart(required=false) User user) {

// ... CODE ... 
}

However make sure your request looks something like this:

POST /createUser
Content-Type: multipart/mixed; boundary=B0EC8D07-EBF1-4EA7-966C-E492A9F2C36E

--B0EC8D07-EBF1-4EA7-966C-E492A9F2C36E
Content-Disposition: form-data; name="user";
Content-Type: application/xml; charset=UTF-8


--B0EC8D07-EBF1-4EA7-966C-E492A9F2C36E
Content-Disposition: form-data; name="file"; filename="A551A700-46D4-470A-86E7-52AD2B445847.dat"
Content-Type: application/octet-stream

/// FILE DATA
--B0EC8D07-EBF1-4EA7-966C-E492A9F2C36E--
