Spring Controller @RequestBody with file upload is it possible?

Question

I have a Controller like this and I want to submit a form with file uploading as well as some form data like label as shown below. Also, I want to do that using @RequestBody

Answer 1

I couldn't find a way to use @RequestBody.

However, you can do something like this:

@RequestMapping(value = "/uploadStuff", method = RequestMethod.POST)
public MyViewDto doStuff(@RequestPart("json") @Valid MyDto dto,
                         @RequestPart("file") MultipartFile file) { ... }

You can test it like this:

MockMultipartFile jsonFile = new MockMultipartFile("json", "",
            "application/json", "{}".getBytes());
MockMultipartFile dataFile = new MockMultipartFile("file", "foo.zip", "application/octet-stream", bytes);

mockMvc.perform(fileUpload("/uploadStuff")
            .file(dataFile)
            .file(jsonFile))
            .andExpect(status().isOk());
