How to detect Spring MultipartFile paramter in ApiModel annotated POJOs and show file upload button in Swagger-UI

[roseoxhu]

I'm using springfox v2.5 for springMVC project, i have an api method expect user upload an attach file.

if i declare MultipartFile in method parameter, springfox can parse correctly and show file upload button,

@RequestMapping(value = "/upload", method = RequestMethod.POST)
@ApiOperation(value="upload attach file", httpMethod = "POST")
public String upload(HttpSession session, HttpServletRequest request,
           @RequestParam MultipartFile attachment) {
        // bala bala
}

but i want a good model structure, move the MultipartFile into a POJO

@ApiModel(description=“POJO model”)
public class Pojo {
      @ApiModelProperty(value = "attach file", required = true)
       private MultipartFile attachment;
}

then modify API method:

@RequestMapping(value = "/upload", method = RequestMethod.POST)
@ApiOperation(value="upload attach file", httpMethod = "POST")
public String upload(HttpSession session, HttpServletRequest request,
           @ModelAttribute Pojo pojo) {
        // bala bala
}

in this case definition, springfox cannot known Pojo's MultipartFile parameter, so the swagger-ui dosen't show the file upload buttion.
