            @RequestParam(value="childFile") String childFile, @RequestParam(value="file") MultipartFile file) {

        ObjectMapper mapper = new ObjectMapper();
        Child child;
        try {
            child=mapper.readValue(childFile, Child.class);
            Child createdChild=childRepo.save(child);
            if(createdChild!=null)
            {
             childService.createChildPhoto(file, createdChild.getId());
            }
            return ResponseEntity.ok("child created");
        } catch (IOException e1) {
            e1.printStackTrace();

In postman, try changing the content type of `childFile` from `Text` to `application/json`.. I doubt it won't make difference but I would like to see the error. — harshavmb, Feb 27 '18 at 08:20

So I found a solution to this problem..The issue was with postman when I remove content-type header it works fine,Postman insert header by itself

You are using form data with a simple request param, that's not how it works. If you are trying to send the json and file together, make sure "childFile"'s content type is "application/json" and receive it by request body with annotation @RequestPart, and mapping produces should be "multipart/form-data", then it will do the job.

Now it gives the following error `Could not parse multipart servlet request; nested exception is javax.servlet.ServletException: org.apache.tomcat.util.http.fileupload.FileUploadBase$InvalidContentTypeException: the request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is application/json"` – SFAH Feb 27 '18 at 07:59
Maybe the postman cannot do what i wanted, it's not a mixed stream. Actually, i just set the content-type in the header to 'undefined', but the blob of 'childFile' is application/json, it's part of the form data, this is what i would do in my code: ``` var fd = new FormData(); fd.append('file', yourfile); fd.append('childFile', new Blob([JSON.stringify(fileInfo)], { type: "application/json" })); ``` I donnot know what exactlly the postman can do. – Snart Feb 28 '18 at 03:54
