Multipart File upload Spring Boot

Question

Im using Spring Boot and want to use a Controller to receive a multipart file upload. When sending the file I keep getting the error 415 unsupported content type

Answer 1

@RequestMapping(value="/add/image", method=RequestMethod.POST)
public ResponseEntity upload(@RequestParam("id") Long id, HttpServletResponse response, HttpServletRequest request)
{   
    try {
        MultipartHttpServletRequest multipartRequest=(MultipartHttpServletRequest)request;
        Iterator it=multipartRequest.getFileNames();
        MultipartFile multipart=multipartRequest.getFile(it.next());
        String fileName=id+".png";
        String imageName = fileName;

        byte[] bytes=multipart.getBytes();
        BufferedOutputStream stream= new BufferedOutputStream(new FileOutputStream("src/main/resources/static/image/book/"+fileName));;

        stream.write(bytes);
        stream.close();
        return new ResponseEntity("upload success", HttpStatus.OK);

    } catch (Exception e) {
        e.printStackTrace();
        return new ResponseEntity("Upload fialed", HttpStatus.BAD_REQUEST);
    }   
}
