Answer 1

I have used the spring boot and rest where this following code will work if you are using latest version of spring i.e.,Spring 4.1

@RequestMapping(value = "/image", method = RequestMethod.GET)
    @ResponseBody
    public ResponseEntity<InputStreamResource> getImage() {
        GridFSDBFile gridFsFile = App.getImageResponse();

        return ResponseEntity.ok()
                .contentLength(gridFsFile.getLength())
                .contentType(MediaType.parseMediaType(gridFsFile.getContentType()))
                .body(new InputStreamResource(gridFsFile.getInputStream()));
    }
