To display images we'll have to return an unwrapped byte[] and specify the content type of the response as "image/.."
And this happens either by using HttpServletResponse or a simple spring endpoint way.

@ApiOperation(value = "To display a product image using its id",produces = "image/jpeg")
@GetMapping(value = "/image")
@ResponseStatus(HttpStatus.OK)
public void getImage(@RequestParam("id") Long id, HttpServletResponse response) {
    String image = repository.findById(id)
            .orElseThrow(() -> new NotFoundException(id))
            .getImage();
    response.setContentType("image/jpeg"); 
    IOUtils.copy(is, response.getOutputStream());
}

@ApiOperation(value = "To display a product image using its id", produces = "image/jpeg")
@GetMapping(value = "/image",produces =MediaType.IMAGE_JPEG_VALUE)
@ResponseStatus(HttpStatus.OK)
public byte[] getImage(@RequestParam("id") Long id) {
    String image = repository.findById(id)
            .orElseThrow(() -> new NotFoundException(id))
            .getImage();
    return ImageMapper.INSTANCE.toByteArrayUnWrapped(image);
}
