Is there any way in Hybris to obtain all the bytes from a MediaModel ? When I want to instantiate a PdfReader , I need to pass either the Path of the File OR the ByteArrayInputStream. How can I transform the MediaModel into a Byte Array?

推荐答案

您可以使用MediaService

You can use MediaService

@Resource
private MediaService mediaService;
//...
final MediaModel mediaModel= mediaService.getMedia("mediaName");
final InputStream inputStream = mediaService.getStreamFromMedia(mediaModel);

然后，您可以传递InputStream或将其转换为所需的格式，例如 ByteArrayInputStream

Then you can pass InputStream or converting it to the format you want like ByteArrayInputStream

您还可以像此

byte[] bytes = IOUtils.toByteArray(is);
