maybe this can be helpfull for you

    import java.awt.Graphics2D
    import java.awt.image.BufferedImage

    import javax.imageio.ImageIO
    import javax.imageio.stream.ImageInputStream
    import javax.imageio.stream.MemoryCacheImageInputStream

    class xyzClass {
        def zabcdef(){
            org.springframework.web.multipart.commons.CommonsMultipartFile multipartfile = request.getFile('picture')
            if (!multipartfile || multipartfile.getContentType() != 'image/jpeg') {
                render("${message(code:'error.wrong.file.type')}: jpeg")
                return;
            }

            ImageInputStream iis = new MemoryCacheImageInputStream(multipartfile.getInputStream())
            BufferedImage image = ImageIO.read(iis)

            storeImage(image,"foto")
        }

    }



    private storeImage(BufferedImage image, String name) {
        ByteArrayOutputStream os = new ByteArrayOutputStream()
        ImageIO.write(image, "jpg", os)
        byte[] buf = os.toByteArray()
        InputStream is = new ByteArrayInputStream(buf)
        //store
    }
