如何利用 Java 函数充分利用云平台上的人工智能资源？

public class ImageClassification implements HttpFunction {

    @Override
    public void service(HttpRequest request, HttpResponse response)
            throws IOException {
        // 从请求中提取图像 URL
        String url = request.getFirstQueryParameter("url").orElse("");

        // 创建 ImageAnnotatorClient 实例
        try (ImageAnnotatorClient client = ImageAnnotatorClient.create()) {

            // 根据 URL 构建 Image 对象
            ImageSource imgSource = ImageSource.newBuilder().setImageUri(url).build();
            Image img = Image.newBuilder().setSource(imgSource).build();

            // 执行图像分类
            List<AnnotateImageResponse> responses =
                    client.batchAnnotateImages(Collections.singletonList(img)).getResponsesList();

            // 从响应中提取分类结果
            String description = responses.get(0).getAnnotationResults(0).getDescription();

            // 将结果写入响应正文
            response.getWriter().write(description);
        }
    }
}
