java - Grails 2.x 和 Google Cloud Vision API“java”错误

Question

我正在使用 Google Cloud Vision API 进行一些 OCR 测试。https://cloud.google.com/vision/docs/ocr#vision_text_detection-java建议的代码工作正常。但是我需要更新一个旧的 Grails 2.5.6 应用程序来实现 OCR，我尝试使用相同的代码进行相同的测试，但产生了以下错误：

仅出于测试目的，我在 Bootstrap.groovy 中编写了建议的代码，如下所示：

import com.google.cloud.vision.v1.AnnotateImageRequest
import com.google.cloud.vision.v1.AnnotateImageResponse
import com.google.cloud.vision.v1.BatchAnnotateImagesResponse
import com.google.cloud.vision.v1.EntityAnnotation
import com.google.cloud.vision.v1.Feature
import com.google.cloud.vision.v1.Image
import com.google.cloud.vision.v1.ImageAnnotatorClient
import com.google.protobuf.ByteString

class BootStrap {

    def init = { servletContext ->
        def realPath = servletContext.getRealPath("/reports/images/")
        def fileName = "${realPath}/1.png"
        detectText(fileName)
    }
    def destroy = {
    }

    def detectText(String filePath) throws IOException {
        List<AnnotateImageRequest> requests = new ArrayList<>();

        ByteString imgBytes = ByteString.readFrom(new FileInputStream(filePath));

        Image img = Image.newBuilder().setContent(imgBytes).build();
        Feature feat = Feature.newBuilder().setType(Feature.Type.TEXT_DETECTION).build();
        AnnotateImageRequest request =
                AnnotateImageRequest.newBuilder().addFeatures(feat).setImage(img).build();
        requests.add(request);

        ImageAnnotatorClient client = ImageAnnotatorClient.create()
        BatchAnnotateImagesResponse response = client.batchAnnotateImages(requests);
        List<AnnotateImageResponse> responses = response.getResponsesList();

        for (AnnotateImageResponse res : responses) {
            if (res.hasError()) {
                System.out.format("Error: %s%n", res.getError().getMessage());
                return;
            }

            for (EntityAnnotation annotation : res.getTextAnnotationsList()) {
                System.out.format("Text: %s%n", annotation.getDescription());
                System.out.format("Position : %s%n", annotation.getBoundingPoly());
            }
        }
    }
}

我该如何解决这个问题？提前致谢。
