Google App Engine 不支持视觉 api Runtime.addShutdownHook 错误
Google App Engine does not support vision api Runtime.addShutdownHook error
我的代码看起来像抛出了我不知道的异常：
@ApiMethod(name = "analyzeImage")
public Message analyzeImage(@Named("imgURL") String imgURL) {
try {
GoogleCredential credential = GoogleCredential.getApplicationDefault();
ImageAnnotatorClient vision = ImageAnnotatorClient.create();
// The path to the image file to annotate
String fileName = imgURL;
// Reads the image file into memory
Path path = Paths.get(fileName);
byte[] data = Files.readAllBytes(path);
ByteString imgBytes = ByteString.copyFrom(data);
// Builds the image annotation request
List<AnnotateImageRequest> requests = new ArrayList<>();
Image img = Image.newBuilder().setContent(imgBytes).build();
Feature feat = Feature.newBuilder().setType(Type.LABEL_DETECTION).build();
AnnotateImageRequest request = AnnotateImageRequest.newBuilder()
.addFeatures(feat)
.setImage(img)

// Performs label detection on the image file
BatchAnnotateImagesResponse response = vision.batchAnnotateImages(requests);
List<AnnotateImageResponse> responses = response.getResponsesList();

运行 api 资源管理器中的这个抛出：

根据 Google 的回复，这是 google 应用引擎和 grpc 之间与 google 视觉
通信的已知兼容性问题
我在 AppEngine 上遇到了同样的问题，当我转向 Compute Engine 时，我在 tomcat.
上遇到了类似的问题
对于旧库，我对 AppEngine 没有任何问题，我建议同时使用它：https://developers.google.com/api-client-library/java/apis/vision/v1
Google App Engine 在 Java 7 中不支持 Runtime.addShutdownHook，但在 Java 8 中支持。在 github.
上查看
如何为 Google App Engine 标准环境迁移到 Java 8？
1. 在你的 appengine-web.xml 添加
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
...
<runtime>java8</runtime>
</appengine-web-app>
2。在你的 pom.xml 添加
<project>
...
<properties>
...
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
</project>
完成。现在它应该工作了。
