Question

我正试图在google api中使用google vision，但是我遇到了以下问题：

jun 07,2017 8:50:00 AM io.grpc.internal.ChannelExecutor drain ADVERTÊNCIA：Runnable在ChannelExecutor中抛出异常 java.lang.IllegalArgumentException：Jetty ALPN / NPN还没有配置正确。在 io.grpc.netty.GrpcSslContexts.selectApplicationProtocolConfig（GrpcSslContexts.java:174）在io.grpc.netty.GrpcSslContexts.configure（GrpcSslContexts.java:151）在io.grpc.netty.GrpcSslContexts.configure（GrpcSslContexts.java:139）在io.grpc.netty.GrpcSslContexts.forClient（GrpcSslContexts.java:109）在 io.grpc.netty.NettyChannelBuilder.createProtocolNegotiatorByType（NettyChannelBuilder.java:335）在 io.grpc.netty.NettyChannelBuilder.createProtocolNegotiator（NettyChannelBuilder.java:308）在 io.grpc.netty.NettyChannelBuilder $ NettyTransportFactory $ DynamicNettyTransportParams.getProtocolNegotiator（NettyChannelBuilder.java:499）在 io.grpc.netty.NettyChannelBuilder $ NettyTransportFactory.newClientTransport（NettyChannelBuilder.java:448）在 io.grpc.internal.CallCredentialsApplyingTransportFactory.newClientTransport（CallCredentialsApplyingTransportFactory.java:61）在 io.grpc.internal.InternalSubchannel.startNewTransport（InternalSubchannel.java:209）在 io.grpc.internal.InternalSubchannel.obtainActiveTransport（InternalSubchannel.java:186）在 io.grpc.internal.ManagedChannelImpl $ SubchannelImplImpl.obtainActiveTransport（ManagedChannelImpl.java:806）在 io.grpc.internal.GrpcUtil.getTransportFromPickResult（GrpcUtil.java:568）在 io.grpc.internal.DelayedClientTransport.reprocess（DelayedClientTransport.java:296）在 io.grpc.internal.ManagedChannelImpl $ LbHelperImpl $ 5.run（ManagedChannelImpl.java:724）在io.grpc.internal.ChannelExecutor.drain（ChannelExecutor.java:87）在 io.grpc.internal.ManagedChannelImpl $ LbHelperImpl.runSerialized（ManagedChannelImpl.java:715）在 io.grpc.internal.ManagedChannelImpl $ NameResolverListenerImpl.onUpdate（ManagedChannelImpl.java:752） at io.grpc.internal.DnsNameResolver $ 1.run（DnsNameResolver.java:174）在 java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1142）在 java.util.concurrent.ThreadPoolExecutor中的$ Worker.run（ThreadPoolExecutor.java:617）在java.lang.Thread.run（Thread.java:745）

我正在尝试运行api自己的示例代码，如下所示：

public class QuickstartSample {
    public static void main(String... args) throws Exception {
        // Instantiates a client
        ImageAnnotatorClient vision = ImageAnnotatorClient.create();

        // The path to the image file to annotate
        String fileName = "./resources/wakeupcat.jpg";

        // 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).build();
        requests.add(request);

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

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

            for (EntityAnnotation annotation : res.getLabelAnnotationsList()) {
                annotation.getAllFields().forEach((k, v) -> System.out.printf("%s : %s\n", k, v.toString()));
            }
        }
    }
}

我正在使用以下依赖项：

    <dependency>
        <groupId>com.google.apis</groupId>
        <artifactId>google-api-services-vision</artifactId>
        <version>v1-rev357-1.22.0</version>
    </dependency>
    <dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>google-cloud-vision</artifactId>
        <version>0.17.2-beta</version>
    </dependency>

有没有人遇到过这个问题？

我实际上发现要运行api，你必须在Web上下文中并且还要在Jetty服务器上运行应用程序

IllegalArgumentException：尚未正确配置Jetty ALPN / NPN
