java - Graylog Google Pub/Sub 输出插件问题

标签 java google-cloud-pubsub graylog graylog3

我们正在构建一个 Graylog 输出插件，用于将数据发送到 Google PubSub。这是我们编写的代码，灵感来自 google pubsub 提供的样板代码( this 和 this )

try (InputStream credential = new FileInputStream(Objects.requireNonNull(config.getString(CK_CREDENTIAL_FILE)))) {
                CredentialsProvider credentialsProvider = FixedCredentialsProvider
                        .create(ServiceAccountCredentials.fromStream(credential));
                // endpoint can be set here
                publisher = Publisher.newBuilder(topicName).setCredentialsProvider(credentialsProvider).build();

                ByteString finalData = ByteString.copyFromUtf8(String.valueOf(obj));
                PubsubMessage pubsubMessage = PubsubMessage.newBuilder()
                        .setData(finalData)
                        .build();
                ApiFuture<String> future = publisher.publish(pubsubMessage);
                messageIdFutures.add(future);
                ApiFutures.addCallback(
                        future,
                        new ApiFutureCallback<String>() {

                            @Override
                            public void onFailure(Throwable throwable) {
                                if (throwable instanceof ApiException) {
                                    ApiException apiException = ((ApiException) throwable);
                                    // details on the API exception
                                    System.out.println(apiException.getStatusCode().getCode());
                                    System.out.println(apiException.isRetryable());
                                }
                                System.out.println("Error publishing message : " + String.valueOf(obj));
                            }

                            @Override
                            public void onSuccess(String messageId) {
                                // Once published, returns server-assigned message ids (unique within the topic)
                                System.out.println(messageId);
                            }
                        },
                        MoreExecutors.directExecutor());
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (publisher != null) {
                try {
                    try {
                        publisher.shutdown();
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                    publisher.awaitTermination(1, TimeUnit.MINUTES);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }

运行时，我们收到以下错误堆栈:-

我们甚至查看了 grpc-java github repo 但似乎无法找出问题所在。我们在通信中没有使用 grpc，但我们认为 google pubsub java 模块内部正在使用它。

任何帮助将不胜感激。提前致谢。

最佳答案

我也遇到了同样的问题， 我的应用程序是用scala(用sbt)开发的，但用maven也是一样的。 为了解决这个问题，我改变了我的依赖关系: 

libraryDependencies += "com.google.cloud" % "google-cloud-pubsub" % "1.75.0"
libraryDependencies += "com.google.api-client" % "google-api-client" % "1.30.5"
libraryDependencies += "com.google.cloud" % "google-cloud-core-grpc" % "1.91.3"

对于代码，只需保留创建谷歌凭证对象的默认方式:

def publishMessages(projectId : String, topic : String, event : String): Unit = { 
    val topicName = ProjectTopicName.of(projectId, topic)
    var publisher : Publisher = null
    val messageIdFutures = new util.ArrayList[ApiFuture[String]]
    try {
      val credentials = GoogleCredentials.fromStream(new FileInputStream(creds)).createScoped(
        java.util.Arrays.asList("https://www.googleapis.com/auth/cloud-platform")
      )
      publisher = Publisher.newBuilder(topicName)
        .setCredentialsProvider(FixedCredentialsProvider.create(credentials)).build

      val payload = ByteString.copyFromUtf8(event)
      val pubsubMessage = PubsubMessage.newBuilder.setData(payload).build
      val messageIdFuture = publisher.publish(pubsubMessage)
      messageIdFutures.add(messageIdFuture)
}
