The call to the newer version of com.google.cloud.pubsub.spi.v1.Publisher.publish(pubsubMessage).get()
is hanging forever. I'm not sure what the problem is.
Code snippet:
com.google.cloud.pubsub.spi.v1.Publisher publisher = Publisher.defaultBuilder(TopicName.parse("projects/" + projectId + "/topics/" + topicName))
.setChannelProvider(TopicAdminSettings
.defaultChannelProviderBuilder()
.setCredentialsProvider(FixedCredentialsProvider.create(ServiceAccountCredentials.fromStream(new FileInputStream(keyFile))))
.build())
.build();
ApiFuture<String> messageIdFuture = publisher.publish(pubsubMessage);
messageIdFuture.get() // HANGS FOREVER!!
The older API works fine where we do:
GoogleCredential credential = new GoogleCredential.Builder()
.setTransport(new NetHttpTransport())
.setJsonFactory(JSON_FACTORY)
.setServiceAccountId(serviceAccount)
.setServiceAccountScopes(Arrays.asList(PubsubScopes.PUBSUB))
.setServiceAccountPrivateKeyFromP12File(new File(keyFile))
.build();
Pubsub pusub = new Pubsub.Builder(transport, JSON_FACTORY, credential).setApplicationName("bigquery").build();
PubsubMessage pubsubMessage = new PubsubMessage();
pubsubMessage.encodeData(message.getBytes());
PublishRequest publishRequest = new PublishRequest();
publishRequest.setMessages(Arrays.asList(pubsubMessage));
pubsub.projects().topics().publish(outputTopic, publishRequest).execute();
Can somebody point out what am I missing?
This may be because you have not configured subscription for the topic or given proper permissions in the GCP console.
It is required to have a subscription attached to the topic. Also make sure you give the correct permissions in the console. Note that you give this
"client_email" : (an auto-generated email id)
auto-generated email id with admin subscriber permissions in the console.
You will get this field in your projectname.json credentials file while configuring.
Hope it helps.
我不知道为什么,但是一旦我为guava添加了一个编译依赖项,就不再在get调用上挂起了。
compile group: 'com.google.guava', name: 'guava', version: '23.0'
For us, when we removed guava dependency, it worked. We are using following version for publishing: com.google.cloud:google-cloud-pubsub:1.33.0
