Spring Boot cloud GCP无法连接到本地Google PubSub仿真器

1. src/test/resources/application.properties
2. 设置 spring.cloud.gcp.pubsub.emulator-host=localhost:8085
3. 注释您的测试类,以便Spring获取您的测试应用程序。特性:

@RunWith(SpringRunner::class)
@SpringBootTest

编辑:我创建了一个示例项目,展示了如何在测试中使用Spring和PubSub emulator(这也需要创建主题和订阅): https://github.com/nhartner/pubsub-emulator-demo

使用发布/订阅仿真器时,请使用 FixedTransportChannelProvider NoCredentialsProvider 创建 Publisher 或 Subscriber UsePubSubEmulatorSnippet.java

String hostport = System.getenv("PUBSUB_EMULATOR_HOST");
ManagedChannel channel = ManagedChannelBuilder.forTarget(hostport).usePlaintext(true).build();
TransportChannelProvider channelProvider = FixedTransportChannelProvider.create(GrpcTransportChannel.create(channel));

CredentialsProvider credentialsProvider = NoCredentialsProvider.create();

ProjectTopicName topicName = ...

// Use the channel and credentials provider when creating a Publisher or Subscriber.
Publisher publisher =
    Publisher.newBuilder(topicName)
        .setChannelProvider(channelProvider)
        .setCredentialsProvider(credentialsProvider)
        .build();
