Spring Cloud PubSub未正确关闭错误

Question

我正在尝试实现Spring Cloud Pub/Sub，我遵循了指南，但如何降低异常，这使它开始消耗高级别的处理，我研究了很多，他们说要将参数设置为awaitTerminated，但我找不到如何定义这个参数。

版本：

<spring-cloud-gcp.version>2.0.4</spring-cloud-gcp.version>
<spring-cloud.version>2020.0.4</spring-cloud.version>

豆类

@Bean
public DefaultPublisherFactory defaultPublisherFactory(GcpProjectIdProvider gcpProjectIdProvider) {
DefaultPublisherFactory factory = new DefaultPublisherFactory(gcpProjectIdProvider);
factory.setEnableMessageOrdering(true);
factory.setEndpoint("us-east1-pubsub.googleapis.com:443");
return factory;
}
@Bean
@ServiceActivator(inputChannel = "pubSubOutputChannel")
public MessageHandler messageSender(PubSubTemplate pubsubTemplate) {
PubSubMessageHandler adapter = new PubSubMessageHandler(pubsubTemplate, "noMatter");
adapter.setFailureCallback((cause, message) ->
System.err.println("Fail to send message " + message)
);
return adapter;
}
@MessagingGateway(defaultRequestChannel = "pubSubOutputChannel")
public interface PubSubOutboundGateway {
void sendToPubSub(@Header(GcpPubSubHeaders.TOPIC) String topic, String payload);
}

Answer 1

我尽可能简单地解决了这个问题，最终删除了BeanDefaultPublisherFactory并解决了问题。

Answer 2

我收到这个错误是因为我没有关闭SubscriptionAdminClient。我通过使用try-with-resources块中的对象来解决问题：

try (SubscriptionAdminClient subscriptionAdminClient = createSubscriptionAdminClient()) {
subscriptionAdminClient.createSubscription(...);
...
} catch (IOException e) {
throw new RuntimeException("Failure...", e);
}
