AWS SQS - MessageConsumer 在一段时间后停止接收消息

Question

我的应用程序将侦听器注册到 SQS 队列（队列本身由 SNS 主题填充）。 当我启动应用程序时，消息使用者按预期工作，但过了一会儿它停止接收任何消息。会不会是消费者过一段时间就关机了？

建议或意见将不胜感激。

SQS连接：

@Bean
public SQSConnection amazonSQSConnection(
      @Value("${aws.access.key}") String accessKey,
      @Value("${aws.secret.key}") String secretKey) throws JMSException {


BasicAWSCredentials basicAWSCredentials = new BasicAWSCredentials(accessKey, secretKey);
AmazonSQSClientBuilder client = AmazonSQSClientBuilder
        .standard()
        .withRegion(Regions.GovCloud)
        .withCredentials(new AWSStaticCredentialsProvider(basicAWSCredentials));
SQSConnectionFactory connectionFactory = new SQSConnectionFactory(new ProviderConfiguration(), client);

return connectionFactory.createConnection();
}

消费者：

 @Bean
 public MessageConsumer workOrderChangeConsumer(
      SQSConnection connection,
      WorkOrderKittingService workOrderKittingService,
      AuthenticationProvider authProvider,
      @Value("${app.user.name}") String appUserName,
      @Value("${aws.sqs.workorder.change.queue}") String woChangeQueue) throws JMSException {

Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);
Queue queue = session.createQueue(woChangeQueue);

WorkOrderChangeIngestor workOrderChangeIngestor = new WorkOrderChangeIngestor(
        workOrderKittingService,
        authProvider,
        appUserName);

MessageConsumer consumer = session.createConsumer(queue);
consumer.setMessageListener(workOrderChangeIngestor);
connection.start();

return consumer;
}

您正在尝试自己管理连接生命周期。

我建议您使用 spring-cloud-aws

让 spring 为您管理

https://docs.spring.io/spring-cloud-aws/docs/2.2.3.RELEASE/reference/html/#receiving-a-message

可以通过注解创建监听器：

@Component
public class MyMessageHandler {

    @SqsListener("queueName")
    void handle(String message) {
        ...
        throw new MyException("something went wrong");
    }

    @MessageExceptionHandler(MyException.class)
    void handleException(MyException e) {
        ...
    }
}
