SQSListener 不使用队列中的消息

Question

我看不到@SqsListener 使用的 SQS 队列中的消息

import org.springframework.cloud.aws.messaging.listener.annotation.SqsListener; //others

@Component
public class Consumer{
  private static final Logger logger = LoggerFactory.getLogger(Consumer.class);

  @SqsListener(value = "TEST-MY-QUEUE")
  public void receiveMessage(String stringJson)  {
    System.out.println("***Consuming message: " + stringJson);
    logger.info("Consuming message: " + stringJson);
  }

}

我的配置（我在这里打印客户端队列，我可以 deffo 发现我想要使用的队列 - TEST-MY-QUEUE 。它在该区域正确打印 URL 。我也能够在 regionProvider

中查看正确加载的区域（与队列相同）

@Configuration

public class AwsConfiguration { 

  @Bean
  @Primary
  AmazonSQSAsync sqsClient() {
    AmazonSQSAsync amazonSQSAsync = AmazonSQSAsyncClientBuilder.defaultClient();
    System.out.println("Client queues = " + amazonSQSAsync.listQueues()); //The queue I want to consume is here
    return amazonSQSAsync;
  }

  @Bean
  AwsRegionProvider regionProvider() {
    DefaultAwsRegionProviderChain defaultAwsRegionProviderChain = new DefaultAwsRegionProviderChain();
    System.out.println("Region = " + defaultAwsRegionProviderChain.getRegion());
    return defaultAwsRegionProviderChain;
  }

@Bean
public SimpleMessageListenerContainer simpleMessageListenerContainer(AmazonSQSAsync amazonSQSAsync, QueueMessageHandler queueMessageHandler) {
    
    SimpleMessageListenerContainer simpleMessageListenerContainer = new SimpleMessageListenerContainer();
    simpleMessageListenerContainer.setAmazonSqs(amazonSQSAsync);
    simpleMessageListenerContainer.setMessageHandler(queueMessageHandler);
    simpleMessageListenerContainer.setMaxNumberOfMessages(10);
    simpleMessageListenerContainer.setTaskExecutor(threadPoolTaskExecutor());
    return simpleMessageListenerContainer;
  }

  @Bean
  public QueueMessageHandler queueMessageHandler(AmazonSQSAsync amazonSQSAsync) {
    QueueMessageHandlerFactory queueMessageHandlerFactory = new QueueMessageHandlerFactory();
    queueMessageHandlerFactory.setAmazonSqs(amazonSQSAsync);
    QueueMessageHandler queueMessageHandler = queueMessageHandlerFactory.createQueueMessageHandler();
    return queueMessageHandler;
  }

  public ThreadPoolTaskExecutor threadPoolTaskExecutor() {
    ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
    executor.setCorePoolSize(10);
    executor.setMaxPoolSize(10);
    executor.initialize();
    return executor;
  }

和pom.xml（Java11，spring开机，spring云aws）


        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>2.5.6</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-aws-core</artifactId>

        </dependency>

        <dependency>

            <artifactId>spring-cloud-aws-autoconfigure</artifactId>
            <version>2.2.6.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-bootstrap</artifactId>
            <version>3.0.3</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-aws</artifactId>
            <version>2.2.6.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-aws-messaging</artifactId>
            <version>2.2.6.RELEASE</version>
        </dependency>

我注意到这里的问题非常相似，我将 pom.xml 中的依赖项更改为 spring-cloud-starter-aws-messaging 但没有为我修复。我仔细检查了名称（队列、注释），一切似乎都很好当我运行我的应用程序启动正常但我没有看到任何日志或异常。没有一条消息被消费。我错过了什么？

谢谢

Answer 1

您正在使用第三方 API。要从 Java 项目调用 Amazon Simple Queue Service (SQS)，请使用官方 AWS SDK for Java V2。如果您不知道如何使用此 SDK，请参阅此开发指南：

Developer guide - AWS SDK for Java 2.x

有关 AWS SQS 的特定信息，请参阅：

Working with Amazon Simple Queue Service

这有指向 AWS Github 的链接，您可以在其中找到 POM 依赖项、代码等。

最后是配置问题（使用凭据）

在application.yml

credentials:
  useDefaultAwsCredentialsChain: true #Will use credentials in /.aws

然后在创建 AmazonSQSAsync 的 AWSConfig class 中，让它使用该配置

public AmazonSQSAsync amazonSQSAsync() {
  DefaultAWSCredentialsProviderChain defaultAWSCredentialsProviderChain = new DefaultAWSCredentialsProviderChain();
  return AmazonSQSAsyncClientBuilder.standard().withRegion(region)
            .withCredentials(defaultAWSCredentialsProviderChain)
            .build();

SQSListener 不使用队列中的消息
