Question

我正在尝试使用SQS使用者配置SNS生产者，该使用者使用Spring引导应用程序构建。我尝试利用Spring云并仅使用JMS API，但两种方法似乎都无法让我的使用者将消息转换为我可以阅读的方式。使用Spring cloud时，我收到一条错误消息，指出“有效载荷不是有效的通知。下面的代码：非常感谢任何帮助

SNS配置：

@Bean
public AmazonSNS snsClient() {
     AmazonSNS snsClient = AmazonSNSClientBuilder.standard()
          .withEndpointConfiguration(<endpoint-stuff)).build();
    return snsClient;
}

@Bean
public NotificationMessagingTemplate notificationMessagingTemplate(
        AmazonSNS amazonSNS) {
    return new NotificationMessagingTemplate(amazonSNS);
}

生产者代码：

@Autowired
NotificationMessagingTemplate messagingTemplate;

public void send() throws Exception {

    MessageDto message = new MessageDto();
    message.setMessageA("Hello");
    message.setMessageB("Again");

    messagingTemplate.sendNotification("my_topic",message,"Test");    
}

SQS使用者配置：

@Bean
public SimpleMessageListenerContainer simpleMessageListenerContainer() 
 {
    SimpleMessageListenerContainer msgListenerContainer = 
     simpleMessageListenerContainerFactory()
            .createSimpleMessageListenerContainer();
    msgListenerContainer.setMessageHandler(queueMessageHandler());
    return msgListenerContainer;
}

@Bean
public SimpleMessageListenerContainerFactory 
    simpleMessageListenerContainerFactory() {
    SimpleMessageListenerContainerFactory msgListenerContainerFactory = 
    new SimpleMessageListenerContainerFactory();
    msgListenerContainerFactory.setAmazonSqs(amazonSQSClient());
    return msgListenerContainerFactory;
}


@Bean
public QueueMessageHandler queueMessageHandler() {
    QueueMessageHandlerFactory queueMsgHandlerFactory = new 
    QueueMessageHandlerFactory();
    queueMsgHandlerFactory.setAmazonSqs(amazonSQSClient());
    QueueMessageHandler queueMessageHandler = 
      queueMsgHandlerFactory.createQueueMessageHandler();
    //List<HandlerMethodArgumentResolver> list = new ArrayList<>();
    //HandlerMethodArgumentResolver resolver = new 
    //PayloadArgumentResolver(new MappingJackson2MessageConverter());
    //list.add(resolver);
    //queueMessageHandler.setArgumentResolvers(list);
    return queueMessageHandler;


}




@Lazy
@Bean(name = "amazonSQS", destroyMethod = "shutdown")
public AmazonSQSAsync amazonSQSClient() {
    AwsClientBuilder.EndpointConfiguration endpointConfiguration = new 
    AwsClientBuilder.EndpointConfiguration(
            "<url>, "<region");
    AmazonSQSAsync awsSQSAsync = 

    AmazonSQSAsyncClientBuilder.standard()
    .withEndpointConfiguration(endpointConfiguration)
           .build();
    return awsSQSAsync;
}

SQS侦听器：

@SqsListener(value = "my_queue", deletionPolicy = 
 SqsMessageDeletionPolicy.ON_SUCCESS)
public void consume(final @NotificationMessage MessageDto event) {
    LOGGER.info("Message received {} 
         {}",event.getMessageA(),event.getMessageB());
}

堆栈跟踪：

Caused by: 
org.springframework.messaging.converter.MessageConversionException: 
Payload: '<payload here>' is not a valid notification
at 
org.springframework.cloud.aws.messaging.support.
converter.NotificationRequestConverter.fromMessage

aws sns到sqs，消息未转换
