java - 有人可以提供 spring-integration-aws SQS 用法的示例吗？

Question

Here是 spring-integration-aws 项目。他们提供了有关 Inbound Channle 适配器的示例:

@SpringBootApplication
public static class MyConfiguration {

    @Autowired
    private AmazonSQSAsync amazonSqs;

    @Bean
    public PollableChannel inputChannel() {
        return new QueueChannel();
    }

    @Bean
    public MessageProducer sqsMessageDrivenChannelAdapter() {
        SqsMessageDrivenChannelAdapter adapter = new SqsMessageDrivenChannelAdapter(this.amazonSqs, "myQueue");
        adapter.setOutputChannel(inputChannel());
        return adapter;
    }
}

好了，Channel 和SqsMessageDrivenChannelAdapter 都定义好了，但是接下来呢？假设我有这样的 spring bean:

import com.amazonaws.services.sqs.model.Message;

@Component
public class MyComponent {
    public void onMessage(Message message) throws Exception {
        //handle sqs message
    }
} 

1. 如何告诉 spring 将所有消息从myQueue 传递给这个 组件？
2. 是否有任何额外的配置来处理消息 一？例如在收到消息 SQS 后将它们标记为 处理并且它们对其他客户端不可见，所以它是 只需要获取一条消息，然后处理并获取下一条消息。做 此行为默认启用？

您应该阅读 Spring Integration Reference Manual .

@Component
public class MyComponent {

    @ServiceActivator(inputChannel = "inputChannel")
    public void onMessage(Message message) throws Exception {
        //handle sqs message
    }

}
