Spring integration 由于bean初始化不正确，Spring cloud AWS kinesis流绑定器无法启动

我正试图用下面的代码运行这个简单的运动信息消费者。这是应用程序中唯一的类

我面临此错误，因为我已更新到最新快照版本的kinesis binder

    @SpringBootApplication
    @RestController
    @EnableBinding(Sink.class)
    @EnableAutoConfiguration
    public class ProducerApplication {



      public static void main(String[] args) {
        SpringApplication.run(ProducerApplication.class, args);
      }

      @StreamListener(Sink.INPUT)
      public void listen(String message) {
        System.out.println("Message has been received"+message);
      }

    }

应用程序yml

server.port: 8081


spring:
  cloud:
    stream:
      bindings:
        input:
          destination: my.sink
          content-type: application/json




cloud:
  aws:
    region:
      static: us-east-1
    credentials:
      accessKey: <accessKey>
      secretKey: <secretKey>

我得到了bean初始化异常，在创建bean

dynamodbmetadastore

时似乎出现了问题

此错误是在更新到最新快照版本的kinesis binder后开始的

您能检查一下是否有问题。

我刚刚解决了这个问题：

问题是，当我们在DynamoDB中已经有了一个表时，我们只是从

afterPropertiesSet（）

返回，将

初始化的

保留为

false

最新的

BUILD-SNAPSHOT

现在应该可以工作了。

您能在Git Hub上的某个地方与我们分享一个简单的项目吗？另外，我不知道

cloud.aws.kinesis.endpoint

configuration属性。那是什么？谁以及如何使用它？@ArtemBilan感谢您的关注。我已经在这里添加了示例项目，请检查并帮助此属性cloud.aws.kinesis.endpoint没有任何意义。谢谢你。现在我得到这个错误，是因为访问问题。c、 a.s.d.AmazonDynamoDBLockClient:无法获取锁，因为与DDB com.amazonaws.services.dynamodbv2.model.AmazondynamodException:用户：arn:aws:iam:：123:用户/aws kinesis开发人员无权在资源上执行：dynamodb:GetItem：arn:aws:dynamodb:us-east-1:123:table/SpringIntegrationLockRegistry（服务：Amazondynamodv2；状态代码：400；错误代码：AccessDeniedException；请求ID:R5S2G137V3NN625GD52ASOHG4BV4KQNSO5AEMVJF66Q9AAJG）用户：arn:aws:iam:：123:用户/aws运动开发人员无权执行：dynamodb:GetItem on resource:。这已经超出了Spring Cloud Stream Kinesis Binder项目的责任范围。您需要向use

GetItem

授予这些权限。在授予足够的权限后，它就工作了。非常感谢。
