java - 无法在 aws 中连接到 Dax 集群

问题描述

无法在 aws ec2 实例中连接 dax 集群。已将 ec2 实例和 dax 集群的 vpc 和子网以及安全组配置为相同。仍然收到此错误

用过的

<!-- https://mvnrepository.com/artifact/com.amazonaws/amazon-dax-client -->
<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>amazon-dax-client</artifactId>
    <version>1.0.205044.0</version>
</dependency>

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-dynamodb</artifactId>
    <version>1.12.106</version>
</dependency>

DynamoBeanConfig 是

public AmazonDynamoDB amazonDynamoDBDax() {

        return AmazonDaxClientBuilder.standard()
                .withRegion(Regions.fromName(region)).withEndpointConfiguration(daxUrl).withCredentials(new AWSStaticCredentialsProvider(amazonBasicAwsCredentails())).build()        }

使用过 spring 框架，dynamoDBMapper 我认为问题与我正在使用的 dax 客户端版本或某些网络配置有关。感谢任何建议。
