AWS SDK 2承担角色

Question

@Bean
public DynamoDbClient amazonDynamoDB() {
    final AssumeRoleRequest assumeRoleRequest = AssumeRoleRequest.builder().roleSessionName(UUID.randomUUID().toString()).roleArn("roleArn").build();
    final StsAssumeRoleCredentialsProvider  stsAssumeRoleCredentialsProvider = StsAssumeRoleCredentialsProvider.builder().refreshRequest(assumeRoleRequest).build();
    return DynamoDbClient.builder().credentialsProvider(stsAssumeRoleCredentialsProvider).region(Region.EU_WEST_1)
            .build();
}

获取错误

引起原因：org.springframework.beans.BeanInstantiationExc0019：未能实例化[software.amazon.awssdk.services.dynamodb.DynamoDbClient]：工厂方法'amazonDynamoDB'抛出异常；嵌套异常java.lang.NullPointerExc0019： STS客户端不得为空。[e-mail]/org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate（SimpleInstantiationStrategy.java:185）在[e-mail]/org.springframework.beans.factory.support.ConstructorResolver.instantiate（ConstructorResolver.java:650）...58常见帧省略造成：java.lang.NullPointerExcture： STS客户端不能为空。

Answer 1

在假设角色请求中需要设置st客户端

@Bean
@Primary
public DynamoDbClient amazonDynamoDB() {
    final AssumeRoleRequest assumeRoleRequest = AssumeRoleRequest.builder().roleSessionName(UUID.randomUUID().toString()).roleArn("roleArn").build();
    final StsClient stsClient = StsClient.builder().region(Region.EU_WEST_1).build();
    final StsAssumeRoleCredentialsProvider  stsAssumeRoleCredentialsProvider = StsAssumeRoleCredentialsProvider.builder().stsClient(stsClient).refreshRequest(assumeRoleRequest).build();
    return DynamoDbClient.builder().credentialsProvider(stsAssumeRoleCredentialsProvider).region(Region.EU_WEST_1)
            .build();
}
