AWS DynamoDB Verschlüsselung kann nicht HTTP-Response Inhalt

Question

Ich verwende DirectKmsMaterialProvider von aws-DynamoDB-Verschlüsselung-java analysieren meine Daten zu verschlüsseln, gespeichert werden, um DynamoDB aber beim Aufruf mapper.save (objectToSave) ich die Fehler unter:

final EncryptionMaterialsProvider provider = new DirectKmsMaterialProvider(awskmsClient, 
        awsKMSAliasKey); 
      mapper = new DynamoDBMapper(dynamoDBClient, mapperConfig, 
        new AttributeEncryptor(provider)); 

Fehler:

com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBMappingException: com.amazonaws.AmazonServiceException: Unable to parse HTTP response content (Service: AWSKMS; Status Code: 302; Error Code: null; Request ID: null)

Answer 1

stellen Sie sicher, dass Ihre KMS Endpunkt korrekt zum Beispiel ist:

AWSKMSClient awsKMSClient = new AWSKMSClient(new InstanceProfileCredentialsProvider()); 
awsKMSClient.setEndpoint("kms.ap-southeast-1.amazonaws.com"); 

siehe http://docs.aws.amazon.com/general/latest/gr/rande.html#kms_region
