Looking good. But as a burned kind def. want to add a unit test before merging. Will do that in the next days

[derjust]

Thanks for the PR!

@derjust ya np .. was in a hurry couldn't add the test case using this custom implementation right now for my existing project .. will be great if you could merge the fix once approved in the 4.5.x branch as well .

[derjust]

Merged in branch issue_91 to add unit test.
Thanks for the PR!

HI @derjust one more thing I guess needs to be changed is getOverriddenTableName whcih will give NPE if dynamoDbconfig is not provided . Can we make the method below Public rather than introducing the new method we have for the mapper as config could be required getOverriddenTableName
DynamoDBTemplate(AmazonDynamoDB amazonDynamoDB, DynamoDBMapperConfig dynamoDBMapperConfig, DynamoDBMapper dynamoDBMapper)

[derjust]

absolutely doable. Any chance to get access to your (maybe simplified) complete scenario to add it as a knot test?

Hi in my case I am adding a DynamoDbTemplate with a configured encryption transformer as below .. Currently using a custom DynamodBTemplate class .

return new DynamoDBTemplate(amazonDynamoDB, this.dynamoDBMapperConfig(), new DynamoDBMapper(amazonDynamoDB,
            this.dynamoDBMapperConfig(), new AttributeEncryptor(new DirectKmsMaterialProvider(awsKMS, kmsKey))));
