Spring Cloud AWS 2.3 is now available

Releases | Spencer Gibb | March 17, 2021 | ...

The following is a guest post from the maintainers of the Spring Cloud AWS project.

On behalf of the Spring Cloud AWS team and the community around Spring Cloud AWS, I am happy to share that we have just released Spring Spring Cloud AWS 2.3 - a version that is compatible with Spring Boot 2.4 and Spring Cloud 2020.0.

This release contains a new integration with Cognito and a bunch of small improvements, fixes, and changes that we believe will make working with Spring Cloud AWS more pleasurable.

I believe the most surprising change is that now you need to include a separate Spring Cloud AWS BOM in your pom.xml file:


Also, dependencies group ids have to be updated to io.awspring.cloud:


All classes have moved from the org.springfamework.cloud.aws to io.awspring.cloud package.

Release Notes

The most important changes organized by Spring Cloud AWS module:


Configurable ClientConfiguration

ClientConfiguration, used when initializing AWS clients, can be now defined by creating a bean named "com.amazonaws.ClientConfiguration.BEAN_NAME".

It’s also possible to provide ClientConfiguration for particular integration by defining a bean of type ClientConfiguration and a name specific to the integration - for example, for SQS client, the bean name must be sqsClientConfiguration.

You can read more about client configuration

Speed-up Startup Time

To improve startup times for applications that do not use EC2 instance data, ContextInstanceDataAutoConfiguration is disabled by default. To enable it, set cloud.aws.instance.data.enabled to true.

AWS SDK Version Upgrade

AWS SDK has been upgraded to 1.11.951

Configurable Endpoint for Each Integration

For each integrated AWS service, you can configure Spring Cloud AWS to use a custom endpoint by setting configuration properties. This example shows how to do so:


Using a custom endpoint can be especially useful when you use Localstack in integration tests.

Deprecate XML Configuration

XML Configuration is now deprecated and is going to be removed in the next major version upgrade.

Configurable Region for Each Iintegration

In addition to global region configuration, each integration can have a different region set statically. Read more about configuring regions.

Deprecate @EnableXXX Annotations

@EnableXXX annotations have been deprecated. We recommend using Spring Boot auto-configurations.

Simplify Disabling Integrations

Each service can be now enabled or disabled by setting the enabled property.

Simplify SDK Configuration

DefaultAWSCredentialsProvider and DefaultAWSRegionProviderChain are used now by default. Thecloud.aws.credentials.use-default-aws-credentials-chain and cloud.aws.region.use-default-aws-region-chain properties were dropped.


To simplify project setup for applications that do not use CloudFormation support, CloudFormation-related auto-configurations have been disabled by default. To enable CloudFormation support in Spring Cloud AWS, you must add the following dependency to trigger ContextStackAutoConfiguration:



SES support has been extracted from the context module to separate spring-cloud-aws-ses module. There is also a dedicated starter: spring-cloud-aws-ses-starter.


Spring Cloud AWS comes with basic support for AWS Cognito, simplifying configuring OAuth2. Read more about Cognito support.

Parameter Store

  1. Support loading properties through spring.config.import introduced in Spring Cloud 2020.0. Read more about integrating your Spring Cloud application with the AWS parameter store.
  2. Dropped the dependency to javax.validation:validation-api.

Secrets Manager

  1. Support loading properties through spring.config.import, introduced in Spring Cloud 2020.0 Read more about integrating your Spring Cloud applicationwiththeAWS secrets manager.
  2. Removed the dependency to auto-configure module #526.
  3. Dropped the dependency to javax.validation:validation-api.
  4. Allow Secrets Manager prefix without "/" in the front #736.


  1. The SimpleMessageListenerContainer#isQueueRunning method is now visible to extending classes. #350
  2. Added support for SQS custom data types. #410.
  3. Added support for native SQS messages in SqsListener argument. #295
  4. Added global configuration for message deletion policy. #188
  5. Fixed queue listener graceful shutdown by increasing queue stop time to 20 seconds. queueStopTimeout can be configurable through SimpleMessageListenerContainerFactory. #504 #507
  6. Added support for primitives and no specific data type in SQS message attributes. #221 and #374
  7. Added support for resolving SqsMessageHeaders in SqsListener. Added ApproximateFirstReceiveTimestamp, ApproximateReceiveCount, and SentTimestamp headers #296
  8. SQS listeners, by default, instead of creating custom ObjectMapper instance, use one present in the application context. #533, #522, and #540
  9. Add support for SQS FIFO queues #40


SimpleStorageResource sets content-type property on the S3 object metadata. #262


  1. @NotificationMessageMapping now properly handles special characters. #645
  2. Support String Array SNS messageAttributeDataType. #368


Make RDS instance name configuration more flexible. For example, for an instance named test, instead of setting cloud.aws.rds.test.username=user property, you must now set:




Removed the spring-cloud-aws-actuator module. Instead, we recommend using the dependency to micrometer-registry-cloudwatch directly. #571

Why Has the Package Name Changed?

On the 17th of April, 2020, it was announced that Spring Cloud GCP and Spring Cloud AWS are no longer part of the Spring Cloud release train. Not being a part of the release train also means moving from the Spring Cloud organization on Github and, as an effect, having new Maven coordinates and package names.

We picked awspring as the top level name and io.awspring.cloud as a top level package for Spring Cloud AWS, which leaves us opportunity to create other Spring-related and AWS-related, but not necessarily Spring Cloud-related, packages.

With the great help of Spencer Gibb and other folks from the Spring team, we moved to the new repository and created a new home for Spring Cloud AWS: https://github.com/awspring/spring-cloud-aws.

What's the Future of Spring Cloud AWS?

From now on, our efforts focus on 3.0 - based on AWS SDK 2.0. This release will be an opportunity to revisit every implemented module and align it better with Spring Boot conventions.

2.3.x will receive bug fixes and will be open for community contributions, but we - as the core team - will not focus on adding new features or modules.

2.2.x, being a part of the Hoxton release train, will continue to be maintained in the original Spring Cloud repository.

Who Is Behind Spring Cloud AWS?

Spring Cloud AWS is a community project with Maciej Walkowiak, Eddú Meléndez, and Matej Nedic in the Core Team. We are more than happy to take contributions from the community. In the near future, we are going to update contributing guidelines and publish the roadmap for Spring Cloud 3.0.

Stay tuned.
