S3CrtAsyncClientAutoConfiguration enabled by default when using only Parameter Store

[svincio]

Type: Bug

Component: Parameter Store/S3

Describe the bug
When importing the library io.awspring.cloud:spring-cloud-aws-starter-parameter-store:3.2.0 in my project, it automatically imports the dependency io.awspring.cloud:spring-cloud-aws-autoconfigure:3.2.0. The latter contains the class io.awspring.cloud.autoconfigure.s3.S3CrtAsyncClientAutoConfiguration which has its enabling parameter set to true by default.

This causes unwanted S3 functionality to be automatically activated in applications that only want to use io.awspring.cloud specifically for Parameter Store functionality while using S3 with a different library. The auto-configuration attempts to configure S3 settings that aren't needed and can generate errors in this scenario.

For other purposes in my project, I also need to import:

• software.amazon.awssdk:s3-transfer-manager
• software.amazon.awssdk.crt:aws-crt:0.21.7

This further contributes to the problem by activating the unwanted S3 CRT configuration.

Expected Behavior

The S3CrtAsyncClientAutoConfiguration should only be activated when the library io.awspring.cloud:spring-cloud-aws-starter-s3 is explicitly imported, not when only using the Parameter Store module.

Proposed Solution

Modify the auto-configuration logic of S3CrtAsyncClientAutoConfiguration so that it is activated only when:

1. The dependency io.awspring.cloud:spring-cloud-aws-starter-s3 is present, or
2. It is explicitly enabled through a configuration property

Environment

• Spring Boot: 3.3.5
• spring-cloud-aws-starter-parameter-store: 3.2.0
• Java: 21

Temporary Workaround

Currently, it's possible to manually disable this configuration by adding the following property:

spring.cloud.aws.s3.enabled=false
