To use these features in an application, you can build it as a Spring Boot application that depends on spring-cloud-config-client (for an example, see the test cases for the config-client or the sample application). It can be set for a specific DataBinder instance and implement validation without annotations (non-declarative approach). Using Spring Boot 2.4.1: Add the @Validated annotation to the class.
