Overview

@ConfigurationProperties is a Spring Boot annotation that, once placed on a bean, specifies that the properties of that bean ban be injected from properties present in the Spring environment.

@Component
@ConfigurationProperties(prefix = "playground.spring.pi")
public class ... {
}

The 'prefix' attribute defines the namespace for the configuration properties exposed by the component.
