public @interface SpringBootConfiguration

Indicates that a class provides Spring Boot application @Configuration. Can be used as an alternative to the Spring's standard @Configuration annotation so that configuration can be found automatically (for example in tests).

Application should only ever include one @SpringBootConfiguration and most idiomatic Spring Boot applications will inherit it from @SpringBootApplication.
