027/**
028 * Indicates that a class provides Spring Boot application
029 * {@link Configuration @Configuration}. Can be used as an alternative to the Spring's
030 * standard {@code @Configuration} annotation so that configuration can be found
031 * automatically (for example in tests).
032 * <p>
033 * Application should only ever include <em>one</em> {@code @SpringBootConfiguration} and
034 * most idiomatic Spring Boot applications will inherit it from
035 * {@code @SpringBootApplication}.
