035 * {@link EnableAutoConfiguration Auto-configuration} for Spring Data's Mongo Reactive
036 * Repositories.
037 * <p>
038 * Activates when there is no bean of type
039 * {@link org.springframework.data.mongodb.repository.support.ReactiveMongoRepositoryFactoryBean}
040 * configured in the context, the Spring Data Mongo {@link ReactiveMongoRepository} type
041 * is on the classpath, the ReactiveStreams Mongo client driver API is on the classpath,
042 * and there is no other configured {@link ReactiveMongoRepository}.
043 * <p>
044 * Once in effect, the auto-configuration is the equivalent of enabling Mongo repositories
045 * using the {@link EnableReactiveMongoRepositories} annotation.
