        public static Registry spring​(org.springframework.beans.factory.ListableBeanFactory beanFactory)
        Creates a registry backed by the given bean factory.

        Note: Spring ListableBeanFactory API doesn't current support looking up beans with parameterized types. The adapted Registry instance doesn't support this because of this limitation. There is a feature request to add the generics functionality to the Spring ListableBeanFactory API.

        Parameters:
        beanFactory - the bean factory to back the registry
        Returns:
        a registry that retrieves objects from the given bean factory
