/**
* Indicates one or more resources containing bean definitions to import.
*
* <p>Like {@link Import @Import}, this annotation provides functionality similar to the
* {@literal <import/>} element in Spring XML. It is typically used when
* designing {@link Configuration @Configuration} classes to be bootstrapped by
* {@link AnnotationConfigApplicationContext}, but where some XML functionality such as
* namespaces is still necessary.
*
* <p>By default, arguments to the {@link #value()} attribute will be processed using
* an {@link XmlBeanDefinitionReader}, i.e. it is assumed that resources are Spring
* {@literal <beans/>} XML files. Optionally, the {@link #reader()} attribute may be
* supplied, allowing the user to specify a different {@link BeanDefinitionReader}
* implementation, such as
* {@link org.springframework.beans.factory.support.PropertiesBeanDefinitionReader}.
