/**
* Beans on which the current bean depends. Any beans specified are guaranteed to be
* created by the container before this bean. Used infrequently in cases where a bean
* does not explicitly depend on another through properties or constructor arguments,
* but rather depends on the side effects of another bean's initialization.
* <p>Note: This attribute will not be inherited by child bean definitions,
* hence it needs to be specified per concrete bean definition.
*
* <p>May be used on any class directly or indirectly annotated with
* {@link org.springframework.stereotype.Component} or on methods annotated
* with {@link Bean}.
*
* <p>Using {@link DependsOn} at the class level has no effect unless component-scanning
* is being used. If a {@link DependsOn}-annotated class is declared via XML,
* {@link DependsOn} annotation metadata is ignored, and
* {@literal <bean depends-on="..."/>} is respected instead.
