/**
* Indicates whether a bean is to be lazily initialized.
*
* <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>If this annotation is not present on a Component or Bean definition, eager
* initialization will occur. If present and set to {@literal true}, the
* Bean/Component will not be initialized until referenced by another bean or
* explicitly retrieved from the enclosing
* {@link org.springframework.beans.factory.BeanFactory}. If present and set to
* {@literal false}, the bean will be instantiated on startup by bean factories
* that perform eager initialization of singletons.
*
* <p>If Lazy is present on a {@link Configuration} class, this indicates that all
* {@link Bean} methods within that {@literal Configuration} should be lazily
* initialized. If Lazy is present and false on a Bean method within a
* Lazy-annotated Configuration class, this indicates overriding the 'default
* lazy' behavior and that the bean should be eagerly initialized.
