022 * Strategy interface to be implemented by objects than can resolve bean name
023 * information, given a newly instantiated bean object. Invocations to the
024 * {@link #resolveWiringInfo} method on this interface will be driven by
025 * the AspectJ pointcut in the relevant concrete aspect.

027 * <p>Metadata resolution strategy can be pluggable. A good default is
028 * {@link ClassNameBeanWiringInfoResolver}, which uses the fully-qualified
029 * class name as bean name.
