org.springframework.beans.factory.support.AutowireCandidateQualifier
Qualifier for resolving autowire candidates. A bean definition that includes one or more such qualifiers enables fine-grained matching against annotations on a field or parameter to be autowired. @author Mark Fisher @author Juergen Hoeller @since 2.5 @see org.springframework.beans.factory.annotation.Qualifier
