…liasFor When use of the deprecated feature is detected, a WARNING log message will be generated analogous to the following. WARN o.s.c.a.AnnotationBeanNameGenerator - Support for convention-based stereotype names is deprecated and will be removed in a future version of the framework. Please annotate the 'value' attribute in @org.springframework.context.annotation.AnnotationBeanNameGeneratorTests$ConventionBasedComponent1 with @AliasFor(annotation=Component.class) to declare an explicit alias for @component's 'value' attribute. See gh-31089 Closes gh-31093

Overview
Although #20615 introduced the use of
@AliasForfor@Component(value)in stereotype annotations (@Service,@Controller,@Repository,@Configuration,@RestController), the framework does not actually rely on@AliasForsupport when looking up a component name via stereotype annotations. Rather, the framework has custom annotation parsing logic inAnnotationBeanNameGenerator#determineBeanNameFromAnnotation()which effectively ignores explicit annotation attribute overrides configured via@AliasFor.Thus, although we can introduce the use of
@AliasForin@ControllerAdviceand@RestControllerAdviceto create aliases for@Component(value)(see #21108), those aliases will not be honored unless we revise the algorithm inAnnotationBeanNameGenerator.Related Issues
