org.springframework.context.annotation.ClassPathBeanDefinitionScanner
A bean definition scanner that detects bean candidates on the classpath, registering corresponding bean definitions with a given registry ( {@code BeanFactory}or {@code ApplicationContext}).
Candidate classes are detected through configurable type filters. The default filters include classes that are annotated with Spring's {@link org.springframework.stereotype.Component @Component}, {@link org.springframework.stereotype.Repository @Repository}, {@link org.springframework.stereotype.Service @Service}, or {@link org.springframework.stereotype.Controller @Controller} stereotype.
Also supports Java EE 6's {@link javax.annotation.ManagedBean} andJSR-330's {@link javax.inject.Named} annotations, if available. @author Mark Fisher @author Juergen Hoeller @author Chris Beams @since 2.5 @see AnnotationConfigApplicationContext#scan @see org.springframework.stereotype.Component @see org.springframework.stereotype.Repository @see org.springframework.stereotype.Service @see org.springframework.stereotype.Controller
