org.springframework.context.annotation.ClassPathScanningCandidateComponentProvider
A component provider that scans the classpath from a base package. It then applies exclude and include filters to the resulting classes to find candidates.
This implementation is based on Spring's {@link org.springframework.core.type.classreading.MetadataReader MetadataReader}facility, backed by an ASM {@link org.springframework.asm.ClassReader ClassReader}. @author Mark Fisher @author Juergen Hoeller @author Ramnivas Laddad @author Chris Beams @since 2.5 @see org.springframework.core.type.classreading.MetadataReaderFactory @see org.springframework.core.type.AnnotationMetadata @see ScannedGenericBeanDefinition
