Spring In the case of code redundancy, package scanning is performed in the spring container...

org.springframework.context.annotation.ClassPathScanningCandidateComponentProvider In spring5.3.x, there is code redundancy. During package scanning, when parsing class meta information, when creating a ScannedGenericBeanDefinition object, its constructor has set the source attribute. But after creating it, set it up again。It's still the same in the latest version
