Spring: Internals of @ComponentScan

The @ComponentScan annotation in Spring, located within the org.springframework.context.annotation package, helps automatically detect beans in a Spring application. It can identify classes annotated with stereotypes like @Configuration, @Component, @Service, @Controller, and @Repository. The annotation can be used with or without parameters, such as basePackageClasses() or basePackages(), to specify scanning packages. It essentially replaces the XML tag <context:component-scan/> and includes various attributes for customizing the component scanning process, like nameGenerator, scopeResolver, scopedProxy, useDefaultFilters, includeFilters, and excludeFilters.
