<context:componentscan> how does it work?

Can "context: componentscan" scan custom annotations? If so, where does it store the scanned beans in application context after scanning? How can I access the results?

We register beans or components in XML configuration file. So Spring can detect those beans, components. Spring also support to auto scan, detect and instantiate beans from pre-defined project package via the annotation. So we don't have to declare in the configuration anymore. For example:

<context:component-scan base-package="abc.controller, abc.service" />

in your Controller or Service, you just have to add annotation like:

@Controller
public class SampleController

@Service
public class SampleService

Spring will know that your SampleController and SamplerService and you can use it as you want.
