Configuring auto-discovery for spring beans is quite easy and straight forward in the spring application. With auto-discovery in place, you won’t have to manually register the beans in spring config files. This is a way to minimize the xml verbosity in your application. You just need to add the following line to the spring config file and it’s done.

the above line make spring scan through the edu.jft.prashant.utils package and will register the classes as beans that are annotated with:

  • @Component
  • @Controller
  • @Repository
  • @Service
  • Any custom annotation that is itself annotated with @Component.

So, let’s modify the SimplePoem in this example for auto-discovery. Annotate it with @Component like:

With our class marked with @Component, component-scan will scan the package and will register it as a bean in the spring context.
