Component scanning is an effective mechanism in Spring that automatically detects and registers beans in the application context, avoiding the need for XML definitions.
The @ComponentScan annotation allows you to specify base packages for Spring to scan, streamlining the detection of classes that should be treated as beans.
By using component scanning, developers can reduce boilerplate code significantly and enhance maintainability, aligning with the convention over configuration principle.
Customization options available with component scanning include specifying multiple base packages and utilizing filters to precisely include or exclude certain classes.
