how to do annotation configuration in spring

To configure annotation in Spring, you can follow these steps:

  1. Add the @Configuration annotation to a class to indicate that it will be used for Java-based configuration.

  2. Use the @ComponentScan annotation to specify the base packages to scan for components such as @Component, @Repository, @Service, or @Controller.

  3. If necessary, use the @Import annotation to import additional configuration classes.

  4. Apply specific annotations such as @Bean to methods that will return bean instances.

  5. Optionally, use stereotype annotations like @Component, @Service, @Repository, or @Controller to mark specific classes for auto-detection and automatic bean registration.

  6. Use other annotations like @Value, @Autowired, and @Qualifier to wire beans and inject properties.

These steps will help you configure annotation in Spring for your application.
