Answer from AI

In the Spring Framework, component configuration can be implemented in several ways:

XML configuration — the traditional method where components and their dependencies are described in XML files.

<bean id="myService" class="com.example.MyService" />

Java configuration (annotations @Configuration and @Bean) — configuration through Java classes, allowing the use of type safety and refactoring benefits.

@Configuration
public class AppConfig {
    @Bean
    public MyService myService() {
        return new MyService();
    }
}

Automatic component scanning (@Component, @Service, @Repository, @Controller) — annotating classes for automatic detection and registration in the Spring context.

@Service
public class MyService {
    // ...
}

Using profiles (@Profile) — for defining configurations activated in different environments.

These methods can be combined depending on project requirements.
