How are Bean components created and managed within the Spring Framework?

In the Spring Framework, Bean components are created and managed by the IoC (Inversion of Control) container. The main steps are:

1. Bean Definition — a class is annotated with annotations (@Component, @Service, @Repository) or described in XML configuration files.
2. Scanning and Registration — Spring scans specified packages and registers found Beans in the context.
3. Instance Creation — the container creates Bean objects, managing their lifecycle.
4. Dependency Injection — Spring automatically injects necessary dependencies via constructors, setters, or fields annotated with @Autowired.
5. Lifecycle Management — the container calls initialization and destruction methods if they are defined.

Example:

@Component
public class MyService {
    @Autowired
    private MyRepository repository;

    public void doWork() {
        repository.saveData();
    }
}

In configuration:

@Configuration
@ComponentScan(basePackages = "com.example")
public class AppConfig {
}

Thus, Spring takes care of creating, wiring, and managing Bean objects, simplifying development and increasing application modularity.
