How can automatic bean creation be configured in Spring?

In Spring, automatic bean creation can be configured using annotations and component scanning.

Main steps:

1. Annotate classes that should become beans with annotations such as @Component, @Service, @Repository, or @Controller.
2. Enable package scanning in Spring configuration using @ComponentScan.

Example:

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

@Component
public class MyService {
    // service logic
}

When Spring starts, it will automatically find the MyService class and create its bean, which can be injected using @Autowired.

This avoids manual bean definitions in XML or Java configuration and simplifies dependency management.
