Converting explicit into implicit configuration in Spring

@Configuration
public class AppConfig {

    @Bean
    public AppService appService() {
        return new AppServiceImpl(appRepository());
    }

    @Bean
    public AppRepository appRepository() {
        ...
    }
}

@Configuration
@ComponentScan("com.services")
public class AppConfig {
}

@Component
public class AppServiceImpl implements AppService {
    @Autowired
    public AppServiceImpl(AppRepository appRepository) {
        this.appRepository = appRepository;
    }
}
