You can create an application listener, it's designed specifically for such needs. In this case it will be executed every time context is started (or refreshed).

@Component
public class DatabaseFillerOnStartup implements ApplicationListener<ContextRefreshedEvent> {
    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        ...
    }
}
