import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;

@SpringBootApplication
@EnableConfigurationProperties(AppBootConfig.class)
public class SampleApplication implements CommandLineRunner {

	@Autowired
	private AppBootConfig appBootConfig;
	
	public static void main(String[] args) throws Exception {
		SpringApplication.run(SampleApplication.class, args);
	}
	@Override
	public void run(String... args) throws Exception {
		System.out.println(appBootConfig.getName());
