[Spring boot] CommandLineRunner and Autowired

Previously we use Application Context to get Bean and Dependenies injection. It is actually easier to use 'CommonLineRunner'.

Main beneift is we can use @Autowired.

 

@SpringBootApplication
public class SpringAopApplication implements CommandLineRunner{
private Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private Business1 business1;
@Autowired
private Business2 business2;
public static void main(String[] args) {
SpringApplication.run(SpringAopApplication.class, args);
}
@Override
public void run(String... args) throws Exception {
logger.info(business1.calculateSomething());
logger.info(business2.calculateSomething());
}
}
