CommandLineRunner is a simple Spring Boot interface with a run method. Spring Boot will automatically call the run method of all beans implementing this interface after the application context has been loaded.Jul 23, 2565 BE

@SpringBootApplication
public class SpringBootConsoleApplication 
  implements CommandLineRunner {

    private static Logger LOG = LoggerFactory
      .getLogger(SpringBootConsoleApplication.class);

    public static void main(String[] args) {
        LOG.info("STARTING THE APPLICATION");
        SpringApplication.run(SpringBootConsoleApplication.class, args);
        LOG.info("APPLICATION FINISHED");
    }
 
    @Override
    public void run(String... args) {
        LOG.info("EXECUTING : command line runner");
 
        for (int i = 0; i < args.length; ++i) {
            LOG.info("args[{}]: {}", i, args[i]);
        }
    }
}
