@SpringBootApplication
@EnableJpaRepositories
public class StudentsTableApplication implements CommandLineRunner {
    private Logger logger = LoggerFactory.getLogger(this.getClass());
    public static void main(String[] args) {
        SpringApplication.run(StudentsTableApplication.class, args);
    }
    @Autowired
    private StudentRepository studentRepository;
    @Override
    public void run(String... args) throws Exception {

    }
}
