springBoot回调函数

springBoot的回调函数在springBoot的项目启动之后会立即调用此回调函数，回调函数有两种：

第一种：

@SpringBootApplication
public class DataApplication implements ApplicationRunner {
Logger logger= LoggerFactory.getLogger(DataApplication.class);
	 public static void main(String[] args) {
        SpringApplication.run(DataApplication.class,args);
    }
    //程序加载完之后启动回调函数
    @Override
    public void run(ApplicationArguments args) throws Exception {
        logger.info("回调函数")
    }
}

第二种：

@SpringBootApplication
public class DataApplication implements CommandLineRunner {
Logger logger= LoggerFactory.getLogger(DataApplication.class);
	 public static void main(String[] args) {
        SpringApplication.run(DataApplication.class,args);
    }
    @Override
    public void run(String... args) throws ParseException {
    	logger.info("回调函数")
    }
}
