@EnableScheduling//开启定时任务
@EnableTransactionManagement//开启事务
@MapperScan("com.my.learn.mapper")
@SpringBootApplication
@EnableAspectJAutoProxy //开启spring对注解aop的支持
public class MyBatisLearnApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyBatisLearnApplication.class);
    }
}
//@PropertySource("classpath:/xxxx.properties") 可以读取指定文件
@Component
public class FixedPrintTask {
    @Scheduled(cron = "${task.rule}")
    public void execute() {
        System.out.println("schedule execute " + System.currentTimeMillis());
    }
    @Scheduled(cron = "0/5 * * * * ?")
    public void execute2() {
        System.out.println("schedule execute 2 " + System.currentTimeMillis());
    }
}
