springboot 定时器使用

第一步：在Application中加入@EnableScheduling注解

@SpringBootApplication

@EnableScheduling

public class RabbitmqApplication {

    public static void main(String[] args) {

        SpringApplication.run(RabbitmqApplication.class, args);

    }

}

第二步：创建定时的类， 加入注解@Component

@Component

public class TaskTest {

    @Scheduled(cron ="*/5 * * * * ?")

    public void test() {

        System.out.println("aaaaaaaaaaaaaa");

    }

}
