本文介绍如何在SpringBoot项目中配置定时任务，并详细列出项目POM文件中各种依赖的使用，包括Spring Boot Starter、MyBatis、Swagger等。

1.搭建一个Springboot项目，这个就先忽略了哈

2.POM文件

        </plugins>
    </build>
</project>

3.添加注解

在程序主入口添加注解@EnableScheduling
在这里插入图片描述
新建一个class文件，定义一个方法，在方法上添加@Scheduled注解，cron属性可以自定义cron表达式，我的配置在了yml文件中


    @Scheduled(cron = "${cron.rk}")
    public  void test(){
        System.out.println("=====================定时任务开启========================");
    }

cron表达式定义在了application.yml文件中

#定时时间
cron:
  #测试每隔十秒执行一次定时任务
  test: 0/10 * * * * ?
  #每一小时入库一次视频数据
  rk: 0 0 0/1 * * ?
  #请求每十秒执行一次
  req: 0/10 * * * * ?

最后启动项目验证定时任务
