springboot实现定时任务-Schedule

1.引入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
</dependency>

2.在启动类上添加@EnableScheduling注解

3.创建定时任务

@Component
public class ScheduleTest {

    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    @Scheduled(cron = "0/2 * * * * *")
    public void print(){
        System.out.println("定时任务执行："+sdf.format(new Date()));
    }
}

4.启动项目，这个打印就会两秒执行一次
