定时任务(quartz)
在线Cron表达式生成器:https://cron.qqe2.com
添加依赖
springboot中包含直接用
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-quartz</artifactId>
</dependency>
就需要2步
1、创建一个定时任务类
@Component
public class MyJob {
@Scheduled(cron = "0/2 * * * * ?")
public void timerJob(){
System.out.println("1-------1111");
}
}
2、在启动类添加注解@EnableScheduling
@SpringBootApplication
@EnableScheduling
public class QuartzDemoApplication {
public static void main(String[] args) {
SpringApplication.run(QuartzDemoApplication.class, args);
}
}
