一.导包
<!-- https://mvnrepository.com/artifact/org.quartz-scheduler/quartz -->
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.quartz-scheduler/quartz-jobs -->
<!-- https://mvnrepository.com/artifact/org.quartz-scheduler/quartz-jobs -->
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz-jobs</artifactId>
<version>2.2.1</version>
</dependency>
二.设置我们需要运行的任务(需要继承JOP接口)
package cn.itcast.spider.uitl;
import java.util.Date;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class MyJob implements Job {
/**
* 被定时执行的方法
*/
@Override
public void execute(JobExecutionContext arg0) throws JobExecutionException {
System.out.println(new Date().toString());
}
}
三.设置任务器
public class CrontabSpider {
public static void main(String[] args) throws SchedulerException {
//获取调度工厂
StdSchedulerFactory factory = new StdSchedulerFactory();
//第二步：从调度工厂里面获取到一个可调度的对象
Scheduler scheduler = factory.getScheduler();
//设置任务
JobDetail jobDetail = JobBuilder.newJob(MyJob.class).build();
//设置触发器
Trigger trigger = TriggerBuilder.newTrigger().withSchedule(CronScheduleBuilder.cronSchedule("*/5 * * * * ?")).build(); //调度对象设置时间并设置需要执行的任务第一个是对象,第二个是触发的时间
scheduler.scheduleJob(jobDetail, trigger);
//开始
scheduler.start();
}
}
