QuartzJob 類：創建job類，實現org.quartz.job接口類，並實現execute方法。

package com.pgw.quartz;
import java.util.Date;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class QuartzJob implements Job {
    @Override
    public void execute(JobExecutionContext arg0) throws JobExecutionException {
    System.out.println("hello world !!!!"+new Date());
    }
      
}

QuartzCronTrigger 類：創建crontrigger類，繼承CronTrigger類，實現 Serializable接口

package com.pgw.quartz;
import java.io.Serializable;
import org.quartz.CronTrigger;
public class QuartzCronTrigger extends CronTrigger implements Serializable {
    /**
     *
     */
    private static final long serialVersionUID = -9078011008686279425L;
    public QuartzCronTrigger(){
             
    }
    public void setCronExpress(String corn,String name,String groupName){
    try {
        this.setCroncorn);
         this.setName(name);
        this.setGroup(groupName);
                 
    }
    catch (Exception e) {
        e.printStackTrace();
    }
             
    }
             
}

QuartzMain 類

1、如果Scheduler沒有設置名稱，通過scheduler = factory.getDefaultScheduler();獲取的Scheduler對象名稱爲DefaultQuartzScheduler。

2、Quartz可以設置一個Scheduler，然後在這個Scheduler下配置多對trigger和job度對象。

package com.pgw.quartz;
import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.impl.StdSchedulerFactory;
public class QuartzMain{
    public static void main(String[] args) {
       // 創建一個jobDetail對象，將Job實際業務類放入jobDetail中
       JobDetail jobDetail = new JobDetail("demo", "demo", QuartzJob.class);
       // 創建一個觸發器
       CronTrigger triggers = new CronTrigger("demo", "demo");
       //CronTrigger ctrigger = new CronTrigger("smSendTaskSduling", "smSendTaskSduling");
       try {
         // 設置觸發器 名字
        // triggers.setName("demo");
         // 設置觸發器所屬組
         //triggers.setGroup("demo");
         // 設置觸發時間cron表達式
         triggers.setCronExpression("0 * 13 * * ?");
         // 將jobDetail放入觸發器中
        // triggers.setJobGroup("demo");
         // 創建schedulerFactory對象
         StdSchedulerFactory factory = new StdSchedulerFactory();
         Scheduler scheduler = factory.getDefaultScheduler();
           // Register the JobDetail and Trigger
         scheduler.scheduleJob(jobDetail, triggers);
           // 掛起定時線程
         scheduler.start();
       }catch(Exception ex){
          ex.printStackTrace();
       }
    }
}
