QuartzJob 类：创建job类，实现org.quartz.job接口类，并实现execute方法。
1 2 3 4 5 6 7 8 9 10 11 | 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{ public void execute(JobExecutionContext arg0) throws JobExecutionException { System.out.println("Hello world !!!" + new Date()); } } |
QuartzCronTrigger 类：创建crontrigger类，继承CronTrigger类，实现 Serializable接口
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | package com.pgw.quartz; import org.quartz.CronTrigger; import java.io.Serializable; import java.text.ParseException; public class QuartzCronTrigger extends CronTrigger implements Serializable { private static final long serialVersionUID = 1L; public QuartzCronTrigger() { } public void setCronExpress(String corn, String name, String groupName) { try { this.setCronExpression(corn); this.setName(name); this.setGroup(groupName); } catch (ParseException e) { e.printStackTrace(); } } } |
QuartzMain 类
1、如果Scheduler没有设置名称，通过scheduler = factory.getDefaultScheduler();获取的Scheduler对象名称为DefaultQuartzScheduler。
2、Quartz可以设置一个Scheduler，然后在这个Scheduler下配置多对trigger和job度对象。
