SimpleJob的使用实例

quartz使用的是1.8.6版本

import java.util.Date;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class SimpleJob implements Job {

	@Override
	public void execute(JobExecutionContext jobCtx)
			throws JobExecutionException {
		System.out.println(jobCtx.getTrigger().getName() +  " triggered.time.is:" + (new Date()));
	}

}

[code]
import java.util.Date;

import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.SimpleTrigger;
import org.quartz.impl.StdSchedulerFactory;

public class SimpleTriggerRunner {
public static void main(String[] args) {
try {
//创建一个JobDdtail实例，指定SimpleJob，组名为jgroup1，名称为job1_1
JobDetail jobDetail = new JobDetail("job1_1", "jgroup1", SimpleJob.class);

//通过SimpleTrigger定义调度规则：马上启动，每2秒运行一次，共运行100次
SimpleTrigger simpleTrigger = new SimpleTrigger("trigger1_1", "tgroup1");
simpleTrigger.setStartTime(new Date()); //开始时间
simpleTrigger.setRepeatInterval(2000); //运行频率
simpleTrigger.setRepeatCount(10); //运行次数

//通过SchedulerFactory获取一个调度器实例
SchedulerFactory schedulerFactory = new StdSchedulerFactory();
Scheduler scheduler = schedulerFactory.getScheduler();

//注册并进行调度
scheduler.scheduleJob(jobDetail, simpleTrigger);
//调度开始
scheduler.start();
} catch (SchedulerException e) {
e.printStackTrace();
}
}
}
[/code]
运行结果：
trigger1_1 triggered.time.is:Wed Apr 17 10:39:10 CST 2013
trigger1_1 triggered.time.is:Wed Apr 17 10:39:11 CST 2013
trigger1_1 triggered.time.is:Wed Apr 17 10:39:13 CST 2013
trigger1_1 triggered.time.is:Wed Apr 17 10:39:15 CST 2013
trigger1_1 triggered.time.is:Wed Apr 17 10:39:17 CST 2013
trigger1_1 triggered.time.is:Wed Apr 17 10:39:19 CST 2013
trigger1_1 triggered.time.is:Wed Apr 17 10:39:21 CST 2013
trigger1_1 triggered.time.is:Wed Apr 17 10:39:23 CST 2013
trigger1_1 triggered.time.is:Wed Apr 17 10:39:25 CST 2013
trigger1_1 triggered.time.is:Wed Apr 17 10:39:27 CST 2013
trigger1_1 triggered.time.is:Wed Apr 17 10:39:29 CST 2013
每次执行都是n+1条

其中注册代码也可以写成
[code]
simpleTrigger.setJobGroup("jgroup1"); //1.指定关联的Job组名
simpleTrigger.setJobName("job1_1"); //1.指定关联的Job名称
scheduler.addJob(jobDetail, true); //2.注册JobDetail
scheduler.scheduleJob(simpleTrigger); //3.注册指定了关联jobDetail的Trigger
[/code]
1.2.3的顺序不能随意变动
