定时执行程序-Quartz简单实例

定时执行程序-Quartz简单实例

1、加jar包：Quartz自己quartz-1.8.3.jar和依赖包commons-logging.jar 、slf4j-log4j12-1.5.10.jar 、slf4j-api-1.5.10.jar

2、一个类搞定！！！，直接run

import org.quartz.CronTrigger;

import org.quartz.Job;

import org.quartz.JobDetail;

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

import org.quartz.Scheduler;

import org.quartz.SchedulerFactory;

import org.quartz.impl.StdSchedulerFactory;

import java.util.Date;

public class QuartzReport implements Job{

public void execute(JobExecutionContext cntxt) throws JobExecutionException {

System.out.println( "输出："+cntxt.getJobDetail().getJobDataMap().get("name")+new Date());

}

public static void main(String[] args) {

try {

SchedulerFactory schedFact=new StdSchedulerFactory();

Scheduler sched=schedFact.getScheduler();

sched.start();

JobDetail jobDetail=new JobDetail("a","b",QuartzReport.class);

jobDetail.getJobDataMap().put("name","lucy");

CronTrigger trigger=new CronTrigger("c","d");

trigger.setCronExpression("0/1 * * * * ? " ); // 启动之后立即执行 每一秒继续重复。

sched.scheduleJob(jobDetail, trigger);

} catch (Exception e) {

e.printStackTrace();

}

}

}

/**
