quartz maven下载jar

<!-- quartz begin --><dependency>  <groupId>org.quartz-scheduler</groupId>  <artifactId>quartz</artifactId>  <version>2.2.3</version>  </dependency>  <dependency>  <groupId>org.quartz-scheduler</groupId>  <artifactId>quartz-jobs</artifactId>  <version>2.2.3</version>  </dependency><!-- quartz end -->

quartz jar包下载地址响应超慢的

直接上代码

一：执行任务类

import java.text.SimpleDateFormat;import java.util.Date;import org.quartz.Job;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;public class QuartzJob implements Job {@Overridepublic void execute(JobExecutionContext arg0) throws JobExecutionException {SimpleDateFormat sd = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");System.out.println("开始时间:"+sd.format(new Date()));//逻辑处理写这里System.out.println("逻辑处理...........");}}

二：创建触发器，调度器

import java.text.SimpleDateFormat;import java.util.Date;import org.quartz.CronScheduleBuilder;import org.quartz.CronTrigger;import org.quartz.JobBuilder;import org.quartz.JobDetail;import org.quartz.Scheduler;import org.quartz.SchedulerFactory;import org.quartz.TriggerBuilder;import org.quartz.impl.StdSchedulerFactory;public class ExecuteQuartz {public void run(){try {// 首先，必需要取得一个Scheduler的引用SchedulerFactory sFactory = new StdSchedulerFactory();Scheduler sched = sFactory.getScheduler();//创建定时调度的任务JobDetail job = JobBuilder.newJob(Quartz.class).withIdentity("Job", "JobGroup").build();//创建定时调度任务多少时间执行一次(这里使用corn表达式,现在是10秒一次)CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity("Trigger", "JobGroup")

.withSchedule(CronScheduleBuilder.cronSchedule("0/10 * * * * ?")).build();//开始计时。Date date = sched.scheduleJob(job, trigger);//启动定时任务sched.start();} catch (Exception e) {e.printStackTrace();}}public static void main(String[] arg){ExecuteQuartz a = new ExecuteQuartz();a.run();}}

直接运行，在控制台查看效果。是不是很简单呢？

有后续~~
