我的第一个Quartz代码

创建Maven项目

打开Eclipse->File->Project->Maven ->Maven Project直接下一步输入Group Id和Artifact Id ，点击[Finish]按钮

Maven Repository搜索quartz关键字并选择最新的quartz版本

选择2.3.0版本复制quartz依赖到刚创建的maven项目的pom.xml文件中

<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.3.0</version>
</dependency>

创建一个HelloJob 类集成Job接口，并实现void execute方法

import java.text.SimpleDateFormat;
import java.util.Date;

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

public class HelloJob implements Job {

	public void execute(JobExecutionContext arg0) throws JobExecutionException {
		//打印当前的执行时间
		Date date = new Date();
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		System.out.println("Current time is:"+sdf.format(date));
		//编写具体的业务逻辑 
		System.out.println("hello world");
		
	}

}

创建一个HelloScheduler,并且调用Scheduler方法

import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.quartz.SimpleScheduleBuilder;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdSchedulerFactory;

public class HelloScheduler {

    public static void main(String[] args) throws Exception {
        //创建一个JobDetail实例，将该实例与HelloJob class绑定
        JobDetail jobDetail = JobBuilder.newJob(HelloJob.class).withIdentity("myJob","group1").build();
        //创建一个Trigger实例，定义该Job立即执行，并且每隔2秒钟重复执行一次，直到永远
        Trigger trigger = TriggerBuilder.newTrigger().withIdentity("myTrigger", "group1").startNow().withSchedule(SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(2).repeatForever()).build();
        //创建Scheduler实例
        SchedulerFactory sfact = new StdSchedulerFactory();
        Scheduler scheduler = sfact.getScheduler();
        scheduler.start();
        scheduler.scheduleJob(jobDetail, trigger);
    }
    
}

运行结果如下：
