Quartz使用例子

1.这个例子使用的是
quartz-all-2.1.7.jar,
log4j-1.2.16.jar,
slf4j-api-1.6.1.jar,
slf4j-log4j12-1.6.1.jar

2.上代码

package com.demo;
import org.quartz.*;
import org.quartz.impl.StdSchedulerFactory;
public class TestQuartz {
	public static void main(String[] args) throws SchedulerException {
        SchedulerFactory schedulerFactory = new StdSchedulerFactory();
        Scheduler scheduler = schedulerFactory.getScheduler();
 
        JobDetail jobDetail = JobBuilder.newJob()
                .ofType(HelloJob.class)
                .usingJobData("Test1","Quartz")
                .withIdentity("Test1","Group1")
                .build();//通过JobBuilder构建JobDetailImpl 实例,也可以直接new JobDetailImpl
 
        Trigger trigger = TriggerBuilder.newTrigger()
                .withSchedule(CronScheduleBuilder.cronSchedule("0/3 * * * * ?"))
                .forJob("Test1","Group1")       //Trigger找到对应的名称为Test1组为Group1的Job,如果不存在则会在执行scheduler.scheduleJob(jobDetail,trigger);报错
                .build();//通过TriggerBuilder构建CronTriggerImpl实例,也可以直接new CronTriggerImpl
 
        scheduler.scheduleJob(jobDetail,trigger);//任务每3秒触发一次
 
        scheduler.start();
    }
}

package com.demo;

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

public class HelloJob implements Job {

	public void execute(JobExecutionContext context) throws JobExecutionException {
		JobDataMap jobDataMap = context.getJobDetail().getJobDataMap();
        String a = (String)jobDataMap.get("Test1");
        System.out.println("Hello " + a);
	}

}

任务的定义比较简单,只需要implements Job,实现execute方法即可,触发任务时,execute方法会执行.

示例定义的是一个每三秒执行一次的任务,通过TriggerBuilder构建Trigger实例,也可以直接通过new方式构建.

这个示例使用的是默认的quartz配置,如果指定配置,可以编辑一个Properties文件

schedulerFactory.initialize(props);//初始化指定配置<span></span>
