Quartz调用大全

Quartz调用大全

 

1.Quartz应用范围广泛，可单独执行也可在spring中嵌入执行。

   类似的定时任务在linux下可以用crontab执行

 

 

2.实现代码：

QuartzTest :主要执行类

 

package com.taobao.terminator.allen.QuartzTest;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.quartz.CronTrigger;import org.quartz.JobDetail;import org.quartz.JobListener;import org.quartz.Scheduler;import org.quartz.SchedulerFactory;import org.quartz.impl.StdSchedulerFactory;public class QuartzTest {private final static Log logger = LogFactory.getLog(QuartzTest.class);public static void main(String[] args) {System.out.println("this is test for Quartz");//初始化scheduler工厂类SchedulerFactory factory = new StdSchedulerFactory();try {//DirectSchedulerFactory生成一个实例，可create一个带名字的shcedulerScheduler shceduler = factory.getScheduler();//Quartz监听器，分为全局和局部的。局部的需要在特定的jobDetail中重回一次，全局不需要JobListener jobListener = new QuartzListener("quartz - test");shceduler.addJobListener(jobListener);//Shceduler的Context类似于servlet的context，功能相似.Context会传递给监听器shceduler.getContext().put("coreName", "coreName");//同样可以保存context的key-value ,jobDetail.getJobDataMap()JobDetail jobDetail = new JobDetail("Full-Detail", "Full-Detail-Group", QuartzJob.class);jobDetail.addJobListener("quartz - test");jobDetail.getJobDataMap().put("jobDetail-data", "jobDetail");//生成触发器CronTrigger trigger = new CronTrigger("Full-Trigger" , "Full-Trigger-Group");trigger.setCronExpression("0/30 * * * * ?");//添加jobshceduler.scheduleJob(jobDetail, trigger);//开始执行shcedulershceduler.start();while(true) {Thread.sleep(1000 * 10);System.out.println("触发定时任务");shceduler.triggerJob("Full-Detail", "Full-Detail-Group");Thread.sleep(1000 * 40);//终止正在运行的jobshceduler.interrupt("Full-Detail", "Full-Detail-Group");System.out.println("the schedule is over");//关闭定时器shceduler.shutdown();break;}} catch (Exception e) {logger.error("生成调试器失败" , e);}}} 

 

 

QuartzListener :监听器，可设置在jobDetail ,trigger, scheduler三个层次

                          主要对job执行之前及之后的进行操作，context可负责通信及异常，类似于servlet的context功能

package com.taobao.terminator.allen.QuartzTest;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;import org.quartz.JobListener;public class QuartzListener implements JobListener{private String listenerName = "quartz-listener";public QuartzListener(String listenerName) {this.listenerName = listenerName;}public String getName() {return this.listenerName;}public void jobToBeExecuted(JobExecutionContext context) {System.out.println("the job listener is start");}public void jobExecutionVetoed(JobExecutionContext context) {}public void jobWasExecuted(JobExecutionContext context,JobExecutionException jobException) {System.out.println("the job listener is end");}} 

 

 

QuartzJob:注意中断方法的实现，可用于停止当前job，也可用shcedule.deleteJob(name,groupName)进行直接删除

import org.quartz.InterruptableJob;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;import org.quartz.UnableToInterruptJobException;public class QuartzJob implements InterruptableJob{private boolean stop = false ;public void execute(JobExecutionContext context) throws JobExecutionException {if(!this.stop) {System.out.println("this is ok");}}public void interrupt() throws UnableToInterruptJobException {this.stop = true ;System.out.println("it is over");}public boolean isStop() {return stop;}}
