Job监听器：

package job;

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

import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.Trigger;
import org.quartz.TriggerKey;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class SchedEventLister implements Runnable{

	private Scheduler sched = null;

	public SchedEventLister(TriggerKey triggerKey,Scheduler sched) {
		log.info("触发器线程监听启动....");
		this.triggerKey = triggerKey;
		this.sched = sched;
	}

	@Override
	public void run() {

		log.info("触发器线程监听中。。。。"
				+ new SimpleDateFormat("yyyy-MM-dd hh:mm:ss")
						.format(new Date()));

		// 获取当前触发器的状态
		Trigger.TriggerState ts = null;
		try {
			ts = sched.getTriggerState(triggerKey);
		} catch (SchedulerException e) {
			e.printStackTrace();
		}

		// 如果为暂停状态就恢复
		if (ts == Trigger.TriggerState.PAUSED) {

			// 暂停10秒在恢复
			try {
				log.warn("暂停当前线程5秒钟后在恢复触发器...,触发器组名: " + triggerKey.getGroup()
						+ ",触发器名称: " + triggerKey.getName());
				Thread.sleep(5L * 1000L);
			} catch (InterruptedException e1) {
				e1.printStackTrace();
			}

			// 恢复触发器
			log.warn("正在恢复了触发器...,触发器组名: " + triggerKey.getGroup()
					+ ",触发器名称: " + triggerKey.getName());
			try {
				sched.resumeTrigger(triggerKey);
			} catch (SchedulerException e) {
				throw new RuntimeException(e);
			}

		} else if (ts == Trigger.TriggerState.NORMAL) {
			log.info("触发器线程监听中。。。。,状态：正常 ");
		} else if (ts == Trigger.TriggerState.NONE) {
			log.info("触发器线程监听中。。。。,状态：没有触发器 ");
		} else if (ts == Trigger.TriggerState.ERROR) {
			log.info("触发器线程监听中。。。。,状态：错误 ");
		} else if (ts == Trigger.TriggerState.BLOCKED) {
			log.info("触发器线程监听中。。。。,状态：堵塞 ");
		}
	}
}

简单触发器测试：

package job;

import java.util.concurrent.TimeUnit;

import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SimpleScheduleBuilder;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdSchedulerFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class testSimpleTrriger {
	private static Logger logger = LoggerFactory.getLogger(testSimpleTrriger.class);

	public static void main(String[] args) {

		try {
			// 获取Scheduler实例
			Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
			// 具体任务
			JobDetail job = JobBuilder.newJob(SimpleJob.class).withIdentity("SimpleJob", "Job-Group-Simple").build();
			// 触发时间点
			SimpleScheduleBuilder simpleScheduleBuilder = SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(5).repeatForever();
			Trigger trigger = TriggerBuilder.newTrigger().withIdentity("SimpleTrigger", "Trriger-Group-Simple").
					startNow().withSchedule(simpleScheduleBuilder).build();
			// 交由Scheduler安排触发
			scheduler.scheduleJob(job, trigger);
			scheduler.start();
			try {
				TimeUnit.MINUTES.sleep(2);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
			// 关闭Scheduler
			scheduler.shutdown();
		} catch (SchedulerException se) {
			logger.error(se.getMessage(), se);
		}
	}

}

CronTrigger触发器测试：

package job;

import java.util.concurrent.TimeUnit;

import org.quartz.CronScheduleBuilder;
import org.quartz.CronTrigger;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdSchedulerFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class TestCronTrriger {
	private static Logger logger = LoggerFactory.getLogger(testSimpleTrriger.class);

	public static void main(String[] args) {

		try {
			// 获取Scheduler实例
			SchedulerFactory schedulerFactory = new StdSchedulerFactory();
	        Scheduler cronScheduler = schedulerFactory.getScheduler();
			// 具体任务
			JobDetail job = JobBuilder.newJob(SimpleJob.class).withIdentity("SimpleJob", "Job-Group-Simple").build();
			// 触发时间点
			// 交由Scheduler安排触发
		    String cronExpression = "0/5 * * * * ?"; // 每分钟的30s起，每5s触发任务  
		    CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule(cronExpression);
		    CronTrigger cronTrigger = TriggerBuilder.newTrigger().withIdentity("SimpleTrigger", "Trriger-Group-Simple")  
	        	       .withSchedule(cronScheduleBuilder)  
	        	       .build();
	        cronScheduler.scheduleJob(job, cronTrigger);
	        cronScheduler.start();
			try {
				/* 为观察程序运行，此设置主程序睡眠2分钟才继续往下运行（因下一个步骤是“关闭Scheduler”） */
				TimeUnit.MINUTES.sleep(2);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
			// 关闭Scheduler
			cronScheduler.shutdown();
		} catch (SchedulerException se) {
			logger.error(se.getMessage(), se);
		}
	}
}

上面两个测试类只是测试触发器种类不同而已，使劲处理的job是相同的

quartz.properties文件：
#线程池实现类
org.quartz.threadPool.class =org.quartz.simpl.SimpleThreadPool
#线程池数
org.quartz.threadPool.threadCount = 5
#线程池优先级
org.quartz.threadPool.threadPriority = 5
#线程池运行模式守后，还是前台
org.quartz.threadPool.makeThreadsDaemons=false
###线程池配置的继承属性
org.quartz.threadPool.threadsInheritGroupOfInitializingThread=true
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread=true
###保存job调度执行信息到RAM，这种方式当应用下次重启时，job调度信息容易丢失
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore
org.quartz.jobStore.misfireThreshold = 60000
############.JobStoreTX，是将job调度信息保存到RDB中，应用重启时可以重新调度job
#org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
#org.quartz.jobStore.dataSource=test
#org.quartz.dataSource.test.driver=com.mysql.jdbc.Driver
