简单触发器测试：
package job;
import java.util.concurrent.TimeUnit;

import org.quartz.Scheduler;

import org.quartz.SimpleScheduleBuilder;

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.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：

#线程池优先级
org.quartz.threadPool.threadPriority = 5

###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
