一开仰、構(gòu)建maven項目

1丧裁、在pom.xml中引入jar包

 <!--引入quartz依賴-->
        <!-- https://mvnrepository.com/artifact/org.quartz-scheduler/quartz -->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.3.0</version>
        </dependency>
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>
            <version>2.3.0</version>
        </dependency>
        <!--引入quartz依賴 END-->

二讼撒、創(chuàng)建兩個類

1再菊、QuartzTest01.class

public class QuartzTest01 {

    public static void main(String[] args) throws SchedulerException {
        // 創(chuàng)建JobDetail作業(yè)信息
        JobDetail jobDetail = JobBuilder.newJob(MyJob.class)
                .withDescription("this is a test job")
                .withIdentity("testJob","testGroup")
                .build();

        // 向任務(wù)傳遞數(shù)據(jù)
        JobDataMap jobDataMap = jobDetail.getJobDataMap();
        jobDataMap.put("uname","張三");
        jobDataMap.put("uage",16);

        //任務(wù)運行的時間，SimpleSchedle 類型觸發(fā)器有效
        long time = System.currentTimeMillis() + 3 * 1000L; // 三秒后啟動任務(wù)
        Date startTime = new Date(time);

        // 創(chuàng)建Trigger宏邮，使用SimpleScheduleBuilder 或者 CronScheduleBuilder
        Trigger trigger = TriggerBuilder.newTrigger()
                .withDescription("")
                .withIdentity("ramTrigger", "ramTriggerGroup")
                .startAt(startTime)  //默認當(dāng)前時間啟動
                //普通計時器
                .withSchedule(SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(3).withRepeatCount(3))//間隔3秒训裆，重復(fù)3次
                //表達式計時器
                //.withSchedule(CronScheduleBuilder.cronSchedule("0/3 * * * * ?")) //3秒執(zhí)行一次
                .build();

        // 創(chuàng)建Scheduler工廠
        SchedulerFactory schedulerFactory = new StdSchedulerFactory();

        // 從工廠中獲取調(diào)度器實例
        Scheduler scheduler = schedulerFactory.getScheduler();

        //注冊任務(wù)和定時器

        scheduler.scheduleJob(jobDetail,trigger);

        //啟動 調(diào)度器
        scheduler.start();
    }
}

2.MyJob.class

public class MyJob implements Job {
    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        Date date = new Date();
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

        System.out.println("定時器任務(wù)執(zhí)行:" + simpleDateFormat.format(date));
        JobDataMap map=jobExecutionContext.getMergedJobDataMap();
        System.out.println("參數(shù)值"+map.get("uname"));
        System.out.println("參數(shù)值"+map.get("uage"));
    }
}
