Quartz 基本编码

导入依赖

    <!--核心包-->
    <dependency>
      <groupId>org.quartz-scheduler</groupId>
      <artifactId>quartz</artifactId>
      <version>2.3.0</version>
    </dependency>

写一个类实现Job接口

public class HelloJob implements Job{
    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        //获得JobDetail对象
        JobDetail jobDetail = context.getJobDetail();
        JobKey key = jobDetail.getKey();
        //获取标识
        System.out.println(key.getName());
        System.out.println(key.getGroup());
        System.out.println("当前时间:"+new Date());
    }
}

写一个启动类

public class QuartzTest  {
    public static void main(String[] args) throws SchedulerException {
        //创建一个scheduler调度器
        Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
        //创建一个Trigger触发器
        Trigger  trigger = TriggerBuilder.newTrigger()
　　　　　　　　　　//标识
                .withIdentity("trigger1","group1")
                //每3秒中触发一次,一直触发 repeatForever
                //withRepeatCount 执行几次
                .withSchedule(SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(3).repeatForever())
                .build()
                ;
        //创建一个jobDetail
        JobDetail job = JobBuilder.newJob(HelloJob.class).withIdentity("job1","group1").build();
        //将jobDetail 和 触发器 增加到调度器中
        scheduler.scheduleJob(job,trigger);
        //启动,调度器开启工作
        scheduler.start();
    }
}
