Quartz学习

参考网址：http://www.quartz-scheduler.org/documentation/quartz-2.1.x/tutorials/tutorial-lesson-01.html

一个Quartz例子：

public class QuartzTest {
    public static void main(String[] args) {
        try {
            // Grab the Scheduler instance from the Factory
            Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
            // and start it off
            scheduler.start();
            JobDetail job = JobBuilder.newJob(HelloJob.class)
                    .withIdentity("job1", "group1")
                    .build();

            // Trigger the job to run now, and then repeat every 40 seconds
            Trigger trigger = TriggerBuilder.newTrigger()
                    .withIdentity("trigger1", "group1")
                    .startNow()
                    .withSchedule(simpleSchedule()
                            .withIntervalInSeconds(40)
                            .repeatForever())
                    .build();
            // Tell quartz to schedule the job using our trigger
            scheduler.scheduleJob(job, trigger);
            try {
                Thread.sleep(10000);
                scheduler.shutdown();
            }catch (InterruptedException e){
                e.printStackTrace();
            }

        } catch (SchedulerException se) {
            se.printStackTrace();
        }
    }
}

 

一旦一个scheduler被实例化，它就可以启动，等待以及关闭状态。但是scheduler关闭，它不能被重新启动，除非重新实例化。Triggers

• Scheduler - 与scheduler交互的主函数.
• Job - 由scheduler派发的的工作接口.
• JobDetail - 用于定义job实例.
• Trigger - 定义schedule将会触发那个job的组件.
• JobBuilder - 用于定义JobDetail实例.
• TriggerBuilder - 定义触发TriggerBuilder的实例.
