Trigger

【使用案例2】：
        [创建job类,使用CronSchedulerBuilder]:
            import org.quartz.Job;
            import org.quartz.JobExecutionContext;
            import org.quartz.JobExecutionException;

            public class SecondJob implements Job{

                public void execute(JobExecutionContext context) throws JobExecutionException {
                    System.out.println("使用crontrigger....");
                }

            }


        [创建测试类]：
            import org.quartz.CronScheduleBuilder;
            import org.quartz.JobBuilder;
            import org.quartz.JobDetail;
            import org.quartz.Scheduler;
            import org.quartz.Trigger;
            import org.quartz.TriggerBuilder;
            import org.quartz.impl.StdSchedulerFactory;

            import job.SecondJob;

            public class SecondScheduler {
                public static void main(String[] args) throws Exception {
                    //创建一个定时器对象
                    Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
                    
                    //创建一个jobDetail对象
                    JobDetail jobDetail = JobBuilder.newJob(SecondJob.class).withIdentity("job_2", "group_2").build();
                    
                    //创建一trigger
                    Trigger trigger = TriggerBuilder.newTrigger().withIdentity("trigger_2", "group_2")
                            .startNow().withSchedule(CronScheduleBuilder.cronSchedule("0 17 1 * * ?")).build();
                    
                    scheduler.scheduleJob(jobDetail,trigger);
                    scheduler.start();
                }
            }
