java - Java - Quartz CronSchedule 不适用于开始日期和结束日期

Question

当我将 startDate 和 endDate 设置为 Trigger 时，ChronSchedule 只对作业调用一次执行方法。

JobDetail job = JobBuilder.newJob(service)
                    .withIdentity(batchService.getName(), CommonConstants.BATCH_JOB_GROUP).build();
            Trigger trigger = TriggerBuilder
                    .newTrigger()
                    .withIdentity(batchService.getName(), CommonConstants.BATCH_JOB_GROUP)
                    .startAt(startDate)
                    .endAt(endDate)
                    .withSchedule(
                            CronScheduleBuilder.cronSchedule("0/5 * * * * ?"))
                    .build();
            System.out.println("##########" + trigger.getEndTime());
            System.out.println("##########" + trigger.getStartTime());

如您所见，我在触发器上放了一些打印以获取开始日期和结束日期。这似乎是正确的：

##########Fri Oct 20 16:00:00 CEST 2017
##########Fri Oct 20 15:00:00 CEST 2017

在执行方法中，我打印了一个：

public void execute(JobExecutionContext context) throws JobExecutionException
    {   
        System.out.println("Executing job. The next: " + context.getNextFireTime());

    }

但结果令人不安：

Executing job. The next: null

我做错了什么？

我不知道 CronScheduler 或 CronsTrigger，但您可以尝试跟随而不是 CronScheduleBuilder。

导入 org.quartz.* 包。

JobDetail jobDetail = JobBuilder.newJob(MYJOB.class).withIdentity(jobName).withDescription("TryThis").build();

CalendarIntervalTriggerImpl trigger = new CalendarIntervalTriggerImpl("triggername", startTime, endTime,
                                 DateBuilder.IntervalUnit.valueOf("MINUTE"), frequency);

// Try to keep scheduler object as singultant object. 
// OR it'll also work fine if you start scheduler it multiple times with diffrebt scheduler object for JDBCJob store.

SchedulerFactory sf = new StdSchedulerFactory(); 

Scheduler scheduler = sf.getScheduler();  
scheduler.start();

scheduler.scheduleJob(jobDetail, trigger);
