Cron Expression Generator for Java

// Using cron expression
BackgroundJob.scheduleRecurrently("my-job", "0 9 * * *",
    () -> myService.doWork());

// Or use the Cron helper class
BackgroundJob.scheduleRecurrently("my-job", Cron.daily(9, 0),
    () -> myService.doWork());

@Scheduled(cron = "0 0 9 * * *")
public void scheduledTask() {
    myService.doWork();
}

// Note: Spring uses 6 fields (includes seconds)

CronTrigger trigger = TriggerBuilder.newTrigger()
    .withIdentity("myTrigger")
    .withSchedule(CronScheduleBuilder.cronSchedule("0 0 9 * * ?"))
    .build();

// Note: Quartz uses 6-7 fields and ? for day fields
