// Trigger That Executes Every Wednesday at 3:00PM
Trigger trigger = TriggerUtils.MakeWeeklyTrigger(TriggerUtils.WEDNESDAY, 15, 0);
trigger.setName("trigger1");
trigger.setGroup("group1");
If you would like a Trigger that executes every week on a specified day of the week at a specified time, use CronTrigger:
// CronTrigger That Executes Every Wednesday at 3:00PM
Trigger trigger = new CronTrigger("trigger1", "group1");
trigger.setCronExpression("0 0 15 ? * WED");
If you don’t care what time it runs (only the period is important), you can use SimpleTrigger (note that startTime will be the time when the trigger was instantiated):
// SimpleTrigger That Executes Every 7 Days
Trigger trigger = new SimpleTrigger("trigger1", "group1");
// 7(days per week) * 24(hours per day) * 60(minutes per hour) * 60(seconds per minute) * 1000(milliseconds per second)
trigger.setRepeatInterval(7L * 24L * 60L * 60L * 1000L);
Technically, if you want to specify the time the trigger will fire, you can use a SimpleTrigger, but it’s a lot of work to get the startTime right:
// SimpleTrigger That Executes Every Wednesday at 3:00PM
java.util.Calendar startTime = java.util.Calendar.getInstance();
startTime.set(java.util.Calendar.HOUR_OF_DAY, 15);
startTime.set(java.util.Calendar.MINUTE, 0);
startTime.set(java.util.Calendar.SECOND, 0);
startTime.set(java.util.Calendar.MILLISECOND, 0);
startTime.set(java.util.Calendar.DAY_OF_WEEK, java.util.Calendar.WEDNESDAY);
//if the startTime will be before the current time, move to next week
if (startTime.getTime.before(new Date()) {
startTime.add(java.util.Calendar.DAY_OF_MONTH, 7);
}
Trigger trigger = new SimpleTrigger("trigger1", "group1");
trigger.setRepeatCount(SimpleTrigger.REPEAT_INDEFINITELY);
trigger.setStartTime(startTime.getTime());
//7(days per week) * 24(hours per day) * 60(minutes per hour) * 60(seconds per minute) * 1000(milliseconds per second)
trigger.setRepeatInterval(7L * 24L * 60L * 60L * 1000L);
You may also simply use a DateIntervalTrigger to
/*
* Note that this will create a trigger that starts immediately.
* To control the start time, use trigger.setStartTime(Date)
*/
DateIntervalTrigger trigger = new DateIntervalTrigger("trigger1", "group1", DateIntervalTrigger.IntervalUnit.WEEK, 1);
