How to cancel Spring timer execution

Question

I need to cancel Spring timer execution or at least change the execution frequency based on some conditions. Was using both org.springframework.scheduling.quartz.Simpl

Answer 1

The solution is to assign an id to the org.springframework.scheduling.timer.TimerFactoryBean and then retrieve this bean from the application, cast it to Timer and call cancel method on that object.

Answer 2

This is by far not the best solution but if you can't come up with anything else you could always use a boolean that would be checked each time the event is fired and if the boolean is false the run method of the timertask should immediately terminate.

Answer 3

NOTE: This is for Spring 3.0+

1. Read Spring documentation on scheduling tasks

2. Use a TaskScheduler service, such as a TimerManagerTaskScheduler or ThreadPoolTaskScheduler.

3. Schedule your task by calling some TaskScheduler.schedule*() method and store the returning ScheduledFuture.

4. When you want to cancel execution, invoke ScheduledFuture.cancel(). That will stop further invocations of your task. At this time, you can reschedule if you want by calling TaskScheduler.schedule*() for your task with different parameters.
