SpringBoot has @Scheduled annotation for scheduling tasks. But it only works with fixed rates. In this tutorial I tried to show how to create our own scheduler for dynamic scheduling.

This repository created for my blog post on same topic: http://mbcoder.com/dynamic-task-scheduling-with-spring/

This service shows how to use Spring's own scheduler with a fixed rate or cron expression.

This service shows how to create our own scheduler and make it work with dynamic rates. In this service we can see how to use a value from database as our next execution time. We can also see using different approaches within the same scheduler such as using fixed values, dynamic values, cron expression etc.

Same as dynamic scheduler but on top of that we can now cancel and re-activate the scheduler on demand.

In this service we see how to create a scheduler to schedule a job to be executed at an exact date instead of giving a rate.

This is advanced version of cancellable scheduler and it is more like a production ready version. With this we can now easily add or remove jobs from other classes. As an example, SchedulingController shows how adding and removing job works from outside.

All the above classes are to demonstrate different possibilities of custom schedulers. You can combine those functionalities in your own scheduler according to your needs. If you have any question, or if you want to achieve something that is not done here yet, leave a comment in above blog post and I will try to help as soon as I can.
