Dynamic Task Scheduling with Spring

Summary Spring makes it very easy to schedule a job to run periodically. All we need to do is to put @Scheduled annotation above the method and provide the necessary parameters such as fixedRate or cron expression. But when it comes to change this fixedRate on the fly, @Scheduled annotation is not enough. Ultimately, what I wanted to do was periodically load my configuration table from a database. But the fixedRate which indicates how frequently I will load this table is also stored in the very same database.
