title: Spring ScheduledTask - start/stop support?
body: <p>Is there a way to start or stop a task scheduled using Spring Scheduled Tasks initialized using context file or @Scheduled annotation?</p>
  
  <p>I would like to start the task when required and stop it when the task is no longer needed to be run.</p>
  
  <p>If this is not possible, any alternative to injecting spring variables to a thread?</p>
