Answer 1

A better way to do this is to define the scheduling in xml using the task name space

If you for some reason want to do it with annotation, you need to create an annotation that has another optional attribute where you can specify the property name or better still a property placeholder expression or Spel expression.

@MyScheduled(fixedDelayString="${delay}")
