Spring MVC Annotations Date Range Validation

 

What is the better way to to implement date range validation for the following use case:

  • Date should be before or after specified date;
  • The Time difference in comparison with current time (now) is greater/less then some period of time. (As example check whether User is more than 21 years old).

    • The one way to implement this is to put this functionality inside validators. And in every controller write this logic for myself.

    In order to have better re-use it's possible to create custom annotation. Looking into Existing annotations especially:

  • @Past
  • @Future

    • These annotations are not reusable at all. They've designed for single condition and for me it's a question why it's designed in such way.

    I tend to implement these use cases with creation of new custom annotation. Can anybody suggest better approach or provide some argument against Spring custom annotations?
