JSR 303 annotations validation in web tier

[bijukunjummen]

Hi, this is in relation to the issue described in this stackoverflow question - http://stackoverflow.com/questions/36649331/spring-boot-starter-data-rest-notnull-constraint-not-working.

The gist is that the JSR303 annotation don't appear to getting enforced for resources exposed via @RepositoryRestResource. I could see that it does work for JPA based implementations where the check happens prior to data being inserted or updated but for Mongo and other non-JPA stores it would likely ignore the annotations. I wanted to see what the right approach could be here.

I would also love to see a good solution for this.
