I don't use non-POJO parameters usually; but as far as I know
everything that uses databinding does get validated, as long as
annotations are included. Validation works for configuration POJOs as
well as input POJOs.
But you will probably find more information on (Hibernate) bean
validation mailing list, drop wizard user list, or StackOverflow.
And you'd need to include declarations of things you are using I assume.
