Answer 1

Are you using Spring 3.1? It is a newly added feature in Spring version 3.1. Please see Validation For @RequestBody Method Arguments

Answer 2

This is an issue in spring 3.0 and it is fixed in 3.1 M2.

https://jira.springsource.org/browse/SPR-6709

If you are using spring 3.0, based on some threads and extensive reading, here is the best approach for this problem. An aspect oriented approach so that we can back out when you upgrade it to the version of spring which fixes this issue.

An aspect which intercepts calls to method which uses @RequestMapping annotation and for each parameter which has @Valid annotation on it, call the corresponding validator in the aspect.
