Spring Framework became JSR303 compliant from version 3 onward I think.

http://docs.spring.io/spring/docs/current/spring-framework-reference/html/validation.html#validation-beanvalidation

Spring Framework 4.0 supports Bean Validation 1.0 (JSR-303) and Bean Validation 1.1 (JSR-349) in terms of setup support, also adapting it to Spring’s Validator interface.
