Answer 1

This is what worked for me. I had to used the @Inject tag.

    public class FooValidator implements ConstraintValidator {
        private ValidationService validationService;
        @Inject
        public FooValidator(ValidationService validationService){
            this.validationService = validationService;
        }
        @Override
        public void initialize(final FooValid constraintAnnotation) {
            // TODO Auto-generated method stub
        }
        @Override
        public boolean isValid(final Integer value, final ConstraintValidatorContext context) {
            // this.validationService is always NULL!
            Assert.notNull(this.validationService, "the validationService must not be null");
            return false;
        }

}
