Manually call Spring Annotation Validation

Question

I\'m doing a lot of our validation with Hibernate and Spring Annotations like so:

public class Account {
    @NotEmpty(groups = {Step1.class, Step2.class})

Adding to answered by @digitaljoel, you can throw the ConstraintViolationException once you got the set of violations.

Validator validator = Validation.buildDefaultValidatorFactory().getValidator();
        Set> violations = validator.validate( notionalProviderPaymentDTO );

        if(!violations.isEmpty()) {
            throw new ConstraintViolationException(violations);
        }

You can create your own exception mapper which will handle ConstraintViolationException and send the errors messages to the client.
