Hibernate Validation is not aware of Spring's MessageSource. You will need to implement a MessageInterpolator. It may look something like below:

public class SpringMessageInterpolator implements MessageInterpolator {

    private final MessageResource messageResource;
    private final MessageInterpolator delegate;

    public SpringMessageInterpolator(MessageResource messageResource, MessageInterpolator delegate) {
        this.messageResource = messageResource;
        this.delegate = delegate;
    }

    @Override
    public String interpolate(String messageTemplate, Context context) {
        Locale locale = Locale.getDefault();
        return interpolate(messageTemplate, context, locale);
    }

    @Override
    public String interpolate(String messageTemplate, Context context, Locale locale) {
        try {
            Object[] args = {};
            return databaseMessageResource.getMessage(messageTemplate, args, locale);
        } catch (NoSuchMessageException ex) {
            return delegate.interpolate(messageTemplate, context, locale);
        }
    }

}
