I want to create my own Annatotation Constraint, because I hava a String which contains a list of emails seperated by a comma.

I follow the doc from here : http://docs.jboss.org/hibernate/validat ... aints.html

In my project I use Hibernate Validator as Provider for Bean validation. And I notice that Hibernate provide an @Email constraint.

Is it possible to call the org.hibernate.validator.constraints.impl.EmailValidator::isValid from my own Validator class ?

I made the following and its work:

public class EmailsValidator implements ConstraintValidator<Emails, String> {

private EmailValidator emailValidator = new EmailValidator();

public void initialize(Emails constraintAnnotation) {

public boolean isValid(String value, ConstraintValidatorContext context) {
    if (value == null || value.isEmpty()) {
        return true;
    final String[] emails = value.split(",\\s*");
    for (String anEmail : emails) {
        System.out.println("anEmail = " + anEmail);
        if (!emailValidator.isValid(anEmail, context)) {
            return false;
    return true;

Is it the most efficient way to make it ?
