URL validator for JEE6 Beans Validation 1.0

Question

How can I create a custom validator for a URL field in Beans Validation 1.0. But how can I pass the URL string passed via JSON into my constraint validator?

@ValidURL
private URL myUrl;

---

public class URLValidator implements ConstraintValidator<ValidURL, CharSequence> {...}

---

@Target({METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER})
@Retention(RUNTIME)
@Constraint(validatedBy = {URLValidator.class})
@Constraint(validatedBy = {})
public @interface ValidURL {

    String message() default "must be a valid URL";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

I know the latest Hibernate Validator has a @URL validation but I cannot move to the latest version.

Edit: With the above I am hitting the following. So my question is how does Hibernate convert the URL type to the CharSequence used by the ConstraintValidator?

javax.validation.UnexpectedTypeException: HV000030: No validator could be found for type: java.net.URL.

Doh，刚意识到Hibernate验证程序@URL是针对String类型的，而不是java.net.URL
