Manually call Hibernate URL validator in spring-boot

Question

I am using spring-boot 1.4.0 and hibernate-validator 5.2.0. I have a model which contains custom validator inside the custom validator i want to check whether the property value is a valid URL for that i need to call URLValidator in hibernate but no luck.Could anyone please guide me to resolve this issue

CustomValidator.java

@Component
public class BookValidator extends GenericValidator<Book,    ConstraintValidatorContext> implements ConstraintValidator<ValidBooks,  List<Book>> {


public BookValidator() {
    addValidators();
}

private void addValidators() {
 getValidators().add((book, context) -> {
        boolean isValid = book.getUrl(); //here i want to check against Hibernate URL validator 
        if (!isValid) {
            context.disableDefaultConstraintViolation();
            context
                    .buildConstraintViolationWithTemplate("Book URL should be valid!")
                    .addConstraintViolation();
        }
        return isValid;
    });
}
@Override
public void initialize(ValidBooks constraintAnnotation) {
}
}

How can i check whether the URL is a valid one boolean isValid = book.getUrl(); using hibernate URLValidator?

This works:

AnnotationDescriptor<URL> descriptor = new AnnotationDescriptor<URL>( URL.class ); 
URL url = AnnotationFactory.create(descriptor);
URLValidator urlValidator = new URLValidator();
urlValidator.initialize(url);

boolean isValid = urlValidator.isValid(book.getUrl(), context);
