我目前正在将应用程序的一部分移植到scala，它使用Oval库.问题的方法是Validator.validate方法.它具有两个

I am currently porting part of an application to scala and it uses the Oval library. The method is question is the Validator.validate method. It has two signatures:

List<ConstraintViolation> validate(Object validatedObject)
List<ConstraintViolation> validate(Object validatedObject, String... profiles) 

scala代码通常如下所示:

The scala code looks generally like this:

def validate(toValidate: AnyRef) = {
  val validator = createValidator
  validator.validate(toValidate)
}

错误消息:

error: ambiguous reference to overloaded definition,
[INFO] both method validate in class Validator of type (x$1: Any,x$2: <repeated...>[java.lang.String])java.util.List[net.sf.oval.ConstraintViolation]
[INFO] and  method validate in class Validator of type (x$1: Any)java.util.List[net.sf.oval.ConstraintViolation]
[INFO] match argument types (AnyRef)
[INFO]       this.validator.validate(toValidate)

我如何才能做到这一点?

How can I get this be be unambiguous?

推荐答案

我认为这可能与基本上，这是一个已知的java-scala-interop问题，唯一的解决方法是使额外的Java适配器在Scala中可访问.

Basically, it is a known java-scala-interop problem, and the only workarounds involve extra Java adapters to make accessible in Scala.
