验证@ScriptAssert可以访问静态方法

JSR303 Bean Validation实现Hibernate-Validator（4.1.0）提供了org.hibernate.validator.constraints.ScriptAssert注释 .

我得到了它来调用非静态方法 .

@ScriptAssert(script="_this.isComplexSubValid(_this.attributeA,_this.attributeB)",
              lang = "javascript")

...
public boolean isComplexSubValid(Object a, Object b)...

但现在我想将 isComplexSubValid 外部化为静态方法，以便在不同的类中重用它 . 但是我没有使用javascript验证器进行静态调用 .

@ScriptAssert(script="ComplexValidation.isComplexSubValid(_this.attributeA,_this.attributeB)",
              lang = "javascript")

public static boolean isComplexSubValid(Object a, Object b)...

抛出：

所以我的问题是如何在脚本标签中调用静态方法？

请不要告诉我，我可以实现我的验证器，而不是使用@Script标签 .
