验证@ScriptAssert可以访问静态方法

Question

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静态方法外部化,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.

Answer 1

具有静态方法的类的类名必须是完全限定的。

ScriptAssert(script="com.example.demo.ComplexValidation.isComplexSubValid(_this.attributeA,_this.attributeB)",
          lang = "javascript")

公共静态布尔 isComplexSubValid(对象 a, 对象 b)...
