java - 带有表情语言的椭圆形

Question

我正在使用 Oval http://oval.sourceforge.net/对于 java bean 验证，我在使用表达式语言功能时遇到异常。

我的代码如下所示:

@NotNull(errorCode = "paymentCard.number.invalid", message = "Required", when = "_this.cardType != null")
private String cardNumber;

结果是

WARNING: Cannot determine constraint when formula based on annotation $Proxy10
java.lang.ArrayIndexOutOfBoundsException: 1

INFO: Available ScriptEngine language names: [[js, rhino, JavaScript, javascript, ECMAScript, ecmascript]]

我不知道为什么会发生这种情况，有人可以帮助我吗？

提前致谢

您需要在公式前加上语言 ID 前缀，例如

when="js:_this.cardType != null"
