Java 使用自定义消息验证异常行为

我有一些简单的验证，比如：

@Column(length=6)
@Pattern(regexp = "[0-9]{2}( |-)?[0-9]{3}", message = Errors.kod_pocztowy)
private String kod_pocztowy;

但它会返回奇怪的错误：

[error]     at org.hibernate.validator.internal.engine.ValidatorImpl.validate(ValidatorImpl.java:158)

当我将消息属性更改为文本时，如：

@Column(length=6)
@Pattern(regexp = "[0-9]{2}( |-)?[0-9]{3}", message = "Now its ok")
private String kod_pocztowy;

然后一切似乎都好了。有什么问题吗？有人能给我解释一下吗？

好的，我自己找到的。使用像{}这样的字符会导致Ebean从类中加载消息，并且该消息与该类相关。
