JSR 303實現給出ClassCastException

我正在使用JSR 303實現自定義驗證註釋，並且出現了以下錯誤。我在Cross field validation with Hibernate Validator (JSR 303)JSR 303實現給出ClassCastException

java.lang.ClassCastException: com.sun.proxy.$Proxy95 cannot be cast to com.my.validator.FieldMatch

有人可以幫我嗎？

報告的類似問題請您分享您的約束條件註釋和約束條件驗證器的定義嗎？約束註釋可能引用另一個註釋類型的驗證器。 – Gunnar

我有不同的問題相同的異常。由於錯誤，我有兩個不同的路徑MyCustomValidator – Hamedz

如果您已經編寫了自定義驗證註釋，請確保@Constraint（validatedBy = FieldMatchValidator.class）具有正確的驗證程序類。如果validatedBy具有不同的類，那麼您將得到ClassCastException。請參閱How to solve cast issue java.lang.ClassCastException: $Proxy cannot be cast to NotEmpty wich is annotation

@Target({TYPE, ANNOTATION_TYPE}) 
@Retention(RUNTIME) 
@Constraint(validatedBy = FieldMatchValidator.class) 
@Documented 
public @interface FieldMatch 
{ 
}
