Hibernate驗證程序：@NotEmpty不適用於空值

我已使用@NotEmpty標記註釋了字符串字段。Hibernate驗證程序：@NotEmpty不適用於空值

當我試圖堅持與此字段的值「」的實體，它工作正常。機制檢測到驗證錯誤並引發一個InvalidStateException異常來通知問題。

但是，當我試圖堅持與該字段的值爲null的實體時，會引發UndeclaredThrowableException（由InvocationTargetException引起，由PropertyValueException引起：not-null屬性引用null或瞬態值）異常，因爲系統正在嘗試點擊數據庫在不可爲空的字段上具有空值。

問題很明顯：爲什麼驗證機制不能檢測到這種情況？我認爲它應該引發一個InvalidStateException異常，而不是一個UndeclaredThrowableException。

我用的是以下庫：

- hibernate-annotations 3.3.1.GA 
    - hibernate-validator 3.0.0.ga 
    - hibernate-core 3.2.6ga

，現在我剛剛升級到

- hibernate-annotations 3.4.0.GA 
    - hibernate-validator 3.1.0.GA 
    - hibernate-core 3.3.2

這些都是最新的穩定版本。

但它仍然無法正常工作。

有什麼想法？

試圖合併事件監聽器註冊了一個SessionFactory的bean：

<property name="eventListeners"> 
    <map> 
    <entry key="merge"> 
     <bean class="org.hibernate.validator.event.ValidateEventListener"/> 
    </entry> 
    </map>

'@ NotEmpty'不保證財產不爲空;這裏一定有其他的東西。你能發佈整個堆棧跟蹤嗎？ – ChssPly76 2009-10-26 20:03:00

我已經添加了錯誤跟蹤到問身體。當屬性取值「」時，它可以正常工作，但是當它取值爲空時，它不起作用。注意我在保存前進行合併。 – Alberthoven 2009-10-26 20:19:19

首先，「合併之前保存」沒有任何意義。適當時，您可以使用merge（）而不是save（），但merge（）已經返回一個持久實例 - 以下save（）是毫無意義的。其次，默認情況下，merge（）不會默認調用pre-insert/pre-update事件監聽器;從而驗證永遠不會執行。合併之前，您可以通過合併事件manually specifying listener或manually invoking validatior解決此問題。

但空值（「」）的價值它的作品！我的意思是，驗證程序檢測到驗證失敗，即使在保存前調用合併。 – Alberthoven 2009-10-26 20:46:11

用空字符串merge（）成功保存實體（空字符串不爲空 - 所以沒有Nullability異常）。以下save（）調用由於@NotEmpty而失敗的驗證器;整個交易將被回滾。 – ChssPly76 2009-10-26 20:49:29

如何在合併之前強制驗證？ ValidateEventListener數組中沒有合併事件 – Alberthoven 2009-10-26 20:54:04

我得到了它本身固定，一旦我做了以下同樣的錯誤：

public class CustomEventListener implements PreUpdateEventListener{...}

而不是早期的代碼是：

public class CustomEventListener{..}
