使用自定義休眠類型時ehcache錯誤？

我體驗了我目前使用hibernate 3.6.2-final和ehcache 2.6.2分析的錯誤。使用自定義休眠類型時ehcache錯誤？

我最近開始使用自定義類型來處理數據庫中存儲爲「OUI」/「NON」的值，作爲java中的布爾值。

我正在使用org.hibernate.type.YesNoType的改編。這部分工作。

當我打開的Ehcache上，我得到一個高速緩存命中以下錯誤：在對象上進行設置字符串值企圖被處理，因爲屬性是一個boolean值，失敗......

在我的日誌中，我有：在類中的IllegalArgumentException：fr.senat.base_senateurs.libsen.hbm.Dpt，setter方法的屬性：evetempub 預期類型：java.lang.Boolean，實際值：java.lang.String

兩個有趣的例外是：

你有一個想法（除了停止使用二級緩存:-)）？

好的，所以，實際上，我的自定義類型很好的假設並不是那麼真實。我知道這是冬眠的YesNo類型的複製粘貼，所以我很有信心... 但事實並非如此。

問題是它的組裝和拆卸方法不一致。

在拆機，值（此處爲布爾型）是由下面的片段轉化成字符串：

@Override 
public Serializable disassemble(Object value) { 
    return (value == null) ? null : value.toString(); 
}

但是在組裝時，該字符串左「原樣」由下面的代碼片斷：

@Override 
public Object assemble(Serializable cached, Object owner) { 
    return (cached == null) ? null : cached; 
}

正確的實現是：

@Override 
public Object assemble(Serializable cached, Object owner) { 
    if(cached == null) { 
     return null; 
    } 
    if(cached.equals("true")) { 
     return true; 
    } 
    return false; 
}

由於組裝/拆卸我直到在緩存中執行了一些序列化之前，thod對才被使用，直到利用二級緩存的應用程序使用它時才檢測到該錯誤。

在從數據庫中的「常規」對象負載，AstractEntityPersister＃水合物是由loadFromResultSet（org.hibernate.loader.Loader的線1527）稱爲水合物通過調用nullSafeGet的類型

在執行自定義類型的對話緩存命中，緩存項由org.hibernate.cache.entry.StructuredCacheEntry＃destructure「拆分」，然後由assembleCacheEntry進行彙編。在某些時候，它會調用自定義類型「assemble」方法。

請注意，爲了提高效率，我會盡量避免字符串比較，但您會明白... :-)
