將Hibernate 3.2.5遷移到3.6

目前我們在將應用程序從Hibernate 3.2.5遷移到3.6.1時遇到了很多問題。將Hibernate 3.2.5遷移到3.6

，我們所面臨的第一個錯誤是：

重度：無效的列名稱btn_name「。雖然btn_name沒有映射到哪裏。實際的映射是btnName。

這裏是我的映射文件

關注com.sampleproject.client.beansdm.metadata.uicontrols.InputControl連接子類的映射有一個名爲btnName場。它的3.2.5版本正常工作，但當我將其更改爲較新的休眠版本時，它會停止響應。

是否有任何可能的jar衝突？

請幫忙。

感謝你，的問候，從3.5遷移到3.6時

的Hibernate Version Comparison指南指出：

然而，對於仍在使用的hbm.xml 用戶，你應該知道，我們選擇了使用 org.hibernate.cfg.EJB3NamingStrategy 在AnnotationConfigration使用舊 org.hibernate.cfg.DefaultNamingStrategy H的替代在配置上使用。這可能會導致命名不匹配; 一個已知的地方，這是一個問題是如果你依靠的命名策略，默認情況下，協會 （許多一對多和元素的集合）表的名稱。如果你發現自己在這種情況下，你可以告訴休眠通過調用配置＃setNamingStrategy和傳遞 org.hibernate.cfg.DefaultNamingStrategy＃INSTANCE
使用傳統 org.hibernate.cfg.DefaultNamingStrategy

NamingStrategy接口定義了幾個方法，如String foreignKeyColumnName(String propertyName, String propertyEntityName, String propertyTableName, String referencedColumnName)用於確定由EJB3NamingStrategy實現的列和關聯的名稱。我建議你在EJB3NamingStrategy類中看看這些方法的實現，看看它是如何將屬性名稱轉換爲列名稱的。

它看起來像hibernate現在將下劃線添加到它希望列名通過一個這些轉換在數據庫中，並且當它無法在您的數據庫中找到結果列名'btn_name'時感到不安。

尼斯答案...我可以創建自己的EJB3NamingStrategy通過擴展它，重寫方法和提供的地方來了解hibernate。 – 2011-03-12 07:36:14

什麼應該是我的最後一步？我有近190張桌子，幾乎不可能將HBM轉換爲所有人的註釋。我很感謝你的時間和努力，謝謝你。 – 2011-03-12 07:55:35

您不必從hbm更改爲註釋以使用不同的NamingStrategy。請參閱http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html/session-configuration。html＃configuration-namingstrategy瞭解如何實現新的NamingStrategy的詳細信息。你甚至可以擴展EJB3NamingStrategy，只是改變導致悲傷的命名。我還會在你的配置文件中打開show_sql選項，這樣你就可以看到hibernate使用什麼命令來訪問你的db。 – 2011-03-16 13:23:39
