Hibernate持久

Question

我得到這個錯誤：

GRAVE: Could not configure datastore from file

hibernate.cgf.xml：

任何解決方案？

Answer 1

該配置看起來不正確。您正在定義2個事務工廠（可能還有其他錯誤）。

<property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property> 
<property name="hibernate.transaction.factory_class">net.sf.hibernate.transaction.JDBCTransactionFactory</property> 

我建議你到谷歌的配置文件的例子，並閱讀文檔。
