我的Spring + hibernate应用程序有点问题。我的应用程序似乎无法找到我的persistance.xml，我已经基本上尝试了每个位置来实现它。似乎没有任何工作。因为我刚接触spring，hibernate，jpa ......然后它实际上可能是一个我无法弄清楚的错误。 这是我的hibernateContext.xml，它使用JPA。

答案 0 :(得分：1)

首先，您应该将其称为persistence.xml而不是persistance.xml。

现在添加您的文件applicationContext.xml：

<property name="persistenceUnitName" value="YourPersistanceUnitName" />
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence/persistence.xml"/>

作为具有正确的persitence单位名称的entityManagerFactory的属性。这应该正常工作
