java - hibernate : "ClassNotFoundException: javax.persistence.spi.ProviderUtil"

Question

我的应用程序正在尝试使用 Hibernate 注释。我已经安装了 3.5.0 版的 Hibernate，但是当我尝试加载我的应用程序时，出现以下异常:

显然，我遗漏了一些东西，或者我有不兼容的 jars 再次，但对于我来说，我无法弄清楚问题出在哪里。我有 hibernate3.jar、ejb3-persistence.jar 和 Hibernate 文档中指定的所有依赖项，但我仍然明白这一点。

如果您使用的是 Hibernate 3.5.x，您还需要以下 jar 文件。

hibernate-jpa-2.0-api-1.0.0-CR-1.jar

我遇到了同样的问题，添加这个解决了问题。
