我不知道我哪里出错了..我的 Persistent 单元没有启动。

【问题讨论】：

你为什么要从你的部署中排除休眠？你看，你在部署hibernate时遇到了问题。
我这样做是因为 JBoss 7 具有内置的持久性休眠 4 提供程序以避免这种情况，并使用我的应用程序休眠版本，我将其排除在外。

标签： java spring hibernate jboss persistence

【解决方案1】：

由于您尝试使用打包在应用程序中的 Hibernate 4.x，因此您应该将 jboss.as.jpa.providerModule 属性设置为 application in your persistence.xml configuration file。

您最好更换 AS7 中的 Hibernate 4.0 模块，with a newer version though。这样，您无需在应用程序中打包 JPA 提供程序。

【解决方案2】：

ejb3 - 我的 lib 文件夹中存在持久性 jar，它与 mu hibernate jpa 2.0 jar 冲突。所以我添加了 pom.xml 中提供的范围。在那个类转换异常消失之后。
