类加载异常[org.hibernate.boot.registry.classloading.spi.ClassLoadingException]

Question

启动tomEE服务器时，我得到以下异常，我使用的hibernate和openejb版本分别是5.2和7.0.1。

在persistence.xml中，我已经给出了所需类的所有条目。同样，在War文件中，我可以看到对应的类，对于该类，我们得到了class not found异常。我可以在下面的链接中看到一些相关的问题，你是否看到我正在使用的版本的版本兼容性问题。

这个链接看起来像另一个问题，你能分享你的设置( WEB-INF/lib中的哪些库，persistence.xml在哪里，它的内容是什么)，也许是一个示例原因我有一些应用程序使用5.2.3最后的hibernate。

还要注意，对于tomee快照(如果您想尝试)，您需要设置

<property name="tomee.jpa.factory.lazy" value="true"/>

在hibernate生命周期persistence.xml起因中
