Java Hibernate EntityManager工厂-EHCache

我在启动和运行entity manager工厂方面遇到了更多问题。不幸的是，错误信息非常模糊。我不太清楚为什么它不是更具描述性，但它是什么：

Hibernate启动日志消息跟踪级别，除创建此关系的所有启动消息外，没有任何实体以任何方式配置为简短相同的错误消息，或者…：

它总是死在一个地方。我过去遇到的问题是将我的项目分为50个子项目、30个模型项目、侦听器项目、过滤器项目、ui项目、web操作项目等。。我的一个项目仍然很可能没有使用最新版本，尽管不太可能导致这种类型的错误

这是我的log4j配置。我正在尝试将日志中的内容分开，这样我就可以更容易地识别问题来自何处，只需看看我需要什么来解决问题

休眠日志未显示错误。你为什么认为有什么不对劲？稍后是否有实际的错误消息？

我发现了问题。我必须在启动过程中附加一个调试器，以确定根本原因是类未找到异常。原因本身为空，这就是异常按原样记录的原因

我在这里混合和匹配了版本，很明显，我正在使用的缓存提供程序的类名发生了变化，这导致了整个混乱

主要是因为它没有启动。。。如果仔细观察，它在设置EHCache时会死掉。它永远不会完成该配置/安装。
