我在启动和运行实体管理器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，但它就是它：
Hibernate启动日志消息（跟踪级别），没有为简洁而配置的实体（除了创建此关系的所有启动消息之外，都是相同的错误消息）：

它总是在EHCacheProvider死掉。我过去遇到的问题是我将项目分成50个子项目（30个模型项目，监听项目，过滤项目，ui项目，网络行动项目等）。我的一个项目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，以便我可以更轻松地识别问题的来源，并查看解决问题所需的内容。

答案 0 :(得分：0)
你的休眠日志没有显示错误。为什么你认为有什么不对？以后是否有实际的错误消息？
答案 1 :(得分：0)
我发现了问题。我必须将一个调试器附加到启动过程，以查看根本原因是找不到类的异常。原因本身是null，这就是为什么异常被记录的原因。
我在这里混合和匹配的版本显然为我正在使用的缓存提供程序更改了一个类名，这导致了整个混乱。
