Hibernate EntityManager 工厂 - EHCache

Question

我在启动和运行实体管理器工厂时遇到更多问题。不幸的是，错误消息非常模糊。我不太清楚为什么它不更具描述性，但它就是这样：

Hibernate 启动日志消息（跟踪级别），没有为简洁而配置实体（除了创建此关系或该关系的所有启动消息之外，无论哪种方式，错误消息都是相同的。 ..)：

它总是死在 EHCacheProvider 处。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、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）导致此类错误。

这是我的 log4j 配置。我试图将日志中的内容分开，以便我可以更轻松地辨别问题来自何处，并查看解决问题所需的内容。

Answer 1

您的休眠日志没有显示错误。为什么你觉得有什么不对劲？稍后有实际的错误消息吗？

Answer 2

我发现了问题所在。我必须在启动过程中附加一个调试器才能看到根本原因是类未找到异常。原因本身为 null，这就是异常按原样记录的原因。

我在这里混合并匹配了版本，显然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。
