我将休眠版本从“hibernate4:4.3.6.1”（运行时）降级为“hibernate:3.6.10.18”。现在，当我运行我的 grails 应用程序时出现此错误：

【问题讨论】：

请在此处添加 Config.groovy。

标签： hibernate grails

【解决方案1】：

无法创建 Hibernate 缓存，因为找不到类 org.hibernate.cache.ehcache.EhCacheRegionFactory。因此，您必须更改 Config.groovy（或 application.yml，如果您使用 Grails 3+）中的缓存工厂。为此，您必须从以下位置设置字段：

hibernate.cache.region.factory_class: 'org.hibernate.cache.ehcache.EhCacheRegionFactory'

到：

hibernate.cache.region.factory_class: 'net.sf.ehcache.hibernate.EhCacheProvider'

不过，你应该看看这个page。它将向您解释为什么您必须使用 hibernate 4.X EhCache 而不是 hibernate 3.X EhCache。
