hibernate - hibernate 插件库未添加

Question

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

Answer 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(如果使用Grails 3+，则为application.yml)内部的缓存工厂。
为此，您必须从以下位置设置字段:

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

至:

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

但是，您应该看看 page。它将向您说明为什么 必须使用休眠4.X EhCache而不是休眠3.X EhCache。
