我将 Spring 3.1 与 Hibernate 4 一起使用。在将 Ehcache 与 Hibernate 一起使用时，出现如下错误：

二级缓存未启用使用 [hibernate.cache.use_second_level_cache | hibernate.cache.use_query_cache]

即使我将 second_level_cache 设置为 true，我仍然会遇到同样的错误。这是我的定义，如果有人可以帮助我，我会很高兴。

感谢和问候，

这也在其他线程中进行了讨论删除以下行

<prop key="hibernate.cache.provider_class">

添加以下内容

<prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</prop>

Hibernate 3 和 Hibernate 4 将具有不同的配置。
