我正在尝试将 Ehcache (2.6.0) 配置为 Hibernate (3.6.4) 二级缓存。我在 spring 上下文文件中设置了以下属性

<prop key="hibernate.cache.use_second_level_cache">true</prop>
<prop key="hibernate.cache.use_query_cache">true</prop>
<prop key="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory</prop>

当我启动应用程序时，它失败并出现以下异常：java.lang.ClassCastException: net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory cannot be cast to org.hibernate.cache.RegionFactory

这是堆栈跟踪：

Caused by: org.hibernate.HibernateException: could not instantiate RegionFactory [net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory]
    at org.hibernate.cfg.SettingsFactory.createRegionFactory(SettingsFactory.java:423)
    at org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:280)
    at org.hibernate.cfg.Configuration.buildSettingsInternal(Configuration.java:2863)
    at org.hibernate.cfg.Configuration.buildSettings(Configuration.java:2859)
    at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1870)
    Caused by: java.lang.ClassCastException: net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory cannot be cast to org.hibernate.cache.RegionFactory
    at org.hibernate.cfg.SettingsFactory.createRegionFactory(SettingsFactory.java:409)

我查看了源代码并观察到了这 SingletonEhCacheRegionFactory extends AbstractEhcacheRegionFactory一点AbstractEhcacheRegionFactory implements RegionFactory

SettingsFactory.java:409 的代码是

            return (RegionFactory) ReflectHelper.classForName( regionFactoryClassName )
                    .getConstructor( Properties.class )
                    .newInstance( properties );

一切似乎都到位，但我仍然得到例外。有什么线索吗？

您可以通过提供提供者类来尝试：

org.hibernate.cache.EhCacheProvider

并确保您已为 ehCache 添加了所需的 jar。
