org.hibernate.cache.CacheException：HIBERNATE不支持动态创建JCache Cache对象

Question

我正在使用hibernate 5.3.3，hibernate-ehcache 5.3.1和ehcahe 3.2。用Java 8。

我在hibernate.cfg.xml中添加了以下配置

<property name="cache.use_second_level_cache">true</property>
<property name="cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory
</property>
<property name="hibernate.cache.use_query_cache">true</property>

我在我的实体类中添加了以下注释。

@Cacheable
@Cache(usage=CacheConcurrencyStrategy.READ_ONLY)

我在互联网上搜索但我没有找到以下异常的任何答案。

EhCacheRegionFactory用于连接Ehcache 2.x.你说你使用的是Ehcache 3.2，这很好。但它也意味着你应该使用org.hibernate.cache.jcache.JCacheRegionFactory来配置它。
