【问题描述】：
首先 我正在尝试将 Hibernate 3.6 升级到 5.2.3，第一次遇到二级缓存的问题，它曾经是
configuration.setProperty(Environment.CACHE_PROVIDER,"org.hibernate.cache.HashtableCacheProvider");
由于hibernate 5没有CACH_PROVIDER，所以我改成config.setProperty(Environment.CACHE_REGION_FACTORY,"org.hibernate.cache.ehcache.EhCacheRegionFactory");
不知道这是否相关，这是堆栈跟踪：

另一件事是，由于我是从休眠 3 升级到休眠 5，似乎没有一个很好的迁移过程教程，因为它做了很多更改，我是否必须从休眠 3 迁移到 4，然后4比5？或任何建议将不胜感激。谢谢。

如果您尚未解决此问题，我建议您逐步迁移。 Hibernate 4 中有很多新的变化，特别是如果您使用事件侦听器，它们的新 Integrator 机制。我们刚刚完成了这个过程，这里有更详细的描述：otter606.wordpress.com/2017/02/12/…
