通过排查基本上断定是hibernate-tools的3.3.1版本不支持新的ehcache配置方式导致的。因为在我的hibernate.cgf.xml中，使用的是<property name="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</property>来配置ehcache的，这是ehcache新的配置方式，从异常的层级关系上看，应该是hibernate-tools插件本身不支持这配制方式，改用<property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.EhCacheProvider</property>来配制后问题解决。
