如果出现这个问题是因为如下的配置有问题不是代码原因：

<!-- 高速缓存提供程序 -->
<property name="hibernate.cache.region.factory_class">
    net.sf.ehcache.hibernate.EhCacheRegionFactory
</property> 这个配置有问题

 

将该配置文件改为：

<!-- 高速缓存提供程序 -->
<property name="hibernate.cache.region.factory_class">
    org.hibernate.cache.ehcache.EhCacheRegionFactory
</property>
