在使用Hibernate4做二级缓存的测试（HashtableCacheProvider）时，会报如下异常： 
org.hibernate.service.spi.ServiceException: Unable to create requested service \[org.hibernate.engine.spi.CacheImplementor\]

主要原因有下： 
1. [![Unable to create requested service \[org.hibernate.engine.spi.CacheImple][Unable_wbr_to_wbr_create_wbr_requested_wbr_service_wbr_org.hibernate.engine.spi.CacheImple]][Unable_wbr_to_wbr_create_wbr_requested_wbr_service_wbr_org.hibernate.engine.spi.CacheImple_Unable_wbr_to_wbr_create_wbr_requested_wbr_service_wbr_org.hibernate.engine.spi.CacheImple] 
2.在org.hibernate.cache包下面缺少很多class文件，如HashtableCacheProvider.class等，你可以将hibernate3中org.hibernate.cache下面的文件拷贝到hibernate4的核心j ar包下，或者使用Hibernate3的核心jar包。
