hibernate.cfg.xml文件： <!-- Disable the second-level cache -->

<!-- <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property> -->

<property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>

绿色的是hibernate的官方的配置信息，但是初学hibernate的时候（本人初学）导入网友说的commons-logging-jar和ehcache-jar包也是不行的，只有把配置文件改成我注释掉的才可以，具体的原因我是不知道的，希望知道的网友可以解答。(最好导入我刚刚说的包)

将配置文件改为：<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
