哪里有错！

[zhuweisyyc]

你用了缓存，却没有jar包，找下jar包吧。或者干掉下面的配置。 <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property> Caused by: java.lang.ClassNotFoundException: org.hibernate.cache.internal.NoCacheProvider

[Sam_zhouwei]

去掉这句配置<property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>

正解啊 要是添加包的 添加什么包
