错哪了啊小献

adamed

sessionFactory
中除了要有hibernateProperties还需要MappingResources。
那里面配置了数据库表和bean的映射关系。。注意看你的org.hibernate.MappingException: Unknown entity: org.hjp.Usertable
就是说找不到Usertable对应的映射文件。。。

wenzhi057

应该是少的下面这个
<property name="mappingResources">
   <list>
      <value>org/eimhe/Users.hbm.xml</value>
   </list>
</property>
