在项目中用到了hibernate,是通过在 jboss里设置一个jndi数据源去访问的，web环境下运行每问题 ，但是在用junit对其做单元测试时，启动hibernate报错

2982 [main] INFO org.hibernate.util.NamingHelper - JNDI InitialContext properties:{}
2982 [main] WARN org.hibernate.impl.SessionFactoryObjectFactory - Could not bind factory to JNDI

查了一下，原来是hibernate.cfg.xml文件中有个机关

<hibernate-configuration>
 <session-factory name="sample">

    ....

 </session-factory>
</hibernate-configuration>

当设置了session-factory元素的name属性时，hibernate会把session-factory注册到jndi中,因为我们单元测试是脱离web容器的，因此这个时候就报错了，只要把
