2.可能原因：

在hibernate.cfg.xml文件中引入实例的时候出错：

引入实例有两种形式：

①配置为xml形式引入：

<!-- 引入资源配置文件 -->
<mapping resource="com/zrl/entity/Clazz.hbm.xml"/>
<mapping resource="com/zrl/entity/Student.hbm.xml"/>

此种方式参数引用为resource

②直接引入实体类，但每个实体类必须要有@Entity注解

<!-- 将带有entity注解的实体类进行注册 -->
<mapping class="com.zrl.entity1.Dept"/>
<mapping class="com.zrl.entity1.Employee"/>

此种方式参数引用为class

③当然也有可能是路径拼写出错
