出现这个问题的原因极大可能的是 hbm的配置文件出错了，或者根本就没有配置。在控制台的报错信息，下面会有Cause By的信息，会提示是由什么问题引发的。

**（1）检查是否配置hbm配置文件**  
解决办法：  
在实体类的同包下添加，即可。

User.hbm.xml  内容
    	<?xml version="1.0" encoding="UTF-8"?>
    	<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
    	    
    	<hibernate-mapping>
    		<class name="cn.itcast.shop.user.vo.User" table="user">
    			<id name="uid">
    				<generator class="native"/>
    			</id>
    			<property name="username"/>
    			<property name="password"/>
    			<property name="name"/>
    			<property name="email"/>
    			<property name="phone"/>
    			<property name="addr"/>
    			<property name="state"/>
    			<property name="code"/>
    			
    			<set name="orders" cascade="delete">
    				<key column="uid"/>
    				<one-to-many class="cn.itcast.shop.order.vo.Order"/>
    			</set>
    		</class>
    	</hibernate-mapping>

**（2）检查配置文件hbm中是否有打错**

错误原因由：找不到字段为“tatal”在该包中。 对比发现，是“total”打错了。
