nested exception is org.hibernate.MappingException解决方案

1.可能是因为映射文件( Order.hbm.xm)配置的class路径出错 

1. <hibernate-mapping>  
2.  <class name="com.web.bean.Order" table="order">  
3.   <id name="orderId" type="java.lang.Integer" column="order_id">  
4.    <generator class="increment"></generator>  
5.   </id>  
6.   <property name="price" type="double" column="order_price" length="12"></property>  
7.   <property name="quantity" type="int" column="order_quantity"></property>  
8.   <property name="date" type="date" column="date" length="10"></property>  
9.   <many-to-one name="seller" column="seller_id" class="com.web.bean.Seller"  
10.    not-null="true">  
11.   </many-to-one>  
12.   <many-to-one name="phone" column="phone_id" class="com.web.bean.Phone"  
13.    not-null="true">  
14.   </many-to-one>  
15.   <many-to-one name="customer" column="customer_id" class="com.web.bean.Customer"  
16.    not-null="true">  
17.   </many-to-one>  
18.  </class>  
19. </hibernate-mapping>  

类的路径必须写全，或者在<hibernate-mapping>中加上属性package="com.web.bean" 

2.如果以上检查都是对的，那么就看applicationContext.xml中是否加上了 
<value>com/web/bean/Order.hbm.xml</value> 

1. <property name="mappingResources">  
2.    <list>  
3.     <value>com/web/bean/Customer.hbm.xml</value>  
4.     <value>com/web/bean/Seller.hbm.xml</value>  
5.     <value>com/web/bean/Brand.hbm.xml</value>  
6.     <value>com/web/bean/Kind.hbm.xml</value>  
7.     <value>com/web/bean/Order.hbm.xml</value>  
8.     <value>com/web/bean/Phone.hbm.xml</value>  
9.     <value>com/web/bean/SellerOwnPhone.hbm.xml</value>  
10.    </list>  
11.  </property>
