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>
