</hibernate-mapping>不加<value>com/shen/ec/entity/order.hbm.xml</value>不把错  加了就报错

Answer 1

order.hbm.xml你这个映射配置再检查检查，感觉像是映射类的时候出错了

Answer 2

你order.hbm.xml文件中com.shen.ec.entity.CartItem配置错误。

Answer 3

<hibernate-mapping package="com.shen.ec.entity">
<class name="Order" table="d_order">
<id name="id" column="id" type="integer">
<generator class="native"/>
</id>
<property name="orderNo" column="order_no" type="string"/>========================================================
type="integer"  ==> type="java.lang.Integer"
type="string"  ==> type="java.lang.String"

Answer 4

<one-to-many class="CartItem"/>这句有错？

Answer 5

<hibernate-mapping package="com.shen.ec.entity">
<class name="Order" table="d_order">
<id name="id" column="id" type="java.lang.Integer">
<generator class="native"/>

<one-to-many class="CartItem"/>
</set>
</class>
</hibernate-mapping>
木有用  还是老样子

Answer 6

com.shen.ec.entity.CartItem  是没映射在applicationContext里配好了就OK

Answer 7

可能是CartItem.hbm.xml 根本就没有这个文件 - -

Answer 8

Answer 9

补充：
      <bean id="CartProductDaoService" class="com.shen.ec.service.impl.CreateOrderServiceImpl">
<property name="dao">
<ref local="productQueryDao" />
</property>
</bean> 
好像这段出问题了    注释掉就不报错了

Answer 10

[com.shen.ec.dao.impl.ProductQueryDAOImpl] 没有　extends/implements[com.shen.ec.dao.OrderDao] 吧。
