出错原因
1.可能是因为映射文件( Order.hbm.xm)配置的class路径出错
<hibernate-mapping>
<class name="com.web.bean.Order" table="order">
<id name="orderId" type="java.lang.Integer" column="order_id">
<generator class="increment"></generator>
</id>
<property name="price" type="double" column="order_price" length="12"></property>
<property name="quantity" type="int" column="order_quantity"></property>
<property name="date" type="date" column="date" length="10"></property>
<many-to-one name="seller" column="seller_id" class="com.web.bean.Seller"
not-null="true">
</many-to-one>
<many-to-one name="phone" column="phone_id" class="com.web.bean.Phone"
not-null="true">
</many-to-one>
<many-to-one name="customer" column="customer_id" class="com.web.bean.Customer"
not-null="true">
</many-to-one>
</class>
</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
[color=red]<value>com/web/bean/Order.hbm.xml</value>[/color]
<property name="mappingResources">
<list>
<value>com/web/bean/Customer.hbm.xml</value>
<value>com/web/bean/Seller.hbm.xml</value>
<value>com/web/bean/Brand.hbm.xml</value>
<value>com/web/bean/Kind.hbm.xml</value>
<value>com/web/bean/Order.hbm.xml</value>
<value>com/web/bean/Phone.hbm.xml</value>
<value>com/web/bean/SellerOwnPhone.hbm.xml</value>
</list>
</property>
