我是靠谱客的博主甜美帆布鞋，最近开发中收集的这篇文章主要介绍关于struts action 提交2次的问题 ---继续，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

8) ，
说的不如给你们看
一：接口BO DmOrderPriceImpl
public List queryChargeType(int priceId) {
// TODO 自动生成方法存根

return this.dmOrderPriceDao.queryDmChargeType(priceId);
}
二：接口 Dao DmOrderPriceDaoImpl
public List queryDmChargeType(int priceId) {
// TODO 自动生成方法存根
String hql="from DmChargeType as d left join fetch d.dmOrderPrice as dp where dp.id="+priceId;
return this.hibernateTemplate.find(hql);
}
三：配置文件
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<class name="com.superman.model.DmChargeType" table="dm_chargeType" catalog="sanco_superman">
<id name="id" type="java.lang.Integer">
<column name="id" />
<generator class="identity" />
</id>
<many-to-one name="dmOrderPrice" class="com.superman.model.DmOrderPrice" fetch="select">
<column name="dm_priceId" />
</many-to-one>
<property name="max" type="java.lang.Integer">
<column name="max" />
</property>
<property name="min" type="java.lang.Integer">
<column name="min" />
</property>
<property name="cost" type="java.lang.Float">
<column name="cost" precision="9" scale="3" />
</property>
</class>
</hibernate-mapping>
主键表：
<hibernate-mapping>
<class name="com.superman.model.DmOrderPrice" table="dm_order_price" catalog="sanco_superman">
<id name="id" type="java.lang.Integer">
<column name="id" />
<generator class="identity" />
</id>
<property name="price" type="java.lang.Float">
<column name="price" precision="9" scale="3" />
</property>
<set name="dmChargeTypes" inverse="true">
<key>
<column name="dm_priceId" />
</key>
<one-to-many class="com.superman.model.DmChargeType" />
</set>
</class>
</hibernate-mapping>

struts.config
<form-bean name="dmOrderPriceForm" type="com.sanco.supperman.struts.form.DmOrderPriceForm" />
<action
attribute="dmOrderPriceForm"
name="dmOrderPriceForm"
parameter="method"
path="/xwfbadmin/admin/manage/dmManager/addChargeType"
scope="request"
type="com.sanco.supperman.struts.action.AddChargeTypeAction">
<forward name="init" path="/xwfbadmin/admin/manage/dmManager/addChargeType.do?method=init" />
<forward name="success" path="/xwfbadmin/admin/manage/dmManager/dmChargeType_add.jsp" />
</action>
四：页面
提交过来的页面（没有javascript --|||,这我还是晓得看的）

</logic:iterate>
</table>
</logic:present>
</body>
</html>
显示成功的页面

五：action
public class AddChargeTypeAction extends DispatchAction {
/*
* Generated Methods
*/
private Object getBean(String name)
{
return MyBeanDelegate.getInstance().getBean(name);
}
private IDmOrderPriceBo dmOrderPriceBo=(IDmOrderPriceBo)getBean("dmOrderPricebo");
/**
* Method execute
* @param mapping
* @param form
* @param request
* @param response
* @return ActionForward
*/
public ActionForward init(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
DmOrderPriceForm dmOrderPriceForm = (DmOrderPriceForm) form;// TODO Auto-generated method stub
//查询所有这个价格的折扣区间
String id=request.getParameter("id");

List list=null;
[color=green]list=dmOrderPriceBo.queryChargeType(Integer.valueOf(id));[/color] request.setAttribute("emplist", list);
request.setAttribute("priceId", id);

return mapping.findForward("success");
}
}

我页面上是用的EL表达式打出来的，去掉也好了，不知道EL为什么不行？？完全没得道理。
能够看出原因的，我称他为神，女的就以身相许！
