SSH(struts+spring+hibernate)迅速开发--第八章 浏览和选购商品（2）

 

1．    注册ShopService

同用户注册模块里面的UserService服务的注册一样，我们在applicationContext-service.xml配置文件中，配置ShopService的服务，以及它的方法的Spring事务管理，具体配置是在applicationContext-service.xml添加如下配置：

<!-- 商品查看定购服务 -->

   <!—配置商品服务三个方法的Spring事务管理à

       <bean id="shopServiceProxy" parent="baseServiceProxy">

              <property name="target">

                     <ref bean="shopService" />

              </property>

 

              <property name="transactionAttributes">

                     <props>

                            <prop key="find*">PROPAGATION_REQUIRED</prop>

                            <!--

                            <prop key="findShopsMsg">PROPAGATION_REQUIRED</prop>

                             -->

                            <prop key="*">PROPAGATION_REQUIRED,readOnly</prop>

                     </props>

              </property>

       </bean>

       <!—注册商品服务 à

       <bean id="shopService"

             class="cn.com.book.demo.services.impl.ShopServicesImpl">

           <property name="shopDAO">

               <ref bean="ShopDAO"/>

           </property>

       </bean>

2．    编写Form和Action

因为我们在这里没有需要实现表单校验，所以ShopForm就直接继承ActionForm实现，结合页面需要的信息，我们可以整理出ShopForm.java的清单如下：

/*

 * Generated by MyEclipse Struts

 * Template path: templates/java/JavaClass.vtl

 */

package cn.com.book.demo.struts.form;

 

import java.util.List;

 

import javax.servlet.http.HttpServletRequest;

 

import org.apache.struts.action.ActionErrors;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionMapping;

 

/**

 * MyEclipse Struts

 * Creation date: 12-11-2007

 *

 * XDoclet definition:

 * @struts.form name="shopForm"

 */

public class ShopForm extends ActionForm {

       private String shopName;  //商品名称

       private int shopId;// 商品编号

       private double price;//商品价格

       private List shops;//商品集合

       private int targetPage = 1;//当前页码

       private int totalPage;//页码总数

       private int shopAmount;//商品数量

       private boolean hasFirst = false;//是否显示首页

       private boolean hasPrev = false;//是否显示前一页

       private boolean hasNext = false;//是否显示下一页

       private boolean hasLast = false;//是否显示末页

      

       /*

        * Generated Methods

        */

 

       public double getPrice() {

              return price;

       }

 

       public void setPrice(double price) {

              this.price = price;

       }

 

       public int getShopId() {

              return shopId;

       }

 

       public void setShopId(int shopId) {

              this.shopId = shopId;

       }

 

       public String getShopName() {

              return shopName;

       }

 

       public void setShopName(String shopName) {

              this.shopName = shopName;

       }

 

       public List getShops() {

              return shops;

       }

 

       public void setShops(List shops) {

              this.shops = shops;

       }

 

       /**

        * Method validate

        * @param mapping

        * @param request

        * @return ActionErrors

        */

       public ActionErrors validate(ActionMapping mapping,

                     HttpServletRequest request) {

              // TODO Auto-generated method stub

              return null;

       }

 

       /**

        * Method reset

        * @param mapping

        * @param request

        */

       public void reset(ActionMapping mapping, HttpServletRequest request) {

              // TODO Auto-generated method stub

       }

 

       public boolean isHasFirst() {

              return hasFirst;

       }

 

       public void setHasFirst(boolean hasFirst) {

              this.hasFirst = hasFirst;

       }

 

       public boolean isHasLast() {

              return hasLast;

       }

 

       public void setHasLast(boolean hasLast) {

              this.hasLast = hasLast;

       }

 

       public boolean isHasNext() {

              return hasNext;

       }

 

       public void setHasNext(boolean hasNext) {

              this.hasNext = hasNext;

       }

 

       public boolean isHasPrev() {

              return hasPrev;

       }

 

       public void setHasPrev(boolean hasPrev) {

              this.hasPrev = hasPrev;

       }

 

       public int getTargetPage() {

              return targetPage;

       }

 

       public void setTargetPage(int targetPage) {

              this.targetPage = targetPage;

       }

 

       public int getTotalPage() {

              return totalPage;

       }

 

       public void setTotalPage(int totalPage) {

              this.totalPage = totalPage;

       }

 

       public int getShopAmount() {

              return shopAmount;

       }

 

       public void setShopAmount(int shopAmount) {

              this.shopAmount = shopAmount;

       }

}
