巴巴运动网的产品类别管理
1、项目图解
这次我们做的是产品管理的功能，也就是增删改查。。。
2、首先我们引入相应的jar包
3、我们开始做我们的相应的功能模块
页面的素材我会上传的，链接是：http://download.csdn.net/detail/cutter_point/8803985
好的，这里我们开始对产品类型进行修改和查询操作

4、struts2的配置
<?xml version="1.0"encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD StrutsConfiguration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<include file="struts-default.xml" />
<constant name="struts.ObjectFactory" value="spring" /><!-- 表示这里面的action由spring进行创建 -->
<constant name="struts.devMode" value="true" />
<package name="control" namespace="/control"extends="struts-default">
<global-results>
<result name="message">/page/share/message.jsp</result>
</global-results>
<action name="center-*"><!-- 直接跳转，不需要经过class的验证，默认返回success -->
<result name="success">/page/controlcenter/{1}.jsp</result>
</action>
<action name="producttypelist" class="productTypeAction" method="execute">
<result name="list">/page/product/producttypelist.jsp</result>
</action>
<action name="*-producttypemanage" class="productTypeManageAction" method="{1}UI">
<result name="{1}">/page/product/{1}_productType.jsp</result>
</action>
<action name="producttypemanage-*" class="productTypeManageAction" method="{1}">
<result name="{1}">/page/product/{1}_productType.jsp</result>
</action>
</package>
</struts>
5、接下来我们测试一下页面的效果
我们访问这个网站
http://localhost:8080/babaSport_1000_producttypemanage_edit_find/control/center-main
我们把产品管理打开
这里就是分类了子类，前台第一页只显示初始的顶级父类
我们的修改功能
我们的查询功能
关于网站为什么要这样写，上一篇blog有介绍
6、总结
我们的增删改查其实没什么，也就是调用一下底层的接口，我们需要注意的是页面的struts2的标签的使用
