巴巴运动网的产品类别展示
1、项目图解
这里面好多页面都是错的，只是个模板，暂时用不上，需要的代码我会全部贴出来，最后做完的时候我会把项目发上来
2、首先我们引入相应的jar包
3、首先我们组装整个页面的整体格局
页面的素材我会上传的，链接是：http://download.csdn.net/detail/cutter_point/8803985

producttypelist.jsp
显示产品分类的页面
<%@ page isELIgnored="false"contentType="text/html;charset=UTF-8" %><%@taglib uri="/struts-tags" prefix="s"%><html><head><title>产品类别管理</title><meta http-equiv="Content-Type"content="text/html; charset=UTF-8"><link rel="stylesheet"href="../css/vip.css" type="text/css"><script type="text/javascript"> //到指定的分页页面 function topage(page) { document.getElementById("page").value = page; //alert(document.getElementById("page").value); //document.form1.method= 'post'; //document.form1.submit(); var obj = document.getElementsByName("form1").item(0).submit(); } </script><SCRIPT language=JavaScriptsrc="../js/FoshanRen.js"></SCRIPT></head> <body bgcolor="#FFFFFF"text="#000000" marginwidth="0" marginheight="0"><form id="form11"name="form1" action="producttype"method="post"><s:hidden id="page"name="page" /> <table width="98%" border="0"cellspacing="1" cellpadding="2"align="center"> <tr ><td colspan="6" bgcolor="6f8ac4" align="right" > <%@ include file="../share/fenye.jsp" %> </td></tr> <tr> <td width="8%" bgcolor="6f8ac4"><div align="center"><fontcolor="#FFFFFF">代号</font></div></td> <td width="5%" nowrapbgcolor="6f8ac4"><div align="center"><fontcolor="#FFFFFF">修改</font></div></td> <td width="20%" bgcolor="6f8ac4"><div align="center"><fontcolor="#FFFFFF">产品类别名称</font></div></td> <td width="10%"nowrap bgcolor="6f8ac4"><div align="center"><fontcolor="#FFFFFF">创建下级类别</font></div></td> <td width="15%"bgcolor="6f8ac4"><div align="center"><fontcolor="#FFFFFF">所属父类</font></div></td> <td nowrapbgcolor="6f8ac4"><div align="center"><fontcolor="#FFFFFF">备注</font></div></td> </tr><!---------------------------LOOPSTART------------------------------><s:iterator value="#request.pageView.records"var="productType"> <tr> <td bgcolor="f5f5f5"><div align="center"><s:propertyvalue="#productType.typeid"/></div></td> <td bgcolor="f5f5f5"><div align="center"> <img src="../images/edit.gif"width="15" height="16"border="0"></a></div></td> <td bgcolor="f5f5f5"><div align="center"><a href=""><s:property value="#productType.name"/></a></div></td> <td bgcolor="f5f5f5"><div align="center"><a href="<s:url action="/control/product/type/manage"/>?method=addUI&parentid=#">创建子类别</a></div></td> <td bgcolor="f5f5f5"align="center"><s:if test="%{#productType.parent!= null}"><s:property value="#productType.parent"/></s:if></td> <td bgcolor="f5f5f5"><s:propertyvalue="#productType.note"/></td> </tr></s:iterator> <!----------------------LOOPEND-------------------------------> <tr> <td bgcolor="f5f5f5" colspan="6"align="center"><table width="100%"border="0" cellspacing="1"cellpadding="3"> <tr> <td width="5%"></td> <td width="85%"> <input name="AddDic"type="button" class="frm_btn"id="AddDic" onClick="javascript:"value="添加类别"> <input name="query"type="button" class="frm_btn"id="query" onClick="javascript:"value=" 查询 "> </td> </tr> </table></td> </tr> </table> </form></body></html>
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"> <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="producttype" class="productTypeAction" method="execute"> <result name="list">/page/product/producttypelist.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_0800_s2sh_producttypelist_web/control/center-main
我们把产品管理打开
由于所属父类展示没做，所以还无法显示
关于网站为什么要这样写，上一篇blog有介绍
6、总结
下一节我们将会开始处理父类的子类的子类的子类。。。
显示问题了，这里我们先把数据库里面所有的类别全部查询出来，不考虑所谓的先只显示父类的问题
