【j2ee spring】34、巴巴运动网的产品类别管理

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

这里我们先把上节的有几个工具类补足上来

PageIndex.java

/** * 功能：存放第一个页码和最后一个页码 * 时间：2015年5月19日09:06:26 * 文件：PageIndex.java * 作者：cutter_point */package com.cutter_point.bean; publicclass PageIndex{    privatelongstartpage;    privatelongendpage;             public PageIndex()    {    }     public PageIndex(long startpage, long endpage)    {        this.startpage = startpage;        this.endpage = endpage;    }       publiclong getStartpage()    {        returnstartpage;    }    publicvoid setStartpage(long startpage)    {        this.startpage = startpage;    }    publiclong getEndpage()    {        returnendpage;    }    publicvoid setEndpage(long endpage)    {        this.endpage = endpage;    }}

PageView.java
