笔记：图形报表

思路：修改data.xml文件，把数据拼接到里面去

第一步：下载解压后把components文件拷贝到webapp目录下

第二步：webapp目录下创建run目录把stat文件拷贝到这里

第三步：jsp入口：

<div class="panel">        <div class="panel_icon"><img src="${ctx}/skin/default/images/icon/cubes.png" /></div>        <div class="panel-header">        <div class="panel-title">统计报表</div>                <div class="panel-content"><ul><li><a href="${pageContext.request.contextPath}/run/stat/factorySale.action" target="main" id="aa_1">厂家销售情况统计</a></li><li><a href="${pageContext.request.contextPath}/run/stat/productSale.action" target="main" id="aa_1">产品销售排行</a></li><li><a href="${pageContext.request.contextPath}/run/stat/onlineInfo.action" target="main" id="aa_1">系统访问压力图</a></li></ul>        </div>        </div>    </div>

第四步：controller

用到的工具类：（生成utf-8格式的xml文件）只是用到了里面两个方法，其他方法没用
