## 第2个项目–企业客户关系管理系统 ##

创建我们的项目cms\_system，直接使用第1个后台项目的模板，将第1个后台项目jsp文件夹直接拷贝到项目的WEB-INF中，还有css,images等文件夹拷贝到WebRoot根路径下，如下图所示：

把登录页面上的大标题改过来

<h1>客户关系管理系统</h1>

把登录后的后台主页main/index.jsp上方的大标题改过来

<img src="${pageContext.request.contextPath }/images/y.jpg"
    					class="radius-circle rotate-hover" height="50" alt="" 
    					/>客户关系管理中心

Main/index.jsp页面上方引入标签库

<%@ taglib uri="http://java.sun.com/jsp/jstl/core"  prefix="c" %>

登录后在main/index.jsp上动态生成菜单

    			<span class="icon-user"></span>基本管理
