本系统是一个独立的系统，用来解决企业采购信息的管理问题。采用JSP技术构建了一个
有效而且实用的企业采购信息管理平台，目的是为高效地完成对企业采购信息的管理。经过
对课题的深入分析，采购系统需实现以下功能模块：
各个模块实现的功能如下：
1.用户登录
对用户输入的用户名和密码进行匹配，只有合法的用户可以登录成功，进入主界面，
进行操作。是系统安全性的第一层保护层。
不同角色的用户登录（比如普通用户和超级管理员）的操作页面不一样。
2.供应商管理
灵活管理供货商，及时添加及修改供货商信息，为采购计划的制定提供保障。
3.材料管理
对材料进行管理，管理材料种类及库存，及时了解材料的库存信息，有助于做出正确
的采购选择。
4.订单管理
系统设计了多种订单。不同权限的操作员只能对其拥有权限操作的订单进行操作。
5.信息查询
