库存物资管理系统
一、背景资料：
1、有一个存放商品的仓库，每天都有商品出库和入库。
2、每种商品都有名称、生产厂家、型号、规格等。
3、出入库时必须填写出入库单据，单据包括商品名称、生产厂家、型号、
规格、数量、日期、时间、入库单位（或出库单位）名称、送货（或提货）人
姓名。
二、系统要求与功能设计
2.1 页面要求
（1）能够在 Tomcat 服务器中正确部署，并通过浏览器查看；（1 分）
（2）网站页面整体风格统一；
2.2 设计要求
1、设计出入库单据的录入。
2、实现按商品名称、出入库日期的查询。

查
查询商品信息,可以做到模糊查询
界面一search.jsp进行关键字模糊查询
界面二searchlist.jsp出现香港关键字信息
