库存物资管理系统实验要求如下：
1.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。
2.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。
3.评分标准：
1、A类：完全实现上述功能，达到A类标准的同学可以免于参加期末上机考试，
期末上机考试成绩按满分计算。
2、B类：实现出入库单据记录的添加。
3、C类：实现数据库的连接。
4、D类：不满足上述要求的。
详细过程：1.刚拿到题目，觉得貌似比上次的简单，因为看题目要求的篇幅并不多，但看完题后，思考编写的过程发现并不简单，题目能给的关键信息点太少；
2.首先编写必要的jsp界面，自己懒得写，是课前在网上见过的类似界面代码修改而成的，想省下点时间写关键的方法代码；
3.商品信息的录入和查询通过上次实验的学习已经基本掌握了，但是也费了半天时间弄，主要是不太熟悉，有些东西也是修改代码完成的；
4.接下来就是最头疼的那个出库，有点懵，我一开始想是不是还用考虑往外取物资的系统，瞎编了半天没结果，马上就快下机了，然后听说是没那么复杂，就是相当于上次学生管理系统的修改步骤，想着A标已经无妄了，就回宿舍参考了上次的那个系统又改了快一个多小时，终于磕磕巴巴的做出了个粗糙的程序。
总结：上次靠学长的代码完完全全的实现了功能，觉得下一次做系统应该差不多了，没想到只是按照人家的思路可以做下来，自己做一个新的系统，一些类似的死的东西道是没问题，出了个出库就直接懵了，还是缺乏自己的独立思考，不过这次就是同学提醒了一下思路就自己完成了，还算有进步了，时间花费比较多，以后要加快速度。
