1. 项目论证
1.1 项目概述（目标任务）
物资管理是企业管理非常重要的一环，它对企业的发展起着非常举足轻重的作用。由于物资的种类繁多，在各部门进出频繁，使得物资管理变得十分复杂。开发一套完善的物资管理系统不但可以使物资的管理者能够对物资的整个流程状态、库存状况了如指掌，并为决策管理提供科学依据，从而提高了管理水平和工作效率，而且可以使工作人员甩掉手工记账方式，从而最大限度地减少了手工操作带来的失误，达到事半功倍的效果。物资管理系统作为企业管理自动化、规范化的一部分，对提高企业管理效率、提高企业经济效益发挥不可替代的作用。
本系统开发目标是写一套完整的后勤资产管理系统,涵盖资产管理中的系统管理,权限管理,资产信息管理,物资采购管理,库存管理,入库、出库管理,借用、调用、领用管理,信息查询统计管理等主要模块,整个系统要求操作方便简单,功能完善,具备商业化气息,除了提供软件程序外还需提供比较完整的开发文档。
1.2 项目背景及必要性
后勤资产管理系统（B/S体系架构），需要实现当前各大后勤资产管理系统所提供的各种主要功能。目前国内各大后勤资产管理系统所提供的主要功能有，用户注册，删除用户，修改用户，仓库管理，物资采购，修改物资信息，删除物资信息，物资入库，物资出库，物资盘点，财产管理，房屋管理，耗材管理，数据备份，系统初始化。但考虑到开发时间和人力资源的具体情况，后勤资产管理系统只是初步实现其中的核心功能，去除了一些超出自己能力范围的一些内容。
后勤资产管理系统是企业内部很重要的一个管理事项，但目前企业内的管理，基本上是手工操作或是基于dos下的应用，这样对信息的管理者有诸多不便，有的系统对网络功能的支持程度不是很强，为以后软件升级到互联网带来了麻烦。因此有必要开发一个完全基于网络的管理系统，能在网络环境下实现数据的录入、插入、删除、查询、统计、更新、等功能。实现数字化管理。
1.3 项目开发的可行性
本系统采用JSP，Struts，Hibernate等技术开发，实现一次编写，到处运行。系统的多平台支持。基本上可以在所有平台上的任意环境中开发，在任意环境中进行系统部署，在任意环境中扩展。强大的可伸缩性。从只有一个小的Jar文件就可以Servlet/JSP，到由多台服务器进行集群和负载均衡，到多台Application进行事务处理，多样化和功能强大的开发工具支持。这一点与ASP很像，Java已经有了许多非常优秀的开发工具，而且许多可以免费得到，并且其中许多已经可以顺利的运行于多种平台之下。
Struts是实现MVC模式的通用框架，它由四个主要部分组成，模型、视图、控制器和XML文件。模型通常由Java Bean或EJB组件实现，负责处理业务逻辑；视图包括一组JSP文件，这些文件主要由JSP标签或客户化标签构成，它简化了JSP页面的编码工作Hibernate是一
