1、Java程序设计期末课程设计报告题 目 超市进销存管理系统 班 级： 13级信息安全班 学 号： 姓 名： 成 绩： 完成时间： 2014 年 12 月目 录一、需求分析3二、系统简介3三数据准备3四、数据库结构6五、系统实现与核心代码8六、系统的运行结果16七、心得与体会18八、参考书目18一.需求分析企业进销存管理系统的主要工作，是对企业的进货、销售和库存以信息化的方式进行管理，最大限度的减少各个环境中可能出现的错误，有效减少盲目采购，降低采购成本、合理控制库存、减少资金占用并提高市场灵敏度，使企业能够合理安排进、销、存的每个关键步骤，替身企业市场竞争力。针对经营管理中存在的问题，兰州华联
2、超市对产品的进销存合理化提出了更高的要求。 通过实际调查，要求企业进销存管理系统具有以下功能。 界面设计美观大方，方便、快捷、操作灵活。实现强大的进销存管理，包括基本信息、进货、销售和库存管理。能够在不同的操作系统下运行，不局限于特定的平台。提供数据库备份与恢复功能。提供库存盘点功能。提供技术支持的联系方式，可以使用邮件进行沟通，或者直接连接到技术网站。二.分析与设计：(1)功能模块划分:本进销存管理系统划分为六个模块，分别为系统登陆模块，系统主窗体设计模块，进货单模块，销售单模块，库存盘点模块和数据库备份与恢复模块，(2)数据库结构描述:企业进销存管理系统需要使用数据库存储和管理进销存过程中
3、的所有信息，本企业进销存管理系统使用Access数据库系统作为后台数据库，数据库名称为db_database28。其中包含了14张数据表两个视图。以下是系统主要涉及的六个数据库表：1 供应商信息表：主要用于存储供应商详细信息，其结构如下表所示：User表：Handle表：Product表：Stuff表：Yield表：空表等待插入数据。三.系统详细设计文档：1.系统流程图： (1)系统功能结构图： (2)系统业务流程图： (3)系统中的主要类及功能： 1.Item公共类：Item公共类是对数据表最常用的ID和name属性的封装，属于swing列表，表格，下拉列表框等组件的赋值。该类重写了toSt
4、ring()方法，在该方法中只输出name属性。但是在获取组件的内容时，获取的是Item类的对象，从该对象中可以获取ID的属性，然后通过该属性到数据库中获取唯一的数据。 2.数据模型公共类： 数据模型公共类对应着数据库中不同的数据表，这些模型将被访问数据库的Dao类和程序中各个模块甚至各个组件使用，数据模型是对数据表所有字段的封装，它是纯粹的模型类，他也要重写toString()方法，另外还要重写hashCode()方法和equal()方法。它主要用于存贮数据，并通过相应的getXXX()方法和setXXX()实现不同属性的访问原则。 3.Dao公共类： Dao类实现了数据库的驱动，连接，关闭
5、和多个操作数据库的方法，Dao类不需要创建对象，可以直接调用类中的所有数据库操作方法。Dao类自定义的主要方法有getKhlnfo(Item item)方法，主要是获取客户信息，方法的返回值是tKhlnfo的对象，及客户信息的数据模型。getGyslnfo(Item item)方法，主要是获取供应商信息，返回值是Gyslnfo类的对象，及供应商数据表的模型对象。getSplnfo(Item item)方法，主要用于获取商品信息，返回值是Splnfo类的对象，及商品数据表的数据模型。getLogin(String name,String password)方法主要适用于判断登录用户的用户名与密码
6、是否正确，返回值是boolean类型。insertSelllnfo(TbSellMain sellMain)方法，主要是添加销售信息到数据库中。restoreOrBackup(String sql)方法，此方法是设置数据库的模式为单用户连接模式，这样可以避免数据库恢复或备份时失败。checkLogin(String userStr,String passStr)方法，用于判断登录用户与密码是否正确。(2)各个模块实现方法描述： 1.系统登录模块 实现该模块的主要代码如下 package src;import java.awt.AlphaComposite;import java.awt.Gra
