介绍：

本软件系列到此，我已经全部写完了。

项目练习目标：

1、Java应用程序基本分析 2、培养面向对象编程的基本思想 3、Java基本设计模式综合应用 4、掌握分层和接口的基本设计 5、构建合理的Java应用程序包结构 6、综合应用JSE所学习的知识 7、在应用中合理使用集合框架 8、在应用中综合使用swing的常用组件 9、基本的表现层的实现机制 10、IO流和文件的基本操作 11、培养良好的Java编程习惯 12、培养调试Java程序的能力，培养改错的能力

项目功能需求：

1、能进行操作用户的注册，修改基本信息，删除和查询。 2、能对图书的基本信息进行增加、删除、修改和查询操作。 3、能填写进货单，一张进货单带有多条具体的进货信息，进货的书籍必须是图书管理里面已经有的；进货的同时修改库存对应书籍的存货量。 4、能填写销售单，一张销售单带有多条具体的销售信息，销售的书籍必须是图书管理里面已经有的，而且销售的数量不能超过当前库存的数量；销售的同时修改库存对应书籍的存货量。 5、可以查看库存的明细，可以按照条件进行查找具体的图书的库存值。 6、权限方面进行简化，做固定的权限控制。把用户按照模块分成不同操作权限的人员，特设一个admin的用户，可以操作全部的功能。

项目基本设计：

★ 架构设计整体框架、模块划分模块划分：用户、图书、进货、销售和库存5个模块

★ 系统功能结构设计每个功能模块的具体功能子模块

★ 数据库设计项目框架实现：分模块、分层、分包、构建应用程序

自己的总结：

这可以说是自己的第一个项目吧。小项目。O(∩_∩)O哈哈~、写到现在也有10多天了，自己比较享受写项目的这个过程，不过因为这个项目是跟着老师指导来做的，所以呢，自己的感触还不是很深，不过现在对分包啊，取名字啊，值对象封装啊，工厂方法，面向接口编程啊，表现层，逻辑层，数据层啊，这些以前用都没用过的，那时候完全不懂得怎么回事，不过在自己写了之后，感觉嘛、也就那么回事。 O(∩_∩)O~，这种项目开发，还是得自己多练练手，写得多了，自己就熟了。以后就是手到擒来。下面来看代码吧：

展示图片：

登录界面：

菜单项，除了注销是点亮之外，其他的都是暗的。

帮助界面：

当用户文件被删除了之后，就只能通过这个账号登录了。

管理员登录后的欢迎界面：

这个是管理员登录的欢迎界面，可以看到所有的菜单项都被点亮了的。

库存管理用户登录后的库存界面：

可以看到，菜单项只有库存那一项是点亮的。

销售管理用户登录后的销售界面：

可以看到，菜单项只有销售那一项是点亮的。

其他的都是，一个模块的用户对应相应的模块！

本系列就到此结束啦。可能有一些小bug，我也就没去改了，时间比较紧，O(∩_∩)O哈哈~，大家有兴趣的可以去改改，做做。
