JAVA学习作品之销售管理系统
这套管理系统是本人学习JAVA一个月的作品，开发周期近10天左右，代码量约1500行，基于Eclipse JDK1.7，运用了Swing/SWT 开发工具Windowbuilder，配套的还包括JDBC驱动、以及微软的SQL Server数据库。源码全部开放，本人多轮测试，结果OK。由于本人初学JAVA，代码漏洞及不足之处难免，还请多多指正！实用方面，如果加入扫码器接口，软件应该会更完美！只是条件有限，仅为学习。
第一部分：首先看下软件信息，大小600k不到，双击运行，前提JDK1.7及以上环境配置好， SQL Server数据库安装好，数据库配置3个table如下图：
双击.jar程序，打开系统，界面如图：
工具栏两个选项：数据库管理、关于，主界面5大功能块进货、定价、销售、报废、报表。其他（未开发功能）。
点开工具栏数：据库管理，可以选择清除系统中旧数据，防止系统运行几年后数据累积增导致运行速度变慢：
点击两年前数据，弹出对话框，提示是否删除yyyy-mm-dd之前的数据，点击确定弹出清理成功！
点击关于，显示版本等信息：
点击主界面进货，进入进货管理界面，输入我们进货的信息：品名（商品名称）、数量、单位（销售单位，不支持单位换算）、总价（该数量下的总金额），录入如下信息
点击提交按钮，提示成功！（如果商品之前有记录过，输入商品名后，按Enter键，会自动带出商品单位）。 我们继续多输入一些其他商品。。。
点击定价，进入定价界面，界面左边两个按钮。 查找按钮：首先选择日期区间（系统默认一个月，我们调整为最近三天），起始和结束日期，对这一时间区间进货的商品指定销售价格
我们点击查找按钮，显示我们2016/03/20-2016/03/28的所有进货商品，系统自动计算出进货的价格，以此作为销售价格的参考
再看左下角的统一按比例加价（进货单价*比例）和 统一按固定值加价（进货单价+固定值），我们模拟比例加价25%，点击确定按钮，看下销售单价变化
当然销售单价可以手动改动，比如我们将雀巢咖啡的价格修改为22元/盒，直接更改后按Enter即可
确定好销售价格后，我们点提交按钮，提示提交成功！
再点击我们的销售功能，进入销售管理界面：下拉框直接选择商品，系统自动带出商品单位，如果上一步你有维护价格，系统也会自动带出销售价格，你只需要输入数量即可。
当然，如果没有维护销售价格，你可以手动输入单价，单价可以被手动调整
比如客户要买薯片2个，选择百事薯片，系统带出价格4.75（可以被修改），输入数量2个，点击>>按钮，加入购物车，总价9.5，我们多购买一些商品
如果我想将真彩水笔从购物车移除，选中点击删除按钮即可
如果同一商品多次加入购物车，系统会提示重复加入，请删除后，重新输入数量再次加入。最后，我们点击提交按钮，系统会计算购物车的总金额，提示是否提交
点是（Y），显示提交结果，交易成功。
回到主界面，点击报废功能，如有过期等原因导致报废，这个功能最实用了。选择商品，输入数量，按Enter键，显示成本，点击提交，显示报废成功！
再回到主界面，进入报表功能，这部分稍微复杂点，首先看报表界面。包含三大功能：记录、库存、利润。 在未锁定日期区间前，你不能进行任何操作。
我们选择最近一个月的记录，然后锁定日期，展开左边功能节点——记录：进货记录、销售记录、报废记录。 库存：当前库存（与日期区间无关）。 最后是利润分析（计算销售收入、成本之净利润。
比如我们点击销售记录：
如果在实际中，进货、报废、或者销售录入出错了，我们都可以在这里锁定日期，找到记录然后选中，鼠标右键选择删除记录
点击删除记录，提示删除的数据不加入报表计算，确认删除，提示删除成功
我们再看看当前剩余商品库存，帮助核对商品数量
最后是利润分析，这份报表十分重要
最后从这份报表来验证我们的操作结果：
1.康师傅红烧牛肉面：销售了5袋，每袋销售价格2.5，进货价格2.0，销售利润2.5，没有报废记录，净利润2.5
2.百事薯片：销售2份，每份销售价格4.75，进货价格3.8，销售利润1.9，其中有一份因为过期导致成本增加3.8，所以净利润亏1.9
........
最后总计销售利润和报废成本，得到净利润
好了，功能部分终于说完了。直接贡献代码部分，不用多做说明了，本人注释一向清楚：
