JAVA学习作品之销售管理系统V1.0
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,配套的还包含JDBC驱动、以及微软的SQL Server数据库。
源代码所有开放,本人多轮測试。结果OK。
因为本人初学JAVA,代码漏洞及不足之处难免,还请多多指正!
有用方面,假设增加扫码器接口,软件应该会更完美!仅仅是条件有限。仅为学习。
第一部分:首先看下软件信息,大小600k不到。双击执行。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例如以下图:
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。
其它(未开发功能)。
点开工具栏数:据库管理。能够选择清除系统中旧数据,防止系统执行几年后数据累积增导致执行速度变慢:
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,显示版本号等信息:
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),录入例如以下信息
点击提交button,提示成功!
(假设商品之前有记录过,输入商品名后,按Enter键,会自己主动带出商品单位)。 我们继续多输入一些其它商品。。。
点击定价,进入定价界面。界面左边两个button。
查找button:首先选择日期区间(系统默认一个月。我们调整为近期三天)。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button,显示我们2016/03/20-2016/03/28的全部进货商品。系统自己主动计算出进货的价格。以此作为销售价格的參考
再看左下角的统一按比例加价(进货单位价格*比例)和 统一按固定值加价(进货单位价格+固定值),我们模拟比例加价25%,点击确定button。看下销售单位价格变化
当然销售单位价格能够手动修改,比方我们将雀巢咖啡的价格修改为22元/盒。直接更改后按Enter就可以
确定好销售价格后,我们点提交button。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,系统自己主动带出商品单位。假设上一步你有维护价格,系统也会自己主动带出销售价格,你仅仅须要输入数量就可以。
当然,假设没有维护销售价格,你能够手动输入单位价格,单位价格能够被手动调整
比方客户要买薯片2个。选择百事薯片,系统带出价格4.75(能够被改动)。输入数量2个,点击>>button,增加购物车,总价9.5。我们多购买一些商品
假设我想将真彩水笔从购物车移除。选中点击删除button就可以
假设同一商品多次增加购物车。系统会提示反复增加。请删除后,又一次输入数量再次增加。
最后。我们点击提交button,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,这个功能最有用了。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,这部分略微复杂点,首先看报表界面。包括三大功能:记录、库存、利润。
在未锁定日期区间前,你不能进行不论什么操作。
我们选择近期一个月的记录,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。
比方我们点击销售记录:
假设在实际中,进货、报废、或者销售录入出错了,我们都能够在这里锁定日期。找到记录然后选中。鼠标右键选择删除记录
点击删除记录。提示删除的数据不增加报表计算。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。当中有一份由于过期导致成本添加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,功能部分最终说完了。直接贡献代码部分。不用多做说明了,本人凝视一向清楚:
第二部分:源代码
