IoC/DI(InverseofControl/DependencyInjection,控制反转/依赖注入)模式是一种企业级架构模式,通过将应用程序控制权反转交移给框架,并以构造器注入、属性设置器注入等方式将类实体注入到特定应用层中,最终实现层与层之间的解耦,使得应用程序获得良好的扩展性和应变能力。
客户需求如下:需要向系统中添加两个窗体,Engineers和Analysts,分别显示工程师和分析师的ID、Name和Credit(积分)。
在每个窗体左边有一个按钮,该按钮的作用是通过一种计算方式,算出工程师或者分析师的最终积分并显示在弹出窗体上。
对于工程师,最终积分=积分(Credit)*1.1;

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
