<content type="html"><![CDATA[<p>每个公司的项目管理流程都不尽相同，但是都值得参考，画出流程不意味就是条条框框了，而是让大家有章可循，流程不是限制效率而是促进整体效率，并且流程是需要持续迭代优化的。千万不要说流程影响效率，这样的认知，让人怀疑你的管理和认知水平，不要以为混乱无序就会效率高。影响效率的从来不是流程，流程会让整体效率最大，而不是满足那些事前拍脑袋，事后拍大腿的想法。规范完善的流程永远比混乱无序带来更高的效率，所有说没有流程效率才高的，只是满足你所谓的拍脑袋而已。</p><h1 id="1-需求池"><a href="#1-需求池" class="headerlink" title="1 需求池"></a>1 需求池</h1><p>从产品经理、技术团队、用户反馈等渠道收集需求，集中在产品组的需求池中。每次版本迭代会从需求池中筛选优先级、重要性、紧急程度比较高的需求，形成需求列表初稿，供评审。</p><h1 id="2-产品功能列表及PRD"><a href="#2-产品功能列表及PRD" class="headerlink" title="2 产品功能列表及PRD"></a>2 产品功能列表及PRD</h1><p>经过产品组及项目组内部（含产品、开发、测试、UED、交互、项目等）评审，会输出确定的产品功能列表及优先级。列表及优先级的输出，需要同步考虑项目周期、人力资源等情况。产品经理经讨论，输出PRD（Product Requirement Document-产品需求文档）。</p><a id="more"></a><h1 id="3-评审会"><a href="#3-评审会" class="headerlink" title="3 评审会"></a>3 评审会</h1><p>产品/项目经理组织相关人员进行需求评审，针对需求的可实现性、合理性、风险、工期等做出评估。评审会通常会进行2-3轮，根据每次会议结果，产品经理会更新、补充文档，以便进入下一轮评审。</p><h1 id="4-规划会议"><a href="#4-规划会议" class="headerlink" title="4 规划会议"></a>4 规划会议</h1><p>根据基本定稿的需求，评估需要的人力资源及技能要求；根据整体的需求情况及人力资源情况等，评估整体的项目周期；讨论风险及解决预案等。</p><h1 id="5-任务分解"><a href="#5-任务分解" class="headerlink" title="5 任务分解"></a>5 任务分解</h1><p>将项目所有工作进行逐级逐层分解，分解至不可再拆分、单一资源可完成；单任务的完成时间尽量控制在3个工作日内。任务分解后，需分配到相应的人员，并做详细时间的评估。</p><h1 id="6-实施"><a href="#6-实施" class="headerlink" title="6 实施"></a>6 实施</h1><p>计划完成，即可进入正式的项目实施阶段。首先需要召开正式的项目立项会（开踢会）；项目过程中，每日召开晨会，同步进度及时暴露解决问题；项目经理每日下班输出项目日报；使用禅道系统进行需求、任务、BUG等管理。</p><h1 id="7-测试"><a href="#7-测试" class="headerlink" title="7 测试"></a>7 测试</h1><p>提交测试后，需先进行灰度环境发布测试；通过后进行正式环境发布测试，需要注意对已上线版本相关功能的影响；抽取线上少量真实用户做Beta测试，验证版本的稳定性，修改严重问题、降低全量上线时的风险。测试工作不仅限于测试组，也需产品、交互、UED等相关环节进行验证。</p><h1 id="8-项目交付，全量发布"><a href="#8-项目交付，全量发布" class="headerlink" title="8 项目交付，全量发布"></a>8 项目交付，全量发布</h1><p>项目交付，全渠道上线，即正式对外发布，注意做好风险预备方案。</p><h1 id="9-收集用户反馈"><a href="#9-收集用户反馈" class="headerlink" title="9 收集用户反馈"></a>9 收集用户反馈</h1><p>版本上线后，需及时收集用户的反馈；收集渠道：用户反馈后台、用户来电、市场渠道评论、用户群反馈等。</p><h1 id="10-项目总结会"><a href="#10-项目总结会" class="headerlink" title="10 项目总结会"></a>10 项目总结会</h1><p>通常在发版后进行，回顾项目历程，总结得失、明确坚持与改进，数据分享、表彰项目之星等。</p><p><img src="/2022/08/12/%E7%AE%80%E6%98%8E%E9%A1%B9%E7%9B%AE%E7%AE%A1%E7%90%86%E6%B5%81%E7%A8%8B/640.png" alt="项目管理流程"></p>]]></content>

<content type="html"><![CDATA[<h1 id="1-简介"><a href="#1-简介" class="headerlink" title="1 简介"></a>1 简介</h1><p>本文讲解如何基于premake5创建一个典型的C++解决方案，该解决方案包含三个项目：</p><ul><li>一个依赖GLFW动态库的动态库项目ExampleDll</li><li>一个依赖ExampleDll动态库的窗口程序APP</li><li>一个基于Catch的单元测试程序UnitTest</li></ul><a

title="3 文件的组织结构"></a>3 文件的组织结构</h1><p>首先需要确定整个解决方案中源代码、三方库、二进制等文件的组织结构，本文创建的文件结构如下：</p><blockquote><p>premakeExample/<br> |–premake5.lua （premake脚本文件）<br> |–prj/ (生成的解决方案与各项目配置文件路径)<br> |–build/<br> | |–target/ (目标生成路径)<br> | |–obj/ （中间文件生成路径）<br> |–bin/ (最终发布的二进制文件路径)<br> |–3rd/ (第三方库文件路径)<br> | |–Catch (Catch单元测试框架头文件路径)<br> | |–glfw （glfw三方库相关文件路径） </p></blockquote><h1 id="4-下载所需文件"><a href="#4-下载所需文件" class="headerlink" title="4 下载所需文件"></a>4 下载所需文件</h1><ul><li>premake5.exe <a href="https://github.com/premake/premake-core/releases"

<content type="html"><![CDATA[<h1 id="1-单一职责原则-Single-Responsibility-Principle"><a href="#1-单一职责原则-Single-Responsibility-Principle" class="headerlink" title="1 单一职责原则(Single Responsibility Principle)"></a>1 单一职责原则(Single Responsibility Principle)</h1><p>目的：降低代码复杂度、系统解耦合、提高可读性</p><p>含义：对于一个类，只有一个引起该类变化的原因；该类的职责是唯一的，且这个职责是唯一引起其他类变化的原因。</p><p>解决：将不同的职责封装到不同的类或者模块中。 当有新的需求将现有的职责分为颗粒度更小的职责的时候，应该及时对现有代码进行重构。当系统逻辑足够简单，方法足够少，子类够少或后续关联够少时，也可以不必严格遵循你SRP原则，避免过度设计、颗粒化过于严重。</p><a id="more"></a><p>实例：电线类Wire为居民供电，电压为220v；但是新的需求增加，电线也输送高压电，电压为200kv，原有电线类可以增加方法实现扩充，这就违背了单一职责原则。可以提供基类，创建两个派生类，居民供电线、高压输电线。</p><h1 id="2-里氏代换原则（Liskov-Substitution-Principle）"><a href="#2-里氏代换原则（Liskov-Substitution-Principle）" class="headerlink" title="2 里氏代换原则（Liskov Substitution Principle）"></a>2 里氏代换原则（Liskov Substitution Principle）</h1><p>目的：避免系统继承体系被破坏</p><p>含义：所有引用基类的地方必须能透明地使用其子类的对象。</p><p>解决：子类可以实现父类的抽象方法，但是不能覆盖父类的非抽象方法；子类中可以增加自己特有的方法；当子类覆盖或实现父类的方法时，方法的前置条件（即方法的形参）要比父类方法的输入参数更宽松；当子类的方法实现父类的抽象方法时，方法的后置条件（即方法的返回值）要比父类更严格。如果子类不能完整地实现父类的方法，或者父类的一些方法在子类中已经发生畸变，则建议断开继承关系，采用依赖，聚合，组合等关系代替继承。</p><p>实例：已经定义鸟类具有两个翅膀飞的方法；新加入鸵鸟，不会飞，如果覆盖父类的方法，在两个翅膀飞的方法中什么也不做，就违背里氏替换原则，导致所有鸟都不会飞。应该创建并列的两种鸟基类，会飞与不会飞的。前置条件更宽松、后置条件更严格，比如父类返回Map，子类返回HashMap；父类接受HashMap形参，子类接受Map。</p><h1 id="3-依赖倒转原则（Dependence-Inversion-Principle）"><a href="#3-依赖倒转原则（Dependence-Inversion-Principle）" class="headerlink" title="3 依赖倒转原则（Dependence Inversion Principle）"></a>3 依赖倒转原则（Dependence Inversion Principle）</h1><p>目的：避免需求变化导致过多的维护工作</p><p>含义：高层模块不应该依赖低层模块，二者都应该依赖其抽象；抽象不应该依赖细节；细节应该依赖抽象。</p><p>解决：面向接口编程，使用接口或者抽象类制定好规范和契约，而不去涉及任何具体的操作，把展现细节的任务交给他们的实现类去完成。</p><p>实例：母亲类Mother有讲故事方法TellStory，依赖一个Book类输入，并使用了Book类的getContent方法以便讲故事。那么下次需要母亲讲报纸上的故事、手机上的故事时，原有接口无能为力。这时，抽象一个包含getContent方法的IReader基类，Book、Newspaper、Cellphone各自实现。母亲的TellStory方法接受一个IReader实例，并调用getContent方法即可。</p><h1 id="4-接口隔离原则（Interface-Segregation-Principle）"><a href="#4-接口隔离原则（Interface-Segregation-Principle）" class="headerlink" title="4 接口隔离原则（Interface Segregation Principle）"></a>4 接口隔离原则（Interface Segregation Principle）</h1><p>目的：避免接口过于臃肿</p><p>含义：客户端不应该依赖它不需要的接口，一个类对另一个类的依赖应该建立在最小的接口上。</p><p>解决：适度细化接口，将臃肿的接口拆分为独立的几个接口。</p><p>实例：考试接口，包含考语数外、理化生、政史地等方法。学生类，实现考试接口，参加考试。文科生类、理科生类派生自学生类，实现考试接口时，就都需要实现一些自己不需要的方法（因为文科生不考理化生、理科生不考政史地）。这时，需要对考试接口进行细化，分为基础科考试接口、文科考试接口和理科考试接口；学生类实现基础科考试接口；文科生、理科生另外各自实现文科考试接口、理科考试接口。</p><h1 id="5-迪米特法则（Demeter-Principle）"><a href="#5-迪米特法则（Demeter-Principle）" class="headerlink" title="5 迪米特法则（Demeter Principle）"></a>5 迪米特法则（Demeter Principle）</h1><p>目的：降低类与类之间的耦合</p><p>含义：每一个软件单位对其他的单位都只有最少的知识，而且局限于那些与本单位密切相关的软件单位。</p><p>解决：不发生依赖、关联、组合、聚合等耦合关系的陌生类不要作为局部变量的形式出现在类的内部。</p><p>实例：校长管理老师，老师管理学生。校长需要全体点名时，首先对老师点名，但是不必通过老师获取学生的信息并点名，而应该让老师对各自管理学生的点名，否则校长和学生之间就发生了原本不必要的耦合，这样当学生类发生变化时，既要修改老师类，也要修改校长类。</p><h1 id="6-合成复用原则（Composite-Reuse-Principle）"><a href="#6-合成复用原则（Composite-Reuse-Principle）" class="headerlink" title="6 合成复用原则（Composite Reuse Principle）"></a>6 合成复用原则（Composite Reuse Principle）</h1><p>目的：防止类的体系庞大</p><p>含义：当要扩展类的功能时，优先考虑使用合成/聚合，而不是继承。</p><p>解决：当类与类之间的关系是”Is-A”时，用继承；当类与类之间的关系是”Has-A”时，用组合。</p><p>实例：如桥接模式，抽象和实现可以独立的变化，扩展功能时，增加实现类即可；比如装饰模式，只需要一个类，即可为一类类扩展新功能。对于显示图形需求，用图形Shape类，和显示Paint类实现。每个Shape类有一个Paint类指针负责图形绘制显示。Paint类派生RedPaint类和BluePaint类，传递给Shape类，实现图形不同颜色绘制，这样图形绘制逻辑和图形绘制实现可独立变化。某天增加需求，所有的绘制需要加边框，可增加PaintDecorator类，派生自Paint基类，每一个PaintDecorator类有一个Paint对象指针，增加虚函数AddedPaint，重写Paint的绘制方法，增加AddedPaint方法的调用。增加BorderPaintDecorator类，派生自PaintDecorator类，重写AddedPaint方法，增加添加绘制边框代码。这样新增加一个类可以对原始所有画笔类的功能进行扩充。</p><h1 id="7-开闭原则（Open-Close-Principle）"><a href="#7-开闭原则（Open-Close-Principle）" class="headerlink" title="7 开闭原则（Open Close Principle）"></a>7 开闭原则（Open Close Principle）</h1><p>目的：提高扩展性、便于维护</p><p>含义：对扩展开放，对修改封闭。即系统进行扩展是被鼓励的，对现有系统代码进行修改是不被支持的。也就是说，当软件有新的需求变化的时候，只需要通过对软件框架进行扩展来适应新的需求，而不是对框架内部的代码进行修改。</p><p>解决：设计模式前面6大原则以及23种设计模式遵循的好，开闭原则自然遵守的好。对需求的变更保持前瞻性和预见性，就可以使抽象具有更广泛适用性，设计出的软件架构就能相对稳定。软件需求中易变的细节，通过从抽象派生出实现类来扩展。</p><p>附：合成复用原则的实例代码，组合使用桥接模式和装饰模式</p><figure
