Hello, world of design! 你好,设计模式的世界!

欢迎来到这里,很高兴你能拿到这本书,如果你能坚持看完并按照书中的例子进行实践,那么在编程开发的世界里,就又多了一个可以写出良好代码的人,同时也为架构师培养储备了一个人才。

可能在此之前你也多少了解过设计模式,但在实际的业务开发中使用却不多,多数时候都是大面积堆积ifelse组装业务流程,对于一次次的需求迭代和逻辑补充,只能东拼西凑Ctrl+CCtrl+V

所以为了能让更多的程序员👨‍💻‍更好的接受设计思想和架构思维,并能运用到实际的业务场景。本书的作者小傅哥,投入50天时间,从互联网实际业务开发中抽离出,交易、营销、秒杀、中间件、源码等22个真实场景,来学习设计模式实践使用的应用可上手技能。

谁发明了设计模式?

设计模式的概念最早是由 克里斯托佛·亚历山大 在其著作 《建筑模式语言》 中首次提出的。 本书介绍了城市设计的 “语言”,提供了253个描述城镇、邻里、住宅、花园、房间及西部构造的模式, 而此类 “语言” 的基本单元就是模式。后来,埃里希·伽玛约翰·弗利赛德斯拉尔夫·约翰逊理查德·赫尔姆 这四位作者接受了模式的概念。 1994 年, 他们出版了 《设计模式: 可复用面向对象软件的基础》 一书, 将设计模式的概念应用到程序开发领域中。

其实有一部分人并没有仔细阅读过设计模式的相关书籍和资料,但依旧可以编写出优秀的代码。这主要是由于在经过众多项目的锤炼和对程序设计的不断追求,从而在多年编程历程上提炼出来的心得体会。而这份经验最终会与设计模式提到的内容几乎一致,同样会要求高内聚、低耦合、可扩展、可复用。你可能也遇到类似的经历,在学习一些框架的源码时,发现它里的某些设计和你在做开发时一样。

我怎么学不会设计模式?

钱也花了,书也买了。代码还是一坨一坨的!设计模式是由多年的经验提炼出来开发指导思想。就像我告诉你自行车怎么骑、汽车怎么开,但只要你没跑过几千公里,你能记住的只是理论,想上道依旧很慌!

所以,本设计模式专题系列开始,会带着你使用设计模式的思想去优化代码。从而学习设计模式的心得并融入给自己。当然这里还需要多加练习,一定是人车合一,才能站在设计模式的基础上构建出更加合理的代码。

阅读建议

本书属于实战型而不是理论介绍类书籍,每一章节都有对应的完整代码,学习的过程需要参考书中的章节与代码一起学习,同时在学习的过程中需要了解并运行代码。学习完成后进行知识点的总结,以及思考🤔这样的设计模式在自己的业务场景中需要如何使用。

创建型模式

结构型模式

行为模式


截止到此设计模式内容就全部讲完了,可能书中会因作者水平有限,有一些描述不准确或者错字内容。欢迎提交给我,也欢迎和我讨论相关的技术内容,作者小傅哥,非常愿意与同好进行交流,互相提升技术。
