我认为您需要检查一些您作为开发人员遇到过的问题，当您因为另一个设计更改而不得不第十次修改代码时，您会感到非常紧张。你可能有一个项目清单，你觉得有很多返工和痛苦。

From that list you can derive the scenarios that the Design Patterns intend to solve. Has there been a time where you needed to perform the same series of actions on different sets of data? Will you need to be able to future capability to an application but want to avoid reworking all your logic for existing classes? Start with those scenarios and return to the catalog of patterns and their respective problems they are supposed to solve. You are likely to see some matches between the GoF and your library of projects.

最好的方法就是用它们开始编码。设计模式是一个伟大的概念，仅仅通过阅读很难应用它们。从网上找到一些示例实现，然后围绕它们进行构建。

数据和对象工厂页面是一个很好的资源。他们会讲解这些模式，并给出概念上和现实世界中的例子。他们的参考资料也很棒。

我不知道哪本书最好，但纯粹主义者可能会说《设计模式:可重用面向对象软件的元素》

至于我个人最喜欢的，我喜欢O'Reilly出版的Head First Design Patterns。它是用对话的口吻写的，很吸引我。当我阅读它时，我同时检查了我的源代码，看看它是否适用于我所阅读的内容。如果有，我就重构。我就是这样学会责任链的。

练习-练习-练习。

I would think it is also difficult to study design patterns. You have to know more about OOP and some experiences with medium to big application development. For me, I study as a group of developers to make discussion. We follow A Learning Guide To Design Patterns that they have completed the patterns study. There are C# and JavaScript developers join together. It is fancy thing for me is the C# developer write codes in JavaScript and the JavaScript developer do the same thing for C# codes. After I leave a meeting I also research and read a few books at home to review. The better way to understand more and remember in my mind is to do blogging with examples in both C# and JavaScript in here http://tech.wowkhmer.com/category/Design-Patterns.aspx.

我建议首先在去了解每个设计模式之前请先了解模式的名称。此外，如果有人知道这个概念，请解释并给出一个例子，不仅是编程，而且是阅读世界。

例如:

工厂方法:

阅读世界:我只要给钱5美元、10美元或20美元，它就会生产出披萨，而不知道它是如何生产的，我只会得到一个小的、中等的或大的披萨，这取决于我投入的钱，这样我就可以吃或做任何事情。

编程:客户端只需将参数值$5，$10或$20传递给factory方法，它将返回Pizza对象。因此客户端可以使用该对象，而不知道它是如何处理的。

我不确定这能帮到你。这取决于与会者的知识水平。

The way I learned design patterns is by writing lots of really terrible software. When I was about 12, I have no idea what was good or bad. I just wrote piles of spaghetti code. Over the next 10 years or so, I learned from my mistakes. I discovered what worked and what didn't. I independently invented most of the common design patterns, so when I first heard what design patterns were, I was very excited to learn about them, then very disappointed that it was just a collection of names for things that I already knew intuitively. (that joke about teaching yourself C++ in 10 years isn't actually a joke)

这个故事的寓意是:编写大量的代码。就像别人说的，练习，练习，再练习。我认为，在您了解当前的设计为什么不好并寻找更好的方法之前，您不会很好地了解在哪里应用各种设计模式。设计模式书应该为您提供完善的解决方案和与其他开发人员讨论的通用术语，而不是对您不理解的问题的粘贴解决方案。

你试过《四人帮》这本书吗?
