何时使用哪种设计模式？ [英] When to use which design pattern?

问题描述

我非常喜欢设计模式，但是我很难看清我何时可以申请。我已经阅读了很多设计模式被解释的网站。我明白了他们中的大多数，但是我觉得很难在我自己的情况下认识到一种模式。

I like design patterns very much, but I find it difficult to see when I can apply one. I have read a lot of websites where design patterns are explained. I do understand the most of them, but I find it difficult to recognize a pattern in my own situations.

所以这就是为什么我问这个问题。在使用哪种设计模式时，是否有任何指引/闹钟。

So, that is why I ask this question. Are there any guidelines / alarm bells when to use which design pattern.

例如，如果您正在执行switch语句来确定需要创建哪个对象，那么您可能想要使用工厂的设计模式。因此，这种情况下的switch语句是使用Factory模式的闹钟。

For example, if you are doing a switch statement to determine which object you need to create, you probably want to use the factory design pattern. So the switch statement in this case is a 'alarm bell' to use the Factory pattern.

那么，你知道更多的闹钟来确定设计模式吗？

So, do you know more 'alarm bells' to determine a design pattern?

While Jeremy here deals with a few set of patterns, you must read these articles and then follow it up with this: http://codebetter.com/jeremymiller/2005/09/01/learning-about-design-patterns/

还可以使用本文的引用（特别是Eric Gamma的面试），你应该组。

Also use the references on this article(especially Eric Gamma's interview) and you should be set.
