In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn‘t a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.（在软件工程领域，设计模式是一个通用的、可重复的解决方案对一个经常发生的问题在软件设计领域。设计模式不是可以转化为代码的最终设计。它是用于解决在众多场景下，某一类问题的一个描述或者模板。）
