# 适配器模式(Adapter)
适配器(Adapter)模式:将一个类的接口转换成客户希望的另外一个接口,使得原本由于接口不兼容而不能一起工作的那些类能一起工作。
> 适配器模式分为类结构型模式和对象结构型模式两种,前者类之间的耦合度比后者高,且要求程序员了解现有组件库中的相关组件的内部结构,所以应用相对较少些。
**该模式的主要优点如下。**
- 客户端通过适配器可以透明地调用目标接口。
- 复用了现存的类,程序员不需要修改原有代码而重用现有的适配者类。
- 将目标类和适配者类解耦,解决了目标类和适配者类接口不一致的问题。
**其缺点是:**
对类适配器来说,更换适配器的实现过程比较复杂。
应用场景:老代码接口不适应新的接口需求,或者代码很多很乱不便于继续修改,或者使用第三方类库。
想使用一个已存在的类,但是该类不符合接口需求;或者需要创建一个可重用的类,适配没有提供合适接口的其它类。
一句话总结:不改变原有类的情况下对其进行改造
## **①第一种方式:对象适配器**

> **注意点**:
> 这里的新接口使用了组合方式,UserInfo内部有一个成员变量保存老接口User对象,模块之间是松耦合的,这种结构其实就是组合模式。不要使用继承,虽然UserInfo继承User也能达到同样的目的,但是耦合度高,相互产生影响。
新能源汽车的发动机有电能发动机(Electric Motor)和光能发动机(Optical Motor)等,各种发动机的驱动方法不同,例如,电能发动机的驱动方法 electricDrive() 是用电能驱动,而光能发动机的驱动方法 opticalDrive() 是用光能驱动,它们是适配器模式中被访问的适配者。
客户端希望用统一的发动机驱动方法 drive() 访问这两种发动机,所以必须定义一个统一的目标接口 Motor,然后再定义电能适配器(Electric Adapter)和光能适配器(Optical Adapter)去适配这两种发动机
