SOLID之依赖反转原则

依赖反转原则的英文翻译是 Dependency Inversion Principle，缩写为 DIP。中文翻译有时候也叫依赖倒置原则。

High-level modules shouldn’t depend on low-level modules. Both modules should depend on abstractions. In addition, abstractions shouldn’t depend on details. Details depend on abstractions.

高层模块不应该依赖低层模块，高层模块和低层模块都应通过抽象来互相依赖。抽象不要依赖具体的实现细节，具体的实现细节应该依赖抽象。
