最常见的7种面向对象设计原则如下表所示：
表1 7种常用的面向对象设计原则

设计原则名称
定 义
使用频率

单一职责原则
(Single Responsibility Principle, SRP)
一个类只负责一个功能领域中的相应职责
★★★★☆

开闭原则
(Open-Closed Principle, OCP)
软件实体应对扩展开放，而对修改关闭
★★★★★

里氏代换原则
(Liskov Substitution Principle, LSP)

所有引用基类对象的地方能够透明地使用其子类的对象
★★★★★

依赖倒转原则
(Dependence Inversion Principle, DIP)
抽象不应该依赖于细节，细节应该依赖于抽象
★★★★★

接口隔离原则
(Interface Segregation Principle, ISP)
使用多个专门的接口，而不使用单一的总接口
★★☆☆☆

合成复用原则
(Composite Reuse Principle, CRP)
尽量使用对象组合，而不是继承来达到复用的目的
★★★★☆

迪米特法则
(Law of Demeter, LoD)
一个软件实体应当尽可能少地与其他实体发生相互作用
★★★☆☆
