SOLID 设计原则

• S: Single Responsibility 单一职责原则

Every class should have a single responsibility and that responsibility should be entirely met by that class

• O: Open/Closed 开闭原则

Open for extension but closed for modification; inheritance is used for this, e.g. through the use of inherited abstract base classes

• L: Liskov Substitution Principle 里氏替换原则

If S<:T (“S is a subtype of T”) then a T object can be replaced with an S object and no harm done

• I: Interface Segregation 接口隔离原则

Client code should not have to implement interfaces it doesn’t need

• D: Dependency Inversion 依赖倒置原则

High level, complex modules should not depend on low-level, simple models — use abstraction, and implementation details should depend on abstractions, not the other way around
