状态模式深度指南：构建可动态切换行为的艺术
状态模式深度指南：构建可动态切换行为的艺术 概述 状态模式（State Pattern）是一种行为型设计模式，它允许对象在内部状态改变时改变其行为。看起来对象似乎修改了其类。这种模式是解决复杂状态转换逻辑的利器，特别适合用于工作流引擎、游戏开发、订单处理系统等场景。 核心概念 状态模式的核心思想是：将每个状态封装为独立的类，对象的行为取决于其当前状态，而状态之间的转换由状态类自己管理。 关键角色 Context（上下文）：维护当前状态的实例，负责将请求委托给状态对象处理 State（抽象状态）：定义所有具体状态的共同接口 ConcreteState（具体状态）：实现各个具体状态的行为，并负责状态转换 为什么需要状态模式？ 传统方式的困境 想象一个订单系统，订单有多种状态：待支付、待发货、已发货、已完成、已取消。每个状态下可以执行不同的操作。 // 传统的if-else方式 class Order {…
