class="content">基本概念命令模式：一种行为型设计模式，它将“请求”封装为对象，使发送请求的客户端与执行请求的接收者解耦。通过这种封装，可以让请求参数化、排队执行、记录日志或支持撤销操作。 核心结构 命令接口（Command）：定义执行命令的方法（如execute()）。 具体命令（Concrete Command）：实现命令接口，绑定接收者和具体操作。 接收者（Receiver）：执行命令的具体对象，知道如何完成命令对应的操作。 调用者（Invoker）：持有命令对象，通过调用命令的方法来触发请求。 客户端（Client）：创建具体命令并设置其接收者，将命令交给调用者。 示例说明场景：遥控器控制家电 命令接口 1234567// 命令接口interface Command { void execute(); // 执行命令 void undo(); // 撤销命令（可选）} 接收者：电灯 1234567891011class Light { void on() { System.o...</div></div></div><div class="recent-post-item"><div class="recent-post-info no-cover"><a class="article-title"

class="content">基本概念责任链模式：使多个对象都有机会处理请求，从而避免请求的发送者和接收者之间的耦合关系。将这些对象连成一条链，并沿着这条链传递请求，直到有一个对象处理它为止。 核心思想：请求沿着处理者链传递，每个处理者决定是处理请求还是将其传递给下一个处理者，形成一个灵活的请求处理机制。 核心结构 Handler（处理者接口）：定义处理请求的接口，包含设置下一个处理者和处理请求的方法 ConcreteHandler（具体处理者）：实现处理者接口，决定是否处理请求，若不能处理则传递给下一个处理者 Client（客户端）：创建处理链，并向链的起始端发送请求 示例说明场景：员工请假审批系统，不同级别领导处理不同天数的请假申请 组长：处理1天内的请假 部门经理：处理3天内的请假 总经理：处理7天内的请假 超过7天的请假不予批准 处理者接口 123456789101112public abstract class Approver { protected Approver nextApprover; // 下一个处理者 // 设置下一个处理者 publi...</div></div></div><div class="recent-post-item"><div

主题状态变化时，主动通知所有观察者 观察者无需知道其他观察者的存在，只关注主题更新 核心结构 主题（Subject）：定义观察者注册/移除方法，维护观察者列表，状态变化时通知观察者。 观察者（Observer）：定义更新接口，接收主题通知并作出响应。 具体主题（ConcreteSubject）：实现主题接口，维护具体状态，状态变化时通知观察者。 具体观察者（ConcreteObserver）：实现观察者接口，存储与主题相关的状态，响应通知。 示例说明场景：股票价格监控系统，当股票价格变化时，自动通知所有关注该股票的投资者 定义主题接口 123456789public interface Stock { void attach(Investor investor); // 注册观察者 void
