8.工厂方法模式

一 典型工厂方法模式（Factory Method）结构图

二 典型工厂模式实现

测试代码 #include <iostream> using namespace std; class Product{ public: string name; virtual void show(){ cout << "我是:"; } }; class Desk : public Product { public: Desk(){ name = "桌子"; } void show(){ Product::show(); cout << name << endl; } }; class Cup : public Product { public: Cup(){ name = "杯子"; } void show(){ Product::show(); cout << name << endl; } }; class IFactory{ public: virtual Product* createProduct() = 0; }; class DeskFactory : public IFactory{ public: Product* createProduct(){ return new Desk(); } }; class CupFactory : public IFactory{ public: Product* createProduct(){ return new Cup(); } }; int main() { IFactory *ifactory = new DeskFactory(); Product *product = ifactory->createProduct(); product->show(); IFactory *ifactory_2 = new CupFactory(); Product *product_2 = ifactory_2->createProduct(); product_2->show(); return 0; }

测试结果：

我是:桌子 我是:杯子
