笔记：SpringBoot 工厂方法模式

工厂方法模式: 又称工厂模式，通过定义工厂父类负责定义创建对象的公共接口，而子类则负责生成具体的对象。
导致类个数过多

//鼠标产品
public interface Mouse {
    void printBrand();
}
//戴尔鼠标
public class DellMouse implements Mouse {
    @Override
    public void printBrand() {
        System.out.println("DELL MOUSE");
    }
}
//惠普鼠标
public class HpMouse implements Mouse {
    @Override
    public void printBrand() {
        System.out.println("HP MOUSE");
    }
}

//鼠标工厂接口
public interface MouseFactory {
    Mouse getMouse();
}
//戴尔鼠标工厂
public class DellMouseFactory implements MouseFactory {
    @Override
    public Mouse getMouse() {
        return new DellMouse();
    }
}
//惠普鼠标工厂
public class HpMouseFactory implements MouseFactory {
    @Override
    public Mouse getMouse() {
        return new HpMouse();
    }
}

//测试
@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class);
        MouseFactory mouseFactory = new HpMouseFactory();
        mouseFactory.getMouse().printBrand();
    }
}
