抽象工厂模式(abstract factory pattern) 详解

抽象工厂模式: 提供一个接口, 用于创建相关或依赖对象的家族, 而不需要明确指定具体类.

全部代码: http://download.csdn.net/detail/u012515223/7403553

具体方法:

1. 提供一个抽象工厂(abstract factory)接口(interface)类, 不同的具体工厂(concrete factory)继承此类.

代码:

/**
 * @time 2014年5月26日
 */
package factory;  

/**
 * @author C.L.Wang
 *
 */
public interface PizzaIngredientFactory {
    public Dough createDough();
    public Sauce createSauce();
    public Cheese createCheese();
    public Veggies[] createVeggies();
    public Pepperoni createPepperoni();
    public Clams createClam();
}

2. 具体工厂(concrete factory), 实现抽象工厂(abstract factory)接口(interface).

代码:

/**
 * @time 2014年5月26日
 */
package factory;  

/**
 * @author C.L.Wang
 *
 */
public class NYPizzaIngredientFactory implements PizzaIngredientFactory {  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createDough()
     */
    @Override
    public Dough createDough() {
        // TODO Auto-generated method stub
        return new ThinCrustDough();
    }  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createSauce()
     */
    @Override
    public Sauce createSauce() {
        // TODO Auto-generated method stub
        return new MarinaraSauce();
    }  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createCheese()
     */
    @Override
    public Cheese createCheese() {
        // TODO Auto-generated method stub
        return new ReggianoCheese();
    }  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createVeggies()
     */
    @Override
    public Veggies[] createVeggies() {
        // TODO Auto-generated method stub
        Veggies veggies[] = {new Garlic(), new Onion(), new Mushroom(), new RedPepper()};
        return veggies;
    }  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createPepperoni()
     */
    @Override
    public Pepperoni createPepperoni() {
        // TODO Auto-generated method stub
        return new SlicedPepperoni();
    }  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createClam()
     */
    @Override
    public Clams createClam() {
        // TODO Auto-generated method stub
        return new FreshClams();
    }  

}  

/**
 * @time 2014年5月26日
 */
package factory;  

/**
 * @author C.L.Wang
 *
 */
public class ChicagoPizzaIngredientFactory implements PizzaIngredientFactory {  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createDough()
     */
    @Override
    public Dough createDough() {
        // TODO Auto-generated method stub
        return new ThickCrustDough();
    }  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createSauce()
     */
    @Override
    public Sauce createSauce() {
        // TODO Auto-generated method stub
        return new PlumTomatoSauce();
    }  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createCheese()
     */
    @Override
    public Cheese createCheese() {
        // TODO Auto-generated method stub
        return new MozzarellaCheese();
    }  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createVeggies()
     */
    @Override
    public Veggies[] createVeggies() {
        // TODO Auto-generated method stub
        Veggies veggies[] = {new BlackOlives(), new Spinach(), new Eggplant()};
        return veggies;
    }  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createPepperoni()
     */
    @Override
    public Pepperoni createPepperoni() {
        // TODO Auto-generated method stub
        return new SlicedPepperoni();
    }  

    /* (non-Javadoc)
     * @see factory.PizzaIngredientFactory#createClam()
     */
    @Override
    public Clams createClam() {
        // TODO Auto-generated method stub
        return new FrozenClams();
    }  

}

3. 产品抽象(abstract)父类, 提供接口, 供具体产品(concrete product)调用.

代码:

/**
 * @time 2014年5月26日
 */
package factory;  

/**
 * @author C.L.Wang
 *
 */
public abstract class Pizza {
    String name;
    Dough dough; //生面团
    Sauce sauce; //调味汁
    Veggies veggies[];
    Cheese cheese;
    Pepperoni pepperoni;
    Clams clam;  

    abstract void prepare();  

    void bake() {
        System.out.println("Bake for 25 minutes at 350");
    }  

    void cut() {
        System.out.println("Cutting the pizza into diagonal slices");
    }  

    void box() {
        System.out.println("Place pizza in official PizzaStore box");
    }  

    void setName(String name) {
        this.name = name;
    }  

    public String getName() {
        return name;
    }
}

4. 具体产品(concrete product)继承产品抽象(abstract)父类, 使用工厂类实现继承接口, 通过不同的工厂生产不同的产品;
