工厂模式

标准代码
1.先建立一个抽象工厂类

public abstract class AbstarctFactory {    public abstract <T extends AbstractProduct> T createProduct(Class<T> c);}

2.建立一个抽象产品类

public abstract class AbstractProduct {    //产品类的公共方法    public void method1(){        //业务逻辑处理    }    public abstract void method2();}

3.建立一个具体工厂类

public class FactoryRealize extends AbstarctFactory{    @Override    public <T extends AbstractProduct> T createProduct(Class<T> c) {        AbstractProduct product = null;        try {            product = (AbstractProduct) Class.forName(c.getName()).newInstance();} catch (InstantiationException e) {        e.printStackTrace();        } catch (IllegalAccessException e) {        e.printStackTrace();        } catch (ClassNotFoundException e) {        e.printStackTrace();        }        return (T) product;        }}

4.建立具体产品类

public class Product extends AbstractProduct {    @Override    public void method2() {    }}

5.模拟场景测试

public class Client {    public static void main(String[] args){        AbstarctFactory factoryRealize = new FactoryRealize();        AbstractProduct products = factoryRealize.createProduct(Product.class);        products.method2();    }}

注意：具体实际抽象模式的创建要具体实际需求去扩展
