1.工厂模式就是指隐藏创建类的细节，通过一个额外的工厂类来组织创建我们需要的对象，工厂按表现形式又分为静态工厂和工厂实例

2.   src/main/java/com/imooc/spring/ioc/factory/AppleStaticFactory.java 苹果的静态工厂

package com.imooc.spring.ioc.factory;

import com.imooc.spring.ioc.entity.Apple;

/**
 * 静态工厂通过静态方法创建对象，隐藏对象细节
 */
public class AppleStaticFactory
{
    public static Apple createSweetApple()
    {
        Apple apple = new Apple();
        apple.setTitle("红富士");
        apple.setOrigin("欧洲");
        apple.setColor("红色");
        return apple;
    }
}

2.1.  src/main/resources/applicationContext.xml

    <!--利用静态工厂获取对象-->
    <bean id="apple4" class="com.imooc.spring.ioc.factory.AppleStaticFactory" factory-method="createSweetApple"/>
