?测试方法：

System.out.println("加载Spring配置文件");//Resource res = new ClassPathResource("com/myspring/demo-bean.xml");//spring url require the src as initsource//BeanFactory factory = new XmlBeanFactory(res);ApplicationContext context = new ClassPathXmlApplicationContext("com/myspring/DatabaseXMLBean.xml");BeanFactory xmlbf = context;//ApplicationContext可以转换为BeanfactorySystem.out.println("加载spring配置文件结束");MyJavaBean bean = (MyJavaBean) context.getBean("column2");System.out.println("获取属性name："+bean.getName());??
