Resource resource = new ClassPathResource("applicationContext.xml");

BeanFactory factory = new XmlBeanFactory(resource);

packageName.classname idName = new  packageName.classname();

className bean = (className)factory.getBean("idName"); //활용방법

className bean = (className)factory.getBean("a"); //활용방법

className bean = (className)factory.getBean("b"); //활용방법
