방법	내용
1	import org.springframework.beans.factory.BeanFactory; import org.springframework.beans.factory.xml.XmlBeanFactory; import org.springframework.core.io.ClassPathResource; import org.springframework.core.io.Resource;
	Resource resource = new ClassPathResource("hg.xml"); BeanFactory factory = new XmlBeanFactory(resource);
2	import org.springframework.context.support.AbstractApplicationContext; import org.springframework.context.support.GenericXmlApplicationContext;
	AbstractApplicationContext factory = new GenericXmlApplicationContext("hg.xml");
3	import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext;
	ApplicationContext factory = new ClassPathXmlApplicationContext("hg.xml");
· hgImpl bean = factory.getBean("hg",hgImpl.class); => hgImpl : 인터페이스를 상속받는 클래스                                                                         "hg" : bean id / hglmpl.class : 인터페이스를 상속받는 클래스 · bean.sum( ); => hglmpl 클래스에 있는 sum 메서드 호출
