annotation

종류가 굉장히 많다.

 

@Autowired

- 필요한 곳에 자동으로 묶기 => xml에 새로운 bean 필요 => main에 factory도 바꿔주어야함

<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"></bean>

	public static void main(String[] args) {
		
//		BeanFactory factory = 
//				new XmlBeanFactory(new FileSystemResource("src/app.xml"));
		
		ApplicationContext context = 
				new ClassPathXmlApplicationContext("app.xml");
		
		
		Greetingimple gr = context.getBean("gi", Greetingimple.class);
		

		gr.printMsg();
	}
