package sam07;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class HelloApp {

	public static void main(String[] args) {						//원래는 resources 폴더에 다 가져다 놓는데 만일 다른폴더에 넣는다면 이렇게 하면된다.
		ApplicationContext ac = new ClassPathXmlApplicationContext("/sam07/bean07.xml");
		MessageBean mb = (MessageBean) ac.getBean("mb7");
		mb.sayHello();
	}
