package com.javalec.ex;

import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.GenericXmlApplicationContext;

public class MainClass {
    public static void main(String[] args) {
        String configLocation = "classpath:applicationCTX.xml";
        AbstractApplicationContext ctx = new GenericXmlApplicationContext(configLocation);  // 스프링 컨테이너 생성(Ioc)
        MyInfo myInfo = ctx.getBean("myInfo", MyInfo.class); // 스프링 컨테이너에서 컴포넌트 가져옴
        myInfo.getInfo();
        ctx.close();
    }
}​
