package spring.noautowiring.mode;



import org.springframework.beans.factory.BeanFactory;

import org.springframework.context.support.ClassPathXmlApplicationContext;



public class AutowireMain {

  public static void main(String[] args) {

    BeanFactory beanfactory = new ClassPathXmlApplicationContext(

        "context.xml");

    College coll = (College) beanfactory.getBean("college");

    System.out.println(coll);

  }

}
