一、在spring快速入门（三）的基础上，我们来了解BeanFactory及配置。

　　Client

package com.murong.client; import org.springframework.beans.factory.BeanFactory; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.murong.action.UserAction; import com.murong.action.UserActionImpl; public class Client { public static void main(String[] args) { BeanFactory bf = new ClassPathXmlApplicationContext("applicationContext.xml"); UserAction userAction = (UserAction) bf.getBean("userActionImpl"); userAction.addUser("久伴",24); } }

 

　　首先BeanFactory是一个接口 ，有不同的实现类、当然还有其他的实现类，比如　　ApplicationContext

package com.murong.client; import org.springframework.beans.factory.BeanFactory; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.murong.action.UserAction; import com.murong.action.UserActionImpl; public class Client { public static void main(String[] args) { /*BeanFactory bf = new ClassPathXmlApplicationContext("applicationContext.xml");*/ ApplicationContext bf = new ClassPathXmlApplicationContext("applicationContext.xml"); UserAction userAction = (UserAction) bf.getBean("userActionImpl"); userAction.addUser("久伴",24); } }
