Spring IOC容易模拟

Spring IOC简单模拟
spring框架的IOC

1.使用DOM4J读取xml配置文件

package com.dicmo.spring;import org.dom4j.DocumentException;public class Test {public static void main(String [] args) throws DocumentException, InstantiationException, IllegalAccessException, ClassNotFoundException{XMLPathApplicationContext context = new XMLPathApplicationContext("G:/myeclpse6.5/spring/src/com/dicmo/spring/applicationContext.xml");Spring spring = (Spring)context.getBean("spring");spring.say();Plane plane = (Plane)context.getBean("plane");plane.say();}}
