Spring 读取XML配置文件的两种方式

import org.springframework.context.ApplicationContext;  
import org.springframework.context.support.ClassPathXmlApplicationContext;  
 
public class TestAction {  
 
 public static void main(String[] args) {  
  ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");  
  Action bean = (Action) ctx.getBean("theAction");  
  System.out.println(bean.execute("Rod"));  
 }  
}

这种方式的缺点是，

ClassPathXmlApplicationContext  构造函数中的参数不能是文件所在的绝对路径；

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.context.ApplicationContext;  
import org.springframework.context.support.ClassPathXmlApplicationContext;  
import org.springframework.core.io.FileSystemResource;
import org.springframework.core.io.Resource;
 
public class TestAction {  
 
 public static void main(String[] args) throws FileNotFoundException {
    Resource is = new FileSystemResource("E:\Users\panteng\Workspaces\MyEclipse 10\mySpring\src\applicationContext.xml");
    BeanFactory  factory = new XmlBeanFactory((Resource) is);
    Action bean = (Action) factory.getBean("theAction");
    System.out.println(bean.execute("Rod"));  
 }  
} 

这种方式可以弥补第一种方式的缺点，建议使用第二种！
