Spring 读取XML配置文件的两种方式

时间：2022-05-09 01:35:35
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"));

 }

}

方式一

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"));

 }

}

方式二

这种方式可以弥补第一种方式的缺点，建议使用第二种！
