Java Spring

Spring的IOC机制，利用了java的反射机制，通过读取配置文件，动态生成所需要的类。

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        Resource rs = new FileSystemResource("helloMessage.xml");
        BeanFactory bf = new XmlBeanFactory(rs);
        Person person = (Person)bf.getBean("person");
        String s = person.sayHello();
        System.out.println("The person is currently saying " + s);
        
    }
