在讀spring in aciton 時，他用的BeanFactory factory = new XmlBeanFactory(new FileInputStream("hello.xml"));
可是現(xiàn)在的用的1.2.6版本的構造器(XmlBeanFactory)只能接收Resource接口了，所以調(diào)不出來是正常的事情，假設現(xiàn)在有一個文件hello.xml
讀取方法

1:ApplicationContext cx=new FileSystemXmlApplicationContext("hello.xml");//指定的路徑去找文件
2:ApplicationContext factory = new ClassPathXmlApplicationContext("hello.xml");//還會在classpath去找
3:Resource fa = new FileSystemResource("hello.xml");
? ?BeanFactory factory=new XmlBeanFactory(fa);
4:這個要設制classpath了，麻煩
　?Resource res = new ClassPathResource("com/springinaction/chapter01/hello/hello.xml");
　?BeanFactory factory=new XmlBeanFactory(res);
好了，用了上面那種方法都可以調(diào)用getBean("your bean name")了，
eg:?BeanFactory factory=new XmlBeanFactory(fa);
????? hello he=(hello)factory.getBean("hello");
????????????? he.getHello();
