DreamTiger的夢幻樂園

1、HelloApp
書上是：
BeanFactory factory = new XmlBeanFactory(new FileInputStream("hello.xml"));
應該是：
BeanFactory factory = new XmlBeanFactory(new FileSystemResource("hello.xml"));

2、KnightApp
在實現了XML中Minstrel的interceptor后，
需要把
KnightOfTheRoundTable knight = (KnightOfTheRoundTable) factory.getBean("knight");
改成：
Knight knight = (Knight) factory.getBean("knight");
否則會報：
Exception in thread "main" java.lang.ClassCastException: $Proxy0
