spring多个配置文件的问题。。

　在一个工程个配置多个spring的配置文件，应该是没问题的。

　但在测试的时候，我是这样写的：

BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext_*.xml");
User user = (User)factory.getBean("user");
user.setName("lisi");
System.out.println(user.getName());

两个配置文件分别是：applicationContext_bean.xml和applicationContext_other.xml;

结果报个了错：

Exception in thread "main" java.lang.IllegalArgumentException: Resource path [D:/寮犺氨/spring_ioc/bin] does not denote a directory

然后，我把BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext_*.xml");里面的"*"给改成bean，因为上面有这个文件。。

他就不报错了，能正常输出！

这是为什么呢？？
