//方式一：在CLASSPATH路径下获取XMLBeanFactory实例
ClassPathResource res = new ClassPathResource("container.xml");
XmlBeanFactory factory = new XmlBeanFactory(res);
HelloBean hellobean = (HelloBean)factory.getBean("helloBean");
hellobean.sayHelloWorld();

//方式二：指定绝对路径建ApplicatinContext实例
FileSystemXmlApplicationContext context = new FileSystemXmlApplicationContext("D:\\My_Struts_Cvs8\\springioc\\src\\container.xml");
BeanFactory factory2 = (BeanFactory) context;
HelloBean hellobean2 = (HelloBean)factory2.getBean("helloBean");
hellobean2.sayHelloWorld();

//方式三：通过ClassPathXmlApplicationContext创建BeanFactory实例
ClassPathXmlApplicationContext context3 = new ClassPathXmlApplicationContext("container.xml");
BeanFactory factory3 = (BeanFactory) context3;
HelloBean hellobean3 = (HelloBean)factory3.getBean("helloBean");
hellobean3.sayHelloWorld();
}
