//Srping容器加载的三种方式
//第一种:ClassPathXmlApplicationContext ClassPath类路径加载:指的是classes路径
//ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
//第二种:文件系统路径获得配置文件【绝对路径】
// ApplicationContext ac = new FileSystemXmlApplicationContext("E:\\Spring-day01\\spring01\\src\\beans.xml");
//第三种:使用BeanFactory
String path = "E:\\Spring-day01\\spring01\\src\\beans.xml";
