【Spring教程】框架搭建和基本配置

 加载classpath：
        new ClassPathXmlApplicationContext("beans.xml");
 加载磁盘路径：
        new FileSystemXmlApplicationContext("beans.xml");

ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
或者
BeanFactory context = new ClassPathXmlApplicationContext("beans.xml");

Student st= (Student)context .getBean("student");
或者
Student st= context.getBean(Student.class);

System.out.println("编号："+student.getId()); //编号：1
System.out.println("姓名："+student.getName()); //姓名：wang
System.out.println("年龄："+student.getAge()); //年龄：20
