Spring代码总结

1、配置方法获取对象

// 实例化Spring容器示例

        String conf = "applicationContext.xml";

        ApplicationContext ac = new ClassPathXmlApplicationContext(conf);



        // 利用Sprig调用构造器GregorianCalendar创建Calendar实例。

//        Calendar cal1 = (Calendar) ac.getBean("calendarObj1");

        Calendar cal1=ac.getBean("calendarObj1", Calendar.class);

        System.out.println("cal1:"+cal1);

2、关闭Spring容器

        // 关闭Spring容器，注意AbstractApplicationContext类型定义了close()方法

        AbstractApplicationContext ctx = (AbstractApplicationContext) ac;

        ctx.close();
