表演接口Performer
[java]view plain copy packagecom.jCuckoo.demo;publicinterfacePerformer{voidperform()throwsException;}
定义魔术师Juggler，实现表演接口
[java]view plain copy packagecom.jCuckoo.demo;publicclassJugglerimplementsPerformer{privateintbeanBags=3;publicJuggler(){}publicJuggler(intbeanBags){this.beanBags=beanBags;}publicvoidperform()throwsException{System.out.println("表演开始：魔术师欺骗了"+beanBags+"个游戏豆。");}}
spring的配置文档applicationContext.xml

测试类，获取魔术师，并进行表演。
[java]view plain copy packagecom.jCuckoo.test;importorg.springframework.context.ApplicationContext;importorg.springframework.context.support.ClassPathXmlApplicationContext;importcom.jCuckoo.demo.Performer;publicclassMainTest{/***@paramargs*/publicstaticvoidmain(String[]args){ApplicationContextctx=newClassPathXmlApplicationContext("applicationContext.xml");Performerperformer=(Performer)ctx.getBean("juggler");try{performer.perform();}catch(Exceptione){e.printStackTrace();}}}
最终结果：
----开演之前，请占座---- ----开始之前，请关机---- oooooooo环绕通知开始oooooooo 表演开始：魔术师欺骗了3个游戏豆。 ****演出结束，可以开机**** ****鼓掌，继续鼓掌。**** oooooooo环绕通知结束oooooooo 演出耗时共计：1毫秒。
