1、一、Spring入门体验小实例注意：用spring之前要将相应spring包导进来,然后bulidpath才能用spring来开发。Code:packagecom.service;publicclassByeService{privateStringname;publicStringgetName(){returnname;}publicvoidsetName(Stringname){this.name=name;}publicvoidsayBye(){System.out.println("Lilysaybyebyeto"+name);}}pack
2、agecom.service;publicclassUserService{privateStringname;privateByeServicebyService;publicByeServicegetByService(){returnbyService;}publicvoidsetByService(ByeServicebyService){this.byService=byService;}publicStringgetName(){returnname;}publicvoidsetName(Stringname){this.name=nam
3、e;}publicvoidsayHello(){System.out.println("Lily"+"sayhelloto"+name);byService.sayBye();}}packagecom.test;importorg.springframework.context.ApplicationContext;importorg.springframework.context.support.ClassPathXmlApplicationContext;importcom.service.UserService;publicclassTest{
4、publicstaticvoidmain(String[]args){//TODOAuto-generatedmethodstub//使用传统方法来调用UserService的sayHello方法6/*UserServiceuserService=newUserService();userService.setName("小丽");userService.sayHello();*///现在用spring来完成上面的任务//1.得到spring的applicationContext对象ApplicationContextac=newClassPathX
5、mlApplicationContext("applicationContext.xml");//从ac（代表容器applicationContext)中取得对应的beanUserServiceus=(UserService)ac.getBean("userService");us.sayHello();//从ac（代表容器applicationContext)中取得对应的bean/*ByeServicebyeService=(ByeService)ac.getBean("byeService");byeService.sayBye();*/}}XM
