最近初学spring，在测试的时候发现这个问题，请问是什么原因呢？
//从spring容器中获得
String xmlPath = "/spring01/src/applicationContext.xml";
ApplicationContext applicationContext = new ClassPathXmlApplicationContext(xmlPath);
//1.获得容器
//2.获得内容-不需要自己new,都是从spring容器中获得
UserService uservice = (UserService)applicationContext.getBean("UserServicesId");
uservice.addUser();
报错为：
