Spring如何使用xml创建bean对象

 public static void main(String[] args) {  
  //1.使用 ApplicationContext 接口，就是在获取 spring 容器 
  ApplicationContext ac = new ClassPathXmlApplicationContext("bean.xml");  
  //2.根据 bean 的 id 获取对象  
  IAccountService aService = (IAccountService) ac.getBean("accountService");  
  System.out.println(aService);  
  IAccountDao aDao = (IAccountDao) ac.getBean("accountDao");  
  System.out.println(aDao); 
 }
