spring-从spring工厂获取Bean的两种方法

先配置 applicationContext.xml

private IUserService userService; @Test public void testService() { ApplicationContext ca = new ClassPathXmlApplicationContext("applicationContext.xml"); //方式一【推荐】：通过id从工厂获取Bean userService = (IUserService) ca.getBean("userService"); //方式二：通过类型从工厂获取Bean userService = ca.getBean(IUserService.class); userService.testService(); } }
