Spring3.0新特性（二）

2、context.getBean可以使用泛型，不用强制转换了

@Test
	public void testSave() {
		ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
		UserDAO userDAO = context.getBean("userDAO", UserDAO.class);
		
		//UserDAO userDAO = (UserDAO)context.getBean("userDAO");
		userDAO.save(new User());
	}
