    @Autowired
    UserDao userdao;

// userDao 인터페이스 구현한곳에서  인스턴스들 받아먹으려고
// userDao 객체도 안만들고 넘겨받아서 메서드나 인스턴스 사용할수있음

    @Test
    public void insertUser() throws Exception {
        userdao.deleteAll();
        User user = new User("TestHanReal", "1234", "ABC", "aaa@Aaaa.com", new Date(), "fb", new Date());

        int rowCnt = userdao.insertUser(user);

        //   User user2 = userdao.selectUser("TestHanReal");
        assertTrue(rowCnt == 1);
    }

 

root-context.xml 확인 해봐도 잘되있는거 같음
