public static void main(String[] args) {
        SqlSession session = sqlSessionFactory.openSession();
        try {
            IUserOperation userOperation=session.getMapper(IUserOperation.class);
            User user = userOperation.selectUserByID(1);
            System.out.println(user.getUserAddress());
            System.out.println(user.getUserName());
