estou tentando listar o banco de dados na index

so mudei pouca coisa relacionado ao curso @RequestMapping("/") public ModelAndView ListaProduto() {

ModelAndView mw = new ModelAndView("index"); List p = (List) mystore.findAll(); mw.addObject("produto",p); return mw; }

<tbody>
            <tr th:each="produto : ${produto}">

                <td><span th:text="${produto.P_VENUE}"></span></td>
                <td><span th:text="${produto.P_DATE}"></span></td>
                <td><span th:text="${produto.P_BASEPRODUCT}"></span></td>

            </tr>
        </tbody>
