您的命名空间不正确。您可能需要添加百里香&springsecurity5如下所示：
<!DOCTYPE HTML>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity5">
<!-- head, body, etc -->
</html>
尝试使用！isAuthenticated((。像这样编辑你的代码：
<ul class="nav navbar-nav navbar-right">
<li><a href="#">SHOPPING CART</a></li>
<li><a sec:authorize="!isAuthenticated()" th:href="@{/login}">MY ACCOUNT</a></li>
<li><a sec:authorize="isAuthenticated()" th:href="@{/myProfile}">MY ACCOUNT</a></li>
<li><a sec:authorize="isAuthenticated()" th:href="@{/logout}">LOGOUT</a></li>
</ul>
