【问题描述】：
错误指向这一行：
Caused by: org.attoparser.ParseException: Exception evaluating SpringEL expression: "#numbers.sequence( pageNumber + 1, patientsPage.totalPages > 10 + pageNumber ? pageNumber + 10 : patientsPage.totalPages, 1)"
这个表达有什么问题？这不是求和的正确方法吗？
这是我的代码：
<li class="page-item"
th:classappend="${i eq pageNumber + 1} ? 'active'"
th:each="i : ${#numbers.sequence( pageNumber + 1, patientsPage.totalPages > 10 + pageNumber ? pageNumber + 10 : patientsPage.totalPages, 1)}">
<a class="page-link" th:text="${i}"
th:title="${'Page '+ i}" rel="tooltip"></a>
</li>
