我有这个代码： <li class="page-item" th:classappend="${currentPage == 0} ? 'disabled' : ''"> <a class="page-link" th:href="${currentPage == 0} ? '#' : @{/transits/page/{pageNum}(pageNum=${currentPage - 1})}" aria-label="Previous"> <span aria-hidden="true">«</span> </a> </li> 但是我有一个错误： 您可以在url语法的最底部所示，以两个步骤进行操作：https：//www.thymeleaf.org/doc/doc/articles/standardurlsictax.html 相关的例子是 <div th:with="baseUrl=(${user.admin}? '/admin/home' : ${user.homeUrl})"> ... <a th:href="@{${baseUrl}(id=${order.id})}">...</a> ... </div> 相似，您可以使用 <div th:with="baseUrl=(${currentPage == 0} ? '#' : '/transits/page/{pageNum}')"> ... <a th:href="@{${baseUrl}(pageNum=${currentPage - 1})}">...</a> ... </div>

我正在在我的项目中遇到与使用jmeter的性能测量有关的问题，我需要在其中使用OpenFeign。一段时间后（大约15秒）启动基准测试时，我会收到某些请求的例外。
有人可以帮助我解决这个问题吗？我非常感谢最简单的解决方案，不需要在OS级别修改TCP Time_Wait设置。
