Question

我正在使用thymeleaf作为引擎视图运行Springboot项目

我在控制器中为@ModelAttribute命令的PUT请求的参数传递外键时遇到问题：

<form th:action="@{/order/{clientid}/(clientid=${order.client.clientid}"th:method="put" action="put" th:object="${order}">

这里是我关注的链接：https://www.thymeleaf.org/doc/articles/standardurlsyntax.html

错误显示：

尝试添加)}：

<form th:action="@{/order/{clientid}/(clientid=${order.client.clientid})}" th:method="put" action="put" th:object="${order}">

您的表单标记不包含相同数量的(和)。 {和}也是如此。

Thymeleaf处理URL中的外键，用于PUT请求的操作
