Question

我的索引文件的正文如下所示：

<div class="container" style="width: 100% !important;">

    <!--Header-->
    <div th:replace="fragments/header :: header"></div>

    <!--Content-->
    <!--<div th:replace="@{'fragments/' + ${template}} :: ${template}"></div>-->

    <!--Footer-->
    <div th:replace="fragments/footer :: footer"></div>

</div>

似乎在抱怨我的标题评论下的这一行，但我不确定为什么。会发生什么事？

这是我的错误：

There was an unexpected error (type=Internal Server Error, status=500).
Error resolving fragment: "~{'fragments/header' :: header}": template or fragment could not be resolved (template: "index" - line 34, col 10)

Answer 1

是否有带

的文件模板/ fragments / header.html

< ... th:fragment="header">

在classpath中？

Answer 2

我不确定你能做到这一点：

或者可以通过前缀和后缀加双下划线进行预处理。

即使被注释掉，Thymeleaf也会处理这条线。

无法在Springboot应用程序中检索模板
