I have a MVC application based on spring-boot:2.5.4.
After migrating from spring-boot 2.5.4, to 2.5.14-2.6.7 Thymeleaf layout does'nt import header (header tag is empty) and leaves blank other inserted elements( like layouts/sidebar :: sidebar, layouts/footer :: footer) from the decorator.
I have upgraded my libs to:
<dependency>
<groupId>nz.net.ultraq.thymeleaf</groupId>
<artifactId>thymeleaf-layout-dialect</artifactId>
<version>3.1.0</version>
</dependency>
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity5</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
Main layout:
<!DOCTYPE html>
<html xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<head>
<!-- JS/ CSS-->
</head>
<body id="page-top">
<div th:replace="layouts/sidebar :: sidebar"></div>
<div id="content-wrapper" class="d-flex flex-column">
<div id="content">
<div layout:fragment="content"></div>
</div>
<footer class="sticky-footer bg-white">
<div th:replace="layouts/footer :: footer">
</div>
</footer>
</div>
</div>
and Page uwing this layout:
<!DOCTYPE html>
<html xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
layout:decorator="layouts/base_layout"
xmlns:th="http://www.thymeleaf.org">
<body>
<section layout:fragment="content">
some content
</section>
</body>
</html>
Has there been a change in spring-boot thymeleaf compability? When I define header a sa fragment, I can import header to the pages, but this is missing the point of having a layout class, when I have to import every element manually.
