我使用 spring-boot-starter-thymeleaf 包将 Spring Boot Starter Parent 从 1.3.3.RELEASE 升级到当前的 2.0.4.RELEASE。升级后，属性布局：装饰器不再起作用。该属性不会被解析，而是包含在未解析的情况下，例如

Spring Boot Starter Parent 2.0.4.RELEASE 中是否有更多关于方言的要求？
更新： 似乎软件包 nz.net.ultraq.thymeleaf.LayoutDialect 没有通过 spring-boot-starter-thymeleaf 添加到类路径中？但是当我添加：
<dependency>
<groupId>nz.net.ultraq.thymeleaf</groupId>
<artifactId>thymeleaf-layout-dialect</artifactId>
<version>2.3.0</version>
</dependency>
到它加载的 POM
