【中文标题】升级的 Spring Boot Starter Parent - Thymeleaf 方言布局：装饰器坏了【英文标题】：Upgraded Spring Boot Starter Parent - Thymeleaf Dialect layout:decorator broke 【发布时间】：2019-01-23 08:30:53 【问题描述】：

我使用 spring-boot-starter-thymeleaf 包将 Spring Boot Starter Parent 从 1.3.3.RELEASE 升级到了当前的 2.0.4.RELEASE。升级后属性 layout:decorator 不再起作用。该属性未解析，而是包含未解析，例如

<!DOCTYPE html>
<html
xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
layout:decorate="layouts/admin.layout">
<head>
    <title>Admin</title>
</head>
<body>

pom.xml 包含在下面

Spring Boot Starter Parent 2.0.4.RELEASE 中是否对方言有更多要求？

【问题讨论】：

【参考方案1】：

更新：好像包 nz.net.ultraq.thymeleaf.LayoutDialect 没有通过 spring-boot-starter-thymeleaf 添加到类路径中？但是当我添加时：

<dependency>
<groupId>nz.net.ultraq.thymeleaf</groupId>
<artifactId>thymeleaf-layout-dialect</artifactId>
<version>2.3.0</version>
</dependency>

到它加载的 POM
