maven - 如何将布局方言添加到 spring-boot thymeleaf 自动配置文件中

美好的一天，我刚刚创建了一个使用 Spring-boot 和 thymeleaf 的项目。我正在尝试利用布局方言，以利用其“像模板一样的瓷砖”。我已经查找过这个问题，每个响应都建议我将布局方言添加为 spring-boot 配置文件。但我对此的每次尝试都失败了，最近一次来自此链接 How do I add a thymeleaf dialect to spring boot? 。所以我在配置文件中添加了这个

@Configuration
public class ThymleafConfiguration {
    @Bean
    public LayoutDialect layoutDialect() {
        return new LayoutDialect();
    }
}

但结果总是:

"Error resolving template "layout.html", template might not exist or might not be accessible by any of the configured Template Resolvers (welcomeHome:4)"

但是layout.html位于/resources/templates文件夹中，所以我知道它不是位置不匹配。我的目标只是添加布局 Dialect，而不破坏太多的 spring-boot 自动配置设置。我的 pom 同时具有 thymeleaf-layout-dialect 和 thymeleaf starter 依赖项。

欢迎首页.html

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
      layout:decorator="layout.html">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>

堆栈跟踪:

最佳答案

好的!所以我想出了解决办法。问题在于 View 解析器中的装饰器名称。所以在welcomeHome.html中原始的装饰器声明是: 

welcomeHome.html
    <html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
      layout:decorator="layout.html">
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>

工作解决方案是:

<html xmlns="http://www.w3.org/1999/xhtml"
 xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
  layout:decorator="layout">
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>

区别在于省略了layout.html末尾的“.html”。所以

布局:装饰器=“layout.html”

变成:

布局:装饰器=“布局”

据我现在了解，thymeleafautoconfiguration 将后缀设置为 .html。这意味着不需要将其添加到装饰器的文件名中。

关于maven - 如何将布局方言添加到 spring-boot thymeleaf 自动配置文件中，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27214584/
