Question

美好的一天，我刚刚创建了一个使用Spring-boot和thymeleaf的项目。我试图利用布局方言，以便利用其像平板和＃34;等瓷砖。我已经查找了这个问题，每个响应都建议我添加布局方言作为spring-boot配置文件。但是我在这方面的每一次尝试都失败了，最近的一次尝试来自这个链接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();
    }
}

但它始终以：

结果

"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Dialect布局而不会破坏太多的spring-boot自动配置设置。我的pom既有百里香 - 布局 - 方言，又有百里香的启动依赖。

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"/>

堆栈跟踪：

Answer 1

OK！所以我找到了解决方案。问题出现在视图解析器中的装饰器名称中。所以在welcomeHome.html中，原始的装饰器声明是：

＆＃13;

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"/>

＆＃13;

工作解决方案是：

＆＃13;

<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"/>

＆＃13;

不同之处在于省略了＆＃34; .html＆＃34;在layout.html的末尾。所以

布局：装饰=＆＃34;的layout.html＆＃34;

成为：

布局：装饰=＆＃34;布局＆＃34;

从我现在的理解，thymeleafautoconfiguration将后缀设置为.html。这意味着没有必要将它添加到装饰器的文件名中。

Answer 2

LayoutDialect已经自动配置，因此您不需要做任何事情。你确定＆＃34; templates / layout.html＆＃34;实际上是在类路径上？

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