文字模式的胸腺布局方言

Question

我正在尝试使用Thymeleaf和布局方言来设置html和文本模板处理：

@Configuration
public class ThymeleafConfiguration  {

@Bean
public TemplateEngine emailTemplateEngine() {
    final SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addTemplateResolver(textTemplateResolver());
    templateEngine.addTemplateResolver(htmlTemplateResolver());

    LayoutDialect dialect = new LayoutDialect();
    templateEngine.addDialect(dialect);

    return templateEngine;
}

private ITemplateResolver textTemplateResolver() {
    final ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
    templateResolver.setOrder(Integer.valueOf(1));
    templateResolver.setResolvablePatterns(Collections.singleton("text/*"));
    templateResolver.setPrefix("static/common/templates/email/");
    templateResolver.setSuffix(".txt");
    templateResolver.setTemplateMode(TemplateMode.TEXT);
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setCacheable(true);
    return templateResolver;
}

private ITemplateResolver htmlTemplateResolver() {
    ...
  }
}

HTML模板可以很好地与层次结构配合使用，但不能与文本模板配合使用

main.txt：

Title    

[#th:block layout:fragment="content"]
content
[/th:block]

Footer

content.txt：

[#th:block layout:decorate="~{text/main}"]
 [#th:block layout:fragment="content"]
   Here is the URL for password change:
   Some url...
 [/th:block]
[/th:block]

结果只是内容部分，而没有标题和页脚部分：

Here is the URL for password change:
Some url...

该方言是否应该以文本模式工作？
