Spring 引导 Thymeleaf：无法从资源/模板下的子文件夹中选取模板

Question

I am using Thymeleaf v3.0.11.RELEASE Spring Boot v2.1.3.RELEASE, and I am facing issues with my templates placed under classpath:templates/folder1/folder2/.

I tried the below approaches

• Setting up the property spring.thymeleaf.prefix to classpath:/templates/**/ , classpath:/templates/* and other similar patterns

• Tried adding the template resolver in application startup class.

   @Bean public TemplateEngine emailTemplateEngine() { final SpringTemplateEngine templateEngine = new SpringTemplateEngine(); templateEngine.addTemplateResolver(htmlTemplateResolver()); return templateEngine; } private ITemplateResolver htmlTemplateResolver() { final ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver(); templateResolver.setResolvablePatterns(Collections.singleton("/*")); templateResolver.setTemplateMode(TemplateMode.HTML); templateResolver.setCharacterEncoding("UTF-8"); templateResolver.setCacheable(false); return templateResolver;

  }

These approaches aren't working and I am still getting error:

"Error resolving template [template_name], template might not exist or might not be accessible by any of the configured Template Resolvers"

Am I missing something? I just need to know the way to enable wildcards for the suffix.

Note: It works if I hard code classpath:templates/folder1/folder2 , but I can't since there are going to be multiple folders and I don't want to fixate all the folder names.

add the following configuration class in your app

@Configuration
public class ThymeleafConfig {

  @Bean
  public SpringTemplateEngine springTemplateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addTemplateResolver(htmlTemplateResolver());
    return templateEngine;
  }

  @Bean
  public SpringResourceTemplateResolver htmlTemplateResolver() {
    SpringResourceTemplateResolver templateResolver =
        new SpringResourceTemplateResolver();
    templateResolver.setPrefix("classpath:/templates/");
    templateResolver.setSuffix(".html");
    templateResolver.setTemplateMode(
        StandardTemplateModeHandlers.HTML5.getTemplateModeName());
    templateResolver.setCharacterEncoding(StandardCharsets.UTF_8.name());
    return templateResolver;
  }

}

Mine didn't work until I changed templateResolver.setPrefix("/WEB-INF/views/"); to templateResolver.setPrefix("/WEB-INF/templates/"); and renamed the views folder to templates .

I have no idea why but this is the way it is.
