Spring 在Thymeleaf'的前缀中使用通配符；s模板解析器

我正在尝试设置Thymeleaf，以便它在我的类路径中搜索所有子包以查找模板文件（例如

my.root.package.subpackage1

，

my.root.package.subpackage2

，

my.root.package.subpackage3

）

我的配置如下所示：

@Bean
public ThymeleafViewResolver viewResolver() {
    final ThymeleafViewResolver resolver = new ThymeleafViewResolver();
    resolver.setTemplateEngine(templateEngine());
    resolver.setCharacterEncoding("UTF-8");
    return resolver;
}

@Bean
public SpringTemplateEngine templateEngine() {
    final SpringTemplateEngine engine = new SpringTemplateEngine();
    engine.setTemplateResolver(templateResolver());
    return engine;
}

@Bean
public SpringResourceTemplateResolver templateResolver() {
    final SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
    resolver.setApplicationContext(context);
    resolver.setPrefix("classpath:my/root/package/**/");
    resolver.setSuffix(".html");
    resolver.setTemplateMode(TemplateMode.HTML);
    return resolver;
}

但这引发了一个例外：

Java.io.FileNotFoundException: class path resource [my/root/package/**/Example.html] cannot be opened because it does not exist
    org.springframework.core.io.ClassPathResource.getInputStream(ClassPathResource.java:172)

    org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:968)

    org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:107)

它似乎不喜欢通配符。如果我对子包进行硬编码，效果很好

你知道为什么这样不行吗
