Could not open ServletContext resource [/templates/show.xsl]

I have a spring-boot + thymeleaf application - so im basicly using no xml files for configuration. Classic html templates work fine for me, but i am having troubles with xsl. I followed this tutorial Spring MVC XstlView and XsltViewResolver Example but ended up with java.io.FileNotFoundException: Could not open ServletContext resource [/templates/show.xsl]

This is how my configuration class looks like

@Configuration
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter {

    private static final String[] CLASSPATH_RESOURCE_LOCATIONS = {
            "classpath:/META-INF/resources/", "classpath:/resources/",
            "classpath:/static/", "classpath:/public/" };

    @Bean
    @Description("Thymeleaf template resolver serving HTML 5")
    public ClassLoaderTemplateResolver htmlTemplateResolver() {
        ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();

        templateResolver.setPrefix("templates/");
        templateResolver.setCacheable(false);
        templateResolver.setSuffix(".html");
        templateResolver.setTemplateMode("HTML5");
        templateResolver.setCharacterEncoding("UTF-8");

        return templateResolver;
    }

    @Bean
    @Description("Thymeleaf template resolver serving XML")
    public ClassLoaderTemplateResolver xmlTemplateResolver() {
        ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();

        templateResolver.setPrefix("templates/");
        templateResolver.setCacheable(false);
        templateResolver.setSuffix(".xml");
        templateResolver.setTemplateMode("XML");
        templateResolver.setCharacterEncoding("UTF-8");

        return templateResolver;
    }

    @Bean
    @Description("Thymeleaf template engine with Spring integration")
    public SpringTemplateEngine templateEngine() {

        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.addTemplateResolver(htmlTemplateResolver());
        templateEngine.addTemplateResolver(xmlTemplateResolver());

        return templateEngine;
    }

    @Bean
    @Description("Thymeleaf view resolver")
    public ViewResolver viewResolver() {

        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();

        viewResolver.setTemplateEngine(templateEngine());
        viewResolver.setCharacterEncoding("UTF-8");

        return viewResolver;
    }

    @Bean
    public ViewResolver getXSLTViewResolver(){

        XsltViewResolver xsltViewResolver = new XsltViewResolver();
        xsltViewResolver.setOrder(1);
        xsltViewResolver.setSourceKey("xmlSource");

        xsltViewResolver.setViewClass(XsltView.class);
        xsltViewResolver.setViewNames(new String[] {"show"});
        xsltViewResolver.setPrefix("templates/");
        xsltViewResolver.setSuffix(".xsl");

        return xsltViewResolver;
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        if (!registry.hasMappingForPattern("/webjars/**")) {
            registry.addResourceHandler("/webjars/**").addResourceLocations(
                    "classpath:/META-INF/resources/webjars/");
        }
        if (!registry.hasMappingForPattern("/**")) {
            registry.addResourceHandler("/**").addResourceLocations(
                    CLASSPATH_RESOURCE_LOCATIONS);
        }
    }
}

From controller i am trying to redirect to my xsl template like this:

    @RequestMapping(value="/form", method=RequestMethod.POST, params="action=show")
public ModelAndView show(@ModelAttribute Team team) throws MarshalException {
    Source source = new StreamSource(new ByteArrayInputStream(xmlService.getXmlStream(team).toByteArray()));
    // adds the XML source file to the model so the XsltView can detect
    ModelAndView model = new ModelAndView("show");
    model.addObject("xmlSource", source);
    return model;
}

This is how my project files look like.

I would appreciate any suggestions how to make it work. Thank you
