Can't load styles using pug4j template engine in spring boot

Question

I try to load style from my resources folder (/resources/static/styles.css) but embedded tomcat answers 404.

@Configuration
@EnableWebMvc
public class PugTemplateConfiguration {
    @Bean
    public SpringTemplateLoader templateLoader() {
        SpringTemplateLoader templateLoader
                = new SpringTemplateLoader();
        templateLoader.setTemplateLoaderPath("classpath:/templates/");
        templateLoader.setEncoding("UTF-8");
        templateLoader.setSuffix(".pug");
        return templateLoader;
    }
    @Bean
    public PugConfiguration pugConfiguration() {
        PugConfiguration configuration = new PugConfiguration();
        configuration.setCaching(false);
        configuration.setTemplateLoader(templateLoader());
        return configuration;
    }
    @Bean
    public ViewResolver viewResolver() {
        PugViewResolver viewResolver = new PugViewResolver();
        viewResolver.setConfiguration(pugConfiguration());
        return viewResolver;
    }
}
