Pessoal tudo bem ?

Nao esta o projeto nao esta fazendo o carregamento do bootstrap, estou acompanhando a aula e fazendo o passo a passo, mas nao carrega. Dando o seguinte erro: ↓

        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");// para que o projeto veja os prefixos
        resolver.setSuffix(".jsp");// paginas que serao acessadas
        resolver.setExposedContextBeanNames("carrinhoCompras"); // metodo que expoe um item para o bean ficar exposto
        return resolver;
    }

        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        // local onde sera encontrado o caminho do arquivo messages.properties
        messageSource.setBasename("/WEB-INF/messages");
        // tipo de enconding.
        messageSource.setDefaultEncoding("UTF-8");
        // tempo que podemos salvar o arquivo sem necessariamente ter que subir
        // novamente o servidor.
        messageSource.setCacheSeconds(1);
        return messageSource;

    }

                TimeUnit.MINUTES);

        GuavaCacheManager manager = new GuavaCacheManager();
        manager.setCacheBuilder(builder);

        return new ConcurrentMapCacheManager();
    }

    /**

    @Bean
    public ViewResolver contetNegotiationViewResolver(ContentNegotiationManager manager) {
        List<ViewResolver> viewResolvers = new ArrayList<ViewResolver>();
        viewResolvers.add(internalResourceViewResolver());
        viewResolvers.add(new JsonViewResolver());
        ContentNegotiatingViewResolver resolver = new ContentNegotiatingViewResolver();
        resolver.setViewResolvers(viewResolvers);
        // metodo que ira verificar o que sera retornado
        resolver.setContentNegotiationManager(manager);

        return resolver;
    }

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

}

Caso eu retire o comentario do metodo addResourceHandlers, o erro é este: ↓

Failed to load resource: the server responded with a status of 404 () -  bootstrap.min.js
