部署spring mvc应用程序后放置css，img和js文件

我是 Spring 季mvc的新手，我有一些问题：

1）我可以从jsp页面访问WEB-INF目录中的img，css和js吗？

文件夹结构是：

webapp
  - WEB-INF
     - css
     - js
     - img

2）我有WebMvcConfig类，扩展了WebMvcConfigurerAdapter：

@Configuration
@EnableWebMvc
@Import（{BeanConfig.class，CacheConfig.class}）
公共类WebMvcConfig扩展WebMvcConfigurerAdapter {

@Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/css/**").addResourceLocations("/resources/css/").setCachePeriod(31556926);
        registry.addResourceHandler("/img/**").addResourceLocations("/resources/img/").setCachePeriod(31556926);
        registry.addResourceHandler("/js/**").addResourceLocations("/resources/js/").setCachePeriod(31556926);
    }   

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

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new ControllerInterceptor());
    }  

    @Bean
    public InternalResourceViewResolver getInternalResourceViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }    
    @Bean
    public ContentNegotiatingViewResolver getContentNegotiatingViewResolver() {
        ContentNegotiatingViewResolver resolver = new ContentNegotiatingViewResolver();
        ArrayList<View> defaultViews = new ArrayList<View>();
        MappingJacksonJsonView jsonView = new MappingJacksonJsonView();
        jsonView.setPrefixJson(true);
        defaultViews.add(new MappingJacksonJsonView());
        resolver.setDefaultViews(defaultViews);
        resolver.setOrder(1);
        return resolver;
    }

    @Bean
    public ControllerInterceptor getLoggingInterceptor() {
        return new ControllerInterceptor();
    }
}

我想访问文件夹：/ resources / css，/ resources / img和/ resources / js，

web.xml文件的一部分：

<servlet>

<servlet的名称> MVC-调度</ servlet的名称>
<servlet的类> org.springframework.web.servlet.DispatcherServlet </ servlet的类>
<INIT-PARAM>
<PARAM名称> contextClass </ PARAM名称>
<PARAM值>
org.springframework.web.context.support.AnnotationConfigWebApplicationContext
</ PARAM值>
</ INIT-param>
<INIT-PARAM>
<PARAM名称> contextConfigLocation的</ PARAM名称>
<PARAM值>
config.WebMvcConfig
</ PARAM值>
</ INIT-param>
</ servlet的>

<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

文件夹结构是：

webapp
   - WEB-INF
   - resources
        - css
        - js
        - img

但它不起作用
