To be able to serve static resources in Spring MVC application you need two XML-tags: and . The same in the Java-based Spring configuration will be:

@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {

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

    // equivalent for  tag
    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    // ... other stuff ...
}

Note that since @EnableWebMvc annotation is used there's no need to extend directly WebMvcConfigurationSupport, and you should just extend WebMvcConfigurerAdapter. See JavaDoc for @EnableWebMvc for details.
