You can try following configuration. The idea should be pretty straight forward. It does register artifacts in assets directory.

public class AppMvcConfiguration extends WebMvcConfigurerAdapter {

  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
      // Including all static resources.

      registry.addResourceHandler("/assets/**", 
                  "/css/**", 
                  "/img/**",
                  "/js/**"
             ).addResourceLocations("/assets/",
                  "/css/", 
                  "/img/",
                  "/js/"
      ).resourceChain(true)
       .addResolver(new PathResourceResolver());

       super.addResourceHandlers(registry);
  }
}
