WebMvcConfigurerAdapter#addResourceHandlers adds a resource handler for serving static resources based on the specified URL path patterns. ResourceHandlerRegistry stores the registration of resources.

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**")
                .addResourceLocations("/static/");
    }
