In Spring every request will go through the DispatcherServlet. To avoid Static file request through DispatcherServlet(Front contoller) we configure MVC Static content.

Spring 3.1. introduced the ResourceHandlerRegistry to configure ResourceHttpRequestHandlers for serving static resources from the classpath, the WAR, or the file system. We can configure the ResourceHandlerRegistry programmatically inside our web context configuration class.

• we have added the /js/** pattern to the ResourceHandler, lets include the foo.js resource located in the webapp/js/ directory
• we have added the /resources/static/** pattern to the ResourceHandler, lets include the foo.html resource located in the webapp/resources/ directory

@Configuration
@EnableWebMvc
public class StaticResourceConfiguration implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        System.out.println("WebMvcConfigurer - addResourceHandlers() function get loaded...");
        registry.addResourceHandler("/resources/static/**")
                .addResourceLocations("/resources/");

        registry
            .addResourceHandler("/js/**")
            .addResourceLocations("/js/")
            .setCachePeriod(3600)
            .resourceChain(true)
            .addResolver(new GzipResourceResolver())
            .addResolver(new PathResourceResolver());
    }
}

Spring Boot MVC Static Content if the file is located in the WAR’s webapp/resources folder.
