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());
    }
}

XML Configuration

<mvc:annotation-driven />
  <mvc:resources mapping="/staticFiles/path/**" location="/staticFilesFolder/js/"
                 cache-period="60"/>

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

spring.mvc.static-path-pattern=/resources/static/**

Since Spring 5 you just need to implement the interface WebMvcConfigurer   public class MvcConfig implements WebMvcConfigurer     This is because Java 8 introduced default methods on interfaces which cover the functionality of the WebMvcConfigurerAdapter class  See here   https   docs spring io spring docs current javadoc-api org springframework web servlet config annotation WebMvcConfigurerAdapter html

I have been working on Swagger equivalent documentation library called Springfox nowadays and I found that in the Spring 5 0 8  running at present   interface WebMvcConfigurer has been implemented by class WebMvcConfigurationSupport class which we can directly extend    import org springframework web servlet config annotation WebMvcConfigurationSupport   public class WebConfig extends WebMvcConfigurationSupport       And this is how I have used it for setting my resource handling mechanism as follows -    Override public void addResourceHandlers ResourceHandlerRegistry registry        registry addResourceHandler  swagger-ui html                addResourceLocations  classpath  META-INF resources          registry addResourceHandler   webjars                   addResourceLocations  classpath  META-INF resources webjars

Use org springframework web servlet config annotation WebMvcConfigurer  With Spring Boot 2 1 4 RELEASE  Spring Framework 5 1 6 RELEASE   do like this  package vn bkit   import org springframework context annotation Bean  import org springframework context annotation Configuration  import org springframework web servlet ViewResolver  import org springframework web servlet config annotation DefaultServletHandlerConfigurer  import org springframework web servlet config annotation EnableWebMvc  import org springframework web servlet config annotation WebMvcConfigurer  import org springframework web servlet config annotation WebMvcConfigurerAdapter     Deprecated  import org springframework web servlet view InternalResourceViewResolver    Configuration  EnableWebMvc public class MvcConfiguration implements WebMvcConfigurer         Bean     public ViewResolver getViewResolver             InternalResourceViewResolver resolver   new InternalResourceViewResolver            resolver setPrefix   WEB-INF             resolver setSuffix   html            return resolver              Override     public void configureDefaultServletHandling DefaultServletHandlerConfigurer configurer            configurer enable
