@Configuration

public class RestConfig {

    @Bean
    public MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
        ObjectMapper mapper = new ObjectMapper();
        mapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
        MappingJackson2HttpMessageConverter converter =
                new MappingJackson2HttpMessageConverter(mapper);
        return converter;

    @Bean
    public ErpAppConfig configureErpApp() {
        // just to process the @PostConstruct
        return new ErpAppConfig();
    }

      @Bean
    public Docket productApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build();
    }

Add ResourceHandler such as `registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/"); registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");` — Kalaiselvan, Oct 09 '17 at 06:02
a file which extends `WebMvcConfigurerAdapter` In that override existing method `addResourceHandlers` for your ref: http://www.baeldung.com/swagger-2-documentation-for-spring-rest-api — Kalaiselvan, Oct 09 '17 at 06:41

Create a mapping for Swagger by override existing method addResourceHandler


public class AppConfig extends WebMvcConfigurerAdapter {
    @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/");
    }
}

Slightly different solution worked for me, also calling parent method: `super.addResourceHandlers(registry);`, check: https://github.com/springfox/springfox/issues/2037 – y.luis.rojo Mar 15 '18 at 18:55
