title: Swagger UI with swagger.yaml in SpringBoot
body: <p>We have a SpringBoot (version 1.5.12) REST Api with springfox-swagger2 and springfox-swagger-ui (version 2.9.2)</p>
  
  <pre><code>@EnableSwagger2
  public class Application extends SpringBootServletInitializer {
     @Bean
     public Docket swagger() {
         return new Docket(SWAGGER_2)
              .select()
              .apis(RequestHandlerSelectors.any())
              .paths(PathSelectors.any())
              .build();
      }
  </code></pre>
  
  <p>I can see the Swagger UI at <a href="http://localhost:8080/swagger-ui.html" rel="noreferrer">http://localhost:8080/swagger-ui.html</a></p>
  
  <p>How can I configure swagger-ui to read my swagger.yaml/json configuration file instead to generate it automatically? 
  I tried several configuration without success.</p>
