Implement Swagger in Maven project - Error 404

As indicated, and tried for days to implement swagger in the services layer of a maven project that has different modules. Watching tutorials, and view several ways to configure it without giving results, that's why I ask this question. Dependencies:

in the services layer I work in a specific package and this is where I have the swagger configuration class:

@Configuration
@EnableWebMvc
public class SwaggerConfig extends WebMvcConfigurerAdapter{ 

@Bean
public Docket api() { 
    return new Docket(DocumentationType.SWAGGER_2)  
      .select()                                  
      .apis(RequestHandlerSelectors.basePackage("com.apiux.docux.services"))              
      .paths(PathSelectors.any())                          
      .build().apiInfo(apiInfo());                                           
}
private ApiInfo apiInfo() {
    return new ApiInfoBuilder()
            .title("Servicios Sernac")                
            .description("Informacion sobre los servicios ECM para Sernac")
            .termsOfServiceUrl("http://en.wikipedia.org/wiki/Terms_of_service")                
            .license("Api-ux")
            .licenseUrl("http://www.api-ux.com")                
            .version("1.0")
            .build();
}

@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/");
}
}

the kind of services:

@Controller
@Api(value = "Read Api")
@Path("/ecm")
public interface EcmService {

/**
 * Obtenci�n de propiedades asociadas a un tipo de documento seg�n su
 * identificador
 * 
 * @param filtro
 * @return
 * @throws DocuxException
 */
@ApiOperation(value = "Obtiene las propiedades del documento")
@POST
@Path("/document_properties")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
Response getDocumentProperties(DocumentDataFilter filtro) throws DocuxException;}

and also searching the internet and that's why I did it, the AppConfig class

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "com.apiux.docux.services" })
public class AppConfig extends WebMvcConfigurerAdapter {

// ========= Overrides ===========

@Override
public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(new LocaleChangeInterceptor());
}

// ========= Beans ===========

@Bean(name = "localeResolver")
public LocaleResolver getLocaleResolver() {
    return new CookieLocaleResolver();
}

@Bean(name = "messageSource")
public MessageSource getMessageSources() {
    ReloadableResourceBundleMessageSource messageSource = new     ReloadableResourceBundleMessageSource();
    messageSource.setBasenames("/WEB-INF/resources/properties/error", "/WEB-INF/resources/properties/validation");
    messageSource.setCacheSeconds(0);

    return messageSource;
}

@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/");
}
}

e treated with http: localhost: 8080 / swagger-ui, http: localhost: 8080 / webcontext / swagger-ui and http: localhost: 8080 / webcontext / services / swagger-ui but still, nothing, nor to the documentation of the api I can enter.

I hope you can help me since I searched in several places and did not find the solution.
