swagger page is empty,

When I dont have @EnableWebMvc I can access

http://localhost:8080/swagger-ui.html

But looks like this:

enter image description here and at my network I have this 404 request enter image description here

When I enable I cannot access to that url (seem like doesnt exist)

at my startup logs I only see

My config file is this:

@Configuration
//@EnableWebMvc
@EnableSwagger2
public class WebConfig {
    @Bean
    public Docket productApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demo.web.rest"))
                .paths(PathSelectors.any())
                .build()
                .apiInfo(metaData());
    }

    private ApiInfo metaData() {
        ApiInfo apiInfo = new ApiInfo(
                "Spring Boot REST API",
                "Spring Boot REST API for Online Store",
                "1.0",
                "Terms of service",
                "someone",
                "Apache License Version 2.0",
                "https://www.apache.org/licenses/LICENSE-2.0");
        return apiInfo;
    }

}

and my main is:

@Configuration
@ComponentScan
@EnableAutoConfiguration

public class DemoApplication {


    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

and at my pom.xml

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.6.1</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.4.0</version>
        </dependency>

Any idea whats wrong?

If your WebConfig is in a different package than the DemoApplication class you may want to add the package to basePackages in @ComponentScan

If your application has defined a custom contextPath (server.contextPath in application.properties), then it has to be included in the url. http://localhost:8080/contextPath/swagger-ui.html

You could also try to change RequestHandlerSelectors.basePackage("com.example.demo.web.rest") to RequestHandlerSelectors.any() and see what happens.

Have your resouceHandler?

    @Override
    public void addResourceHandlers(final ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/swagger/**").addResourceLocations("classpath:/swagger/");
    }

I have this in a class that extends WebMvcConfigurerAdapter
