How to get Swagger UI in SpringBoot (404 error)

Question

I'm trying to add Swagger UI to my REST Api but I can't find swagger ui path or there is a problem with it. Because when I check the paths where swagger ui must be I see the 404 error and I see

No mapping for GET /swagger-ui/index.html

error like that.

My pom.xml file:

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>

            <version>2.9.2</version>
        </dependency>



    </dependencies>

</project>

My swagger ui config class:

@Configuration
@EnableSwagger2
public class SpringFoxConfig extends SpringBootServletInitializer {
    @Bean
    public Docket swagger() {
        return new Docket(SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build();
    }
}

My application file:

@EnableWebMvc
@SpringBootApplication


public class FlightticketappApplication {

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

}

The default URL for the UI would be /swagger-ui.html instead of /swagger-ui/index.html
