Why does springfox-swagger2 UI tell me “Unable to infer base url.”

Question

Why does springfox-swagger2 UI tell me Unable to infer base url. As far as I know, I am using a typical Swagger spring-boot configuration.

As you can

Answer 1

Add @EnableSwagger2 annotation in the main file of Springboot application

@SpringBootApplication
@EnableSwagger2
public class SampleApplication {

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

}
