Spring 启动：Swagger-UI 白色 label 错误

Question

When I run the below program, I get a White Label Error when I am accessing localhost:8080/swagger-ui.html . I think all the required dependencies( springfox-swagger2, springfox-swagger-ui) are imported and configured the swagger properly. Please guide me on what's wrong...

Swagger Config

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket swagConfig() {
        return new Docket(DocumentationType.SWAGGER_2).select()
                .apis(RequestHandlerSelectors.basePackage("com.learn.microservices")).build();
    }
}

Answer 1

public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2).select().apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any()).build();
    }

Try adding the paths, your code miss this part. Ref: Swagger
