Java Spring Boot:Swagger UI白标签错误

当我运行下面的程序时，当我访问localhost:8080/swagger-ui.html时，我得到一个白标签错误。我认为所有必需的依赖项（springfox-swagger 2、springfox swagger ui）都已导入并正确配置了swagger。请告诉我怎么了

招摇过市配置

@Configuration
@EnableSwagger2
public class SwaggerConfig {

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

尝试添加路径，您的代码将丢失此部分。 参考：

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