Spring Boot：Swagger-UI 白标错误答案

【问题标题】：Spring Boot: Swagger-UI white label errorSpring Boot：Swagger-UI 白标错误
【发布时间】：2021-04-17 13:42:57
【问题描述】：

当我运行以下程序时，我在访问 localhost:8080/swagger-ui.html 时收到 白标错误。我认为所有必需的依赖项（springfox-swagger2、springfox-swagger-ui）都已导入并正确配置了 swagger。请指导我有什么问题...

Swagger 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();
    }
}

标签： java spring-boot swagger swagger-ui

【解决方案1】：

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

尝试添加路径，您的代码错过了这部分。参考：Swagger
