2：新增Config类,代码如下:

@EnableOpenApi
@Configuration
public class SwaggerConfig {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .pathMapping("/")
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.nercar.iom.ustb.controller"))
                .paths(PathSelectors.any())
                .build().apiInfo(new ApiInfoBuilder()
                        .title("SpringBoot整合Swagger")
                        .description("SpringBoot整合Swagger，详细信息......")
                        .version("9.0")
                        .contact(new Contact("","",""))
                        .build());
    }
}

@Api(value = "标准维护接口",tags = "标准维护相关接口", description = "标准维护controller，包含新增，修改，查询")

@ApiOperation(value = "查询所有匹配的标准",notes = "查询标准信息",produces = "application/json")
