先检查一遍swagger扫描开启，enable：true；扫描路径配置正确后仍然还是不显示

springboot2.6+swagger2.9.2无法扫描到接口问题解决
多模块环境下,swaggerConfig配在公共模块,发现部分模块无法扫描到Controller接口。如下图所示：

经检查是部分模块忘记加以下配置了：

spring:mvc:pathmatch:matching-strategy: ant_path_matcher

附上SwaggerConfig（网上找的）
依赖为springfox-boot-starter

@Configuration
@EnableOpenApi
public class SwaggerConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.OAS_30)
                .enable(true) //是否启用swagger
                .apiInfo(apiInfo())
                // 设置哪些接口暴露给Swagger展示
                .select()
                // 扫描所有有注解的api，用这种方式更灵活
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
//                .paths(PathSelectors.any()) //这会把所有路径都给过滤了!
                .build();
    }

    private ApiInfo apiInfo() {
        // 用ApiInfoBuilder进行定制
        return new ApiInfoBuilder()
                // 设置标题
                .title("标题")
                // 描述
                .description("描述")
                // 作者信息
                .contact(new Contact("username", "website", "mail"))
                // 版本
                .version("版本号:" + "1.0")
                .build();
    }
