Springboot2.6+Swagger3无法扫描到接口:No operations defined in spec!
@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(()) //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();
