@Configuration//告訴Spring容器，這個類是一個配置類
@EnableSwagger2//啟用Swagger2功能
public class SwaggerConfig {@Beanpublic Docket createResApi(){return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select().apis(RequestHandlerSelectors.basePackage("com"))//com包下的所有API都交給Swagger2管理.paths(PathSelectors.any()).build();}private ApiInfo apiInfo(){return new ApiInfoBuilder().title("演示項目API")//標簽.description("演示項目")//描述.version("1.0")//版本.build();}
