问 提供的定义在呈现openapi时没有指定有效的版本字段。

EN

我正在将OpenAPI与我的项目集成在一起，当我访问url： http://127.0.0.1:11014/swagger-ui/index.html 时，会显示如下错误：

Unable to render this definition
The provided definition does not specify a valid version field.
Please indicate a valid Swagger or OpenAPI version field. Supported version fields are swagger: "2.0" and those that match openapi: 3.0.n (for example, openapi: 3.0.0).

这是OpenAPI配置：

package misc.config.openapi;
import io.swagger.v3.oas.models.ExternalDocumentation;
import io.swagger.v3.oas.models.OpenAPI;
import io.swagger.v3.oas.models.info.Info;
import io.swagger.v3.oas.models.info.License;
import org.springdoc.core.GroupedOpenApi;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 * https://springdoc.org/
 * https://github.com/springdoc/springdoc-openapi
@Configuration
public class OpenApiConfig {
    @Bean
    public GroupedOpenApi fortuneApi() {
        GroupedOpenApi.Builder builder = GroupedOpenApi.builder()
                .pathsToMatch("/fortune/**")
                .group("dddd");
        GroupedOpenApi groupedOpenApi = builder.build();
        return groupedOpenApi;
    @Bean
    public OpenAPI fortuneAPI() {
        return new OpenAPI()
                .info(new Info().title("Fortune API")
                        .description("Spring shop sample application")
                        .version("v0.0.1")
                        .license(new License().name("Apache 2.0").url("http://springdoc.org")))
                .externalDocs(new ExternalDocumentation()
                        .description("SpringShop Wiki Documentation")
                        .url("https://springshop.wiki.github.org/docs"));
}

我读过 Swagger..Unable to render this definition The provided definition does not specify a valid version field 的问题，并尝试了答案，两者都不起作用。我应该怎么做才能指定版本？如下所示的依赖关系：

    api "org.springdoc:springdoc-openapi-ui:1.6.9"

我做了一个最小的复制，发现正常的响应是json对象，但是问题响应返回字符串。这是正确的反应：

{
    "openapi": "3.0.1",
    "info": {
        "title": "Fortune API",
        "description": "Spring shop sample application",
        "license": {
            "name": "Apache 2.0",
            "url": "http://springdoc.org"
        "version": "v0.0.1"
    "externalDocs": {
        "description": "SpringShop Wiki Documentation",
        "url": "https://springshop.wiki.github.org/docs"
    "servers": [
            "url": "http://127.0.0.1:11018",
            "description": "Generated server url"
    "paths": {},
    "components": {}
}

这是我的项目中的问题响应：

"{\"openapi\":\"3.0.1\",\"info\":{\"title\":\"Fortune API\",\"description\":\"Spri......
