如何使用openapi-generator-maven-plugin生成没有属性的基模型类

Question

我在我的java项目中使用maven插件：

            <groupId>org.openapitools</groupId>
            <artifactId>openapi-generator-maven-plugin</artifactId>
            <version>4.3.1</version>

在openapi配置文件(yml)中，我描述了一个post请求和响应模型：

post:
  tags:
    - instance
  summary: createInstances
  description: Creates instances for given ids
  operationId: createInstances
  requestBody:
    description: Params for creation
    required: true
    content:
      application/json:
        schema:
          $ref: '#/components/schemas/CreateInstancesRequest'
  responses:
    200:
      description: Ok
      content:
        application/json:
          schema:
            $ref: '#/components/schemas/CreateInstancesResponse'
    206:
      description: Partial Content
      content:
        application/json:
          schema:
            $ref: '#/components/schemas/PartialCreateInstancesResponse'

CreateInstancesResponse:
  type: object

PartialCreateInstancesResponseResponse:
  allOf:
    - $ref: '#/components/schemas/CreateInstancesResponse'
  required:
    - failedIds
  properties:
    failedIds:
      $ref: '#/components/schemas/Ids'

我希望它将生成一个不带字段的基本java类(CreateInstancesResponse)和一个继承类(PartialCreateInstancesResponse)。奇怪的是，生成了PartialCreateInstancesResponse类。但是基类不会生成。你能帮我解决这个问题吗？

看起来它还不受支持。你可以参考一个开放的问题here。

一个变通的办法是，在超类中添加虚拟属性。

"Pet": {
    "title": "AbstractPet",
    "type": "object",
    "properties": {
        "dummyProperty": {
            "type": "string",
            "description": "Workaround - OpenAPI generator does not consider definitions without properties"
        }
    },
    "description": "model containing all the details of a pet",
    "discriminator": {
        "propertyName": "petTypeName"
    }
}
