我想使用openapi-generator-maven-plugin中的typemappings。我的openapi规范文件看起来像下面这样：

paths:
  /maintenance-windows-avr/{day}:
    get:
      summary: "Get active maintenance windows for day"
      tags:
        - Maintenance Windows AVR
      operationId: getMaintenanceWindows
      parameters:
        - in: path
          name: day
          required: true
          schema:
            type: string
            format: date
          description: day to return active maintenance windows
      responses:
        "200":
          description: "Success"
          content:
            application/json:
              schema:
                type: object
                items:
                  $ref: "#/components/schemas/ResponseListMaintenanceWindowAVRDto"
        default:
          description: unexpected error
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/ErrorDto"
components:
  schemas:
    ErrorDto:
      type: object
      required:
        - code
        - message
      properties:
        code:
          type: integer
          format: int32
        message:
          type: string

    MaintenanceWindowAVRDto:
      type: object
      required:
        - id
        - start
        - end
        - hosts
      properties:
        id:
          type: string
          format: uuid
          description: id of maintenance window
        start:
          type: string
          format: date-time
          description: when the maintenance window is going to start
        end:
          type: string
          format: date-time
          description: when the maintenance is going to end
        hosts:
          type: array
          items:
            type: long
            format: int64
            description: list of host ids

    ResponseListMaintenanceWindowAVRDto:
      type: object
      properties:
        data:
          type: array
          items:
            $ref: "#/components/schemas/MaintenanceWindowAVRDto"

这将生成如下所示的文件MaintenanceWindowsAvrApi和MaintenanceWindowsAVRDto：

我想将MaintenanceWindowsAvrApi文件中的LocalDate参数和从MaintenanceWindowsAVRDto文件开始和结束的两个OffsetDateTime字段Map到一个Instant（java.time.Instant）。
我尝试了很多方法，但没有一个能给我想要的结果。我的API pom文件：

<inputSpec>${project.basedir}/src/main/resources/META-INF/openapi-avr.yaml</inputSpec>
                            <generatorName>jaxrs-spec</generatorName>
                            
                            <configOptions>
                                <useSwaggerAnnotations>false</useSwaggerAnnotations>
                                <interfaceOnly>true</interfaceOnly>
                                <generatePom>false</generatePom>
                                <returnResponse>true</returnResponse>
                                <dateLibrary>java8</dateLibrary>
                                <java8>true</java8>
                                <useFlags>true</useFlags>

                            </configOptions>

如何使用typeMappings解决我的问题？
