如何在springfox-swagger2中执行请求主体对象有效负载

Question

如何使用springfox-swagger2重现以下OpenApi？

  parameters:
  - in: body
    name: user
    description: The user to create.
    schema:
      type: object
      required:
        - userName
      properties:
        userName:
          type: string
        firstName:
          type: string
        lastName:
          type: string

此处描述了这一点： https://swagger.io/docs/specification/2-0/describing-request-body/
