openapi yaml file having callback not generating the callback code

[suryadip08]

I am trying to generate API & Model classes (java files) from OpenAPI (3.0.x) yaml file through swagger code generator (Server side). I am using suggestions from the swagger official website below:

https://swagger.io/docs/specification/callbacks/

First time I generated spring java classes (API & Models) without callback and then I generated the java classes with callback. But both are giving me same API and Model java files. Nowhere I am seeing any extra lines of code generated for adding callback in the yaml file. I am using https://editor.swagger.io/ (Swagger Smartbear) to generate the spring server side code. Please help.

Without callback :

paths:
  /subscribe:
    post:
      summary: Subscribe to a webhook
      requestBody:
        required: true
        content:
          application/json:
            schema:
              type: object
              properties:
                callbackUrl:   # Callback URL
                  type: string
                  format: uri
                  example: https://myserver.com/send/callback/here
              required:
                - callbackUrl
      responses:
        '201':

I am seeing the same. Don't think this has been implemented yet.
For java, I think this has been implemented in Code Generator.
