Java spring boot generator inheritance

[Queng123]

Is there a way to make inheritance, using the Java spring boot generator with a class that is not generated using the generator ?

I have a template like this (created for tests from the default template):

asyncapi: '2.0.0'
info:
  title: Streetlights API
  version: '1.0.0'
  description: |
    The Smartylighting Streetlights API allows you
    to remotely manage the city lights.
  license:
    name: Apache 2.0
    url: 'https://www.apache.org/licenses/LICENSE-2.0'

servers:
  production:
    url: kafka.bootstrap:{port} ## replace with redis server
    protocol: kafka
    variables:
      port:
        default: '9092'
        enum:
          - '9092'
          - '9093'

channels:
  event.lighting.measured:
    publish:
      bindings:
        kafka:
          groupId: my-group
      operationId: ResortSAEWorkerEvent
      message:
        $ref: '#/components/messages/ResortSAEWorkerEvent'



components:
  messages:
    ResortSAEWorkerEvent:
      summary: Inform about environmental lighting conditions for a particular streetlight.
      payload:
        $ref: "#/components/schemas/ResortSAEWorkerEvent"
      x-extends: Event

  schemas:
    ResortSAEWorkerEvent:
      type: object
      properties:
        correlationId:
          type: string
          description: Unique identifier for the correlation of the event.
        eventAt:
          type: string
          format: date-time
          description: Date and time when the event was generated.
        eventType:
          type: string
          description: Type of the event.
        provider:
          type: string
          description: Name of the provider that generated the event.
        data:
          type: object
          description: The event's payload.

My objective is to extend the model ResortSAEWorkerEvent to use Event.

I tried to do x-extends: Event, but it's not working.

Do you have any ideas ?

Feel free to ask if you need more datas or explainations 👍

In Spring Boot, if you want to use inheritance with classes generated by a generator like the one you've provided, you'll typically have to manually create the class that you want to extend, in this case, the Event class.

1.You need to manually create a Java class named Event that "ResortSAEWorkerEvent" can extend. This class should contain the properties and methods that you want to inherit.

2. Update the "ResortSAEWorkerEvent" class
   Once you have created the Event class, you can extend it in your ResortSAEWorkerEvent class.

For example:

Event.java
public class Event {
// Properties and methods that you want to inherit
}

ResortSAEWorkerEvent.java
public class ResortSAEWorkerEvent extends Event {
private String correlationId;
private String eventAt;
private String eventType;
private String provider;
private Object data;

// Getters and setters for properties

}
By doing this, "ResortSAEWorkerEvent" will inherit all the properties and methods from the Event class. You can then use these classes in your Spring Boot application as needed. Update your Spring Boot application to use these Java classes appropriately, such as in controllers, services, or repositories, depending on your application's architecture.
