[BUG][JAVA] required on component only set on the getter of the model

We have a post method with a component as body.
This component has required field but sending a post with missing elements is allowed with the current generated code.
openapi yaml :
...
paths:
/events:
post:
tags:
- Event Data
operationId: createEvent
requestBody:
required: true
content:
application/json:
schema:
$ref: '#/components/schemas/event'
...
components:
schemas:
event:
title: event
description: event
type: object
required:
- eventName
properties:
eventName:
type: string

...

event class generated :
...
@JsonProperty("eventName")
private String eventName;
...
@NotNull
@Schema(name = "eventName", required = true)
public String getEventName() {
return eventName;
}

public void setEventName(String eventName) {
this.eventName = eventName;
}

--

We expect the @NotNull on the setter to or even on the Property.
Now we can call the create without any content in the body except '{}'

Reproduce the generated Spring model from the OpenAPI YAML and Maven configuration in the issue, then inspect the generated event class and the generator path that places @NotNull on getEventName(). Add or adjust coverage for a missing eventName in {}, and consider the issue done when generated validation rejects the request while preserving the required annotation semantics.
