x-field-extra-annotation: "@javax.validation.Valid" properties not working when generating JAVA file from YAML

[ambilalmca]

I have a requirement to generate @Valid annotation for all generated DTO files at field level based on my Spec.

Created spec as below.

AccountDetailsRequestBody:
type: object
additionalProperties: false
x-field-extra-annotation: "@javax.validation.Valid"
properties:
payload:
type: object
x-field-extra-annotation: "@javax.validation.Valid"
additionalProperties: false
properties:
accountDetail:
$ref: '#/components/schemas/AccountDetail'

but while generating JAVA DTO file using below command, its not generating this @Valid annotation at field level.

java -Dmodels -DmodelDocs=false -jar openapi-generator-cli.jar generate -i ./input/system-api/common/indicators.yaml -g spring -o output-model/system-api -t ./spring-boot-lombok-actuator -p useActuator=true,useLombok=true,actuatorPath=/actuator

tried with latest version as well such as 6.0.0 and 7.9.0

As confirmed by another thread, its implemented in 6.0.0 itself. but not working.

Main objective is to avoid adding @Valid annotation for all nested objects to perform schema validations for request body object.
