Quarkus Swagger MongoDB ObjectId Format

I'am writting app with quarkus-resteasy and mongodb. After quarkus OpenAPI has been installed, I saw that swagger UI does not correctly showing ObjectID format.

I am would like to see something like "61338f5b47bfc65136b5de30". How globally set ObjectID output format?

Because an objectId its what it is, thouse are the fields inside and what openapi is interpreting.

You can override what is being generated using the @Schema annotation, providing a format, an example and a type, in this case String, you can control what your swagger will contain.

@Schema(description = "Identifier of the Whatever", type = SchemaType.STRING, format = "XXXXXX", example="<Insert and example here>")

Because this is a value rather than a class that you can modify I think that you will need to put this annotation in all your DTO's that use these type.

Another option is using a Wrapper object, but this may modify your json structure depending on how you implement it.
