Specify the SchemaValidator when creating the OpenApiInteractionValidator

I would like to be able to configure the list of transformations performed on the SchemaObject by the SchemaValidator object, at its creation.

Moreover, I need to be able to pass an instance of SchemaValidator at the creation of the OpenApiInteractionValidator object.

The interest of being able to control the composition of the transformation chain is measured when one wants to integrate a transformer in the middle of it. For example, a transformer that can resolve the AllOf elements present in the API specification and thus be able to use additionalProperties: true without limitation.

For example:

public static class Builder {
...

public Builder withCustomSchemaValidator(final BiFunction<OpenAPI, MessageResolver, SchemaValidator> validator) {
    requireNonNull(validator, "A JSON schema validator is required");
    this.schemaValidator = validator;
    return this;
}
...

public OpenApiInteractionValidator build() {
    if (api == null) {
        this.api = new OpenApiLoader().loadApi(specSource, authData);
    }
    final MessageResolver messageResolver = new MessageResolver(levelResolver);
    if (schemaValidator == null) {
        schemaValidator = SchemaValidator::new;
    }
    return new OpenApiInteractionValidator(
        api,
        basePathOverride,
        messageResolver,
        whitelist,
        customRequestValidators,
        customResponseValidators,
        schemaValidator.apply(api, messageResolver));
}
...
}

‌

OpenApiInteractionValidator.createForSpecificationUrl("openapi.yaml")
  .withLevelResolver(LevelResolver.create()
      .withLevel("validation.schema.additionalProperties", ValidationReport.Level.IGNORE)
      .withLevel("validation.request.body.schema.additionalProperties", ValidationReport.Level.INFO)
      .build())
  .withCustomSchemaValidator { api, messages ->
      SchemaValidator(api, messages, listOf(
          SchemaDefinitionsInjectionTransformer.getInstance(),
          SchemaRefInjectionTransformer.getInstance(),
          AdditionalPropertiesInjectionTransformer.getInstance(),
          RequiredFieldTransformer.getInstance()))
  }
  .build()

Thanks for your feedback,

Kind regards
