Description

When vertx transitioned from version 4 to 5, they split the http pool options out of the HttpClientOptions class and into a separate PoolOptions class. The PoolOptions is passed as a separate parameter into the WebClient factory method.

Currently, the vertx ApiClient's constructor only accepts a WebClientOptions config, meaning that when using vertx 5, it's impossible to configure the PoolOptions for the client.

openapi-generator version

7.22.0

OpenAPI declaration file content or url

The example generated client for vertx5 in the repo already shows the lack of PoolOptions configurability.

Generation Details

Run the generator for the vertx5 sample

Steps to reproduce

1. Run generate-samples.sh
2. Go to the generated sample code.
3. Notice that the ApiClient doesn't support a way to pass a PoolOptions into the underlying WebClient

Related issues/PRs

Vertx 5 support was added in #23563

Suggest a fix

When the useVertx5 option is enabled, the ApiClient needs to have another constructor that has a param for the PoolOptions config, and the code in ApiClient needs to be updated to pass that config into its WebClient creation.
