Description

Description

When generating a java-microprofile client/server API interface with useSingleRequestParameter is true a @BeanParam request class is generated without getters. So when using the API interface as a server stub the request parameters cannot be retrieved.

Workaround is to have two configurations for the same spec, one with and one without using a single request parameter.

openapi-generator version

v7.16.0

Add getters for the fields

Research direction

The issue names no repository files or tests. Start by reproducing Java MicroProfile generation with useSingleRequestParameter=true and inspect the generated @BeanParam request class and server API interface; done when the request class exposes getters and the server stub can retrieve its parameters.
