Support for Returning Response in Generated Code

[mathurinhauville]

Hi everyone,

I’m using the quarkus-openapi-generator-server extension to generate code for my REST API based on an OpenAPI specification. I have a use case where I’d like the generated server methods to return jakarta.ws.rs.core.Response instead of strongly typed objects derived from the OpenAPI schema.

Currently, the generated code strictly uses the return types defined in the OpenAPI specification, such as specific DTOs or inline schema objects. While this works well in many cases, it limits flexibility when I want to encapsulate responses into a Response object.

Here are my questions:

• Is there an existing configuration or workaround to force the generated methods to return Response instead of specific types?
• If not, would you consider adding an option to the extension (e.g., a configuration property) to enable this behavior?

Example:

// Current generated method
@Override
public ApiResponse uploadFile(Long petId, String additionalMetadata, InputStream file) {
    // Returns a specific DTO
}

// Desired behavior
@Override
public Response uploadFile(Long petId, String additionalMetadata, InputStream file) {
    // Allows greater flexibility for handling responses
}

Let me know if this is already supported or if additional context/examples would help clarify my use case.

Thank you for your work on this extension!
