openapi-generator-maven-plugin doesnt generate response headers for library – webclient

I have model in open-api v.3 spec. I use openapi-generator-maven-plugin to generate java client for library webclient (spring 5 – webflux). I want to send back to client file and http headers. Generated code doesn’t have method to get response headers.

Generated code for client doesn’t contains code which provide access to response headers. For example if I use library resttemplate there is method public MultiValueMap getResponseHeaders() . Is there a way how to get response headers with library -webclient ?

template for resttemplate library contains this: private MultiValueMap responseHeaders; link: github

code for webclient is here: github

OpenAPI generator was extended since 5.2 and now the webclient library has two methods for each endpoint one with suffix WithHttpInfo and with a return type Mono<ResponseEntity<T>> . See PR #9327. So if you have for example an endpoint getUser it generates:

Mono<UserDTO> getUser();

Mono<ResponseEntity<UserDTO>> getUserWithHttpInfo();

Then you can call a method with WithHttpInfo which returns ResponseEntity and call ResponseEntity#getHeaders

getUserWithHttpInfo().getHeaders()
