Description

When generating the ApiClient for Spring RestClient, the Constructor accepts an ObjectMapper, but it is ignored if a RestClient is passed as argument.

openapi-generator version

openapi-generator-maven-plugin.version: 7.8.0

OpenAPI declaration file content or url

Generated Code:

    public ApiClient(RestClient restClient, ObjectMapper mapper, DateFormat format) {
        this(Optional.ofNullable(restClient).orElseGet(() -> buildRestClient(mapper.copy())), format);
    }

    private ApiClient(RestClient restClient, DateFormat format) {
        this.restClient = restClient;
        this.dateFormat = format;
        this.objectMapper = createDefaultObjectMapper(format);
        this.init();
    }

Expected Code:

    public ApiClient(RestClient restClient, DateFormat format) {
        this(restClient, createDefaultObjectMapper(format), format);
    }

    public ApiClient(RestClient restClient, ObjectMapper mapper, DateFormat format) {
        this.restClient = restClient;
        this.dateFormat = format;
        this.objectMapper = mapper;
        this.init();
    }
