But I do not care if any additional parameters are provided. Presently, when I validate my request with additional parameters. It fails, complaining that " Query parameter 'additional_param_1' is unexpected on path and Query parameter 'additional_param_2' is unexpected on path" Thanks for helping me out Spring ope-api validation: How to validate a field based on value of an other field in the Bean For instance I have a request which has a user object body with fields like name, age, country, zip code.
