WebRequest parameter should by ignored by Feign SpringMvcContract

See original GitHub issue

Currently following interface method:

ResponseEntity<ModelSO> getSubscriptionInformation(
       @RequestBody @ApiParam(name = "request", value = "The body of the request", required = true) 
       ModelSO model, // body 1
       WebRequest webRequest); // body2 ?

can’t be used as Feign Client:

java.lang.IllegalStateException: Method has too many Body parameters: public abstract org.springframework.http.ResponseEntity com.daimler.daivb.vts.snap.SubscriptionInformationSI.getSubscriptionInformation(java.lang.String,java.lang.String,java.lang.String,java.lang.String,com.daimler.daivb.vts.snap.SubscriptionRequestSO,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,org.springframework.web.context.request.WebRequest)

The same problem with

    @ResponseBody
    @RequestMapping(method = RequestMethod.POST, value = "/status_bso",
            produces = APPLICATION_JSON_VALUE, consumes = APPLICATION_JSON_VALUE)
    ResponseEntity<Response> statusBso(@RequestBody Request request, Errors errors);

where Error is org.springframework.validation.Errors

I can’t use Feign with spring validation in controller, because I have error Method has too many Body parameters
