Validate request param names for optional fields - spring boot - spring

Question

If you have an endpoint described like this :
#GetMapping("/hello")
public String sayHello(#RequestParam(name= "my_id", required=false) myId, #RequestParam(name= "my_name") myName){
// return something
}
Issue:
The consumers of this endpoint could send invalid param names in the request;
/hello?my_name=adam&a=1&b=2 and it will work normally.
Goal:
Be able to validate optional request parameters names, using a proper way to do it.
Actual solution:
I've implemented a solution (For me it's not the right solution), where I've extends a HandlerInterceptorAdapter and register it in the WebMvcConfigurer :
/**
*
* Interceptor for unknown request parameters
*
*/
public class MethodParamNamesHandler extends HandlerInterceptorAdapter {
#Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
ArrayList<String> queryParams = Collections.list(request.getParameterNames());
MethodParameter[] methodParameters = ((HandlerMethod) handler).getMethodParameters();
Map<String, String> methodParametersMap = new HashMap<>();
if(Objects.nonNull(methodParameters)){
methodParametersMap = Arrays.stream(methodParameters)
.map(m -> m.getParameter().getName())
.collect(Collectors.toMap(Function.identity(),Function.identity()));
}
Set<String> unknownParameters = collectUnknownParameters(methodParametersMap, queryParams);
if(!CollectionUtils.isEmpty(unknownParameters)){
throw new InvalidParameterNameException("Invalid parameters names", unknownParameters);
}
return super.preHandle(request,response,handler);
}
/**
* Extract unknown properties from a list of parameters
* #param allParams
* #param queryParam
* #return
*/
private Set<String> collectUnknownParameters(Map<String, String> allParams, List<String> queryParam){
return queryParam.stream()
.filter(param -> !allParams.containsKey(param))
.collect(Collectors.toSet());
}
}
Drawbacks:
The drawbacks of this solution is that it's based on method parameters,
It will take the name myId instead of taking my_id, this could have a workaround by transforming the uppercase word to snake-case; but this is not a good solution because you can have something like this : sayHello(#RequestParam(name= "my_id", required=false) anotherName).
Question:
Is there a proper way to achieve this ?
