Return response from spring rest controller with query parameters

Question

I'd like to send 302 response with redirectUri and query parameters. I am able to fill the location but not sure how to include values as query parameters in response of the controller.

I have tried to add values to body but I'd like to send them in query parameters.

public ResponseEntity<Void> redirect(@RequestBody MultiValueMap<String,String> formVars, HttpServletResponse response) {
    String clientId = formVars.getFirst(CLIENT_ID);
    String redirectUri = formVars.getFirst(REDIRECT_URI);
    String redirectToken = formVars.getFirst(REDIRECTION_TOKEN);

    ResponseHandler<RedirectDto> redirectDtoResponseHandler = redirectService.redeemRedirectToken(redirectToken);
    if (!redirectDtoResponseHandler.isPresent()) {
        //handle error
    }

    redirectDtoResponseHandler.map(redirectDto -> toCookie(redirectDto.getCustomerSessionId()))
        .ifPresent(response::addCookie);

    URI uri = UriComponentsBuilder.fromHttpUrl(redirectUri).build().toUri();

    //I'd like to add clientId as query param in this response?
    return ResponseEntity.status(HttpStatus.FOUND).location(uri).build();
}

I'd like to add clientId as query param in this response?

Nope, it's 302 response it can't have body. We can return things either in params or headers — BountyHunter

UriComponents uriComponents = UriComponentsBuilder.newInstance()
      .scheme("http").host(redirectUri)
      .path("/").query("clientId={keyword}").buildAndExpand(clientId);
