HTTP État 400 - Requis paramètre de Chaîne 'walletName' n'est pas présent

Je travaille avec Java/Spring MVC RESTful app et obtenir 400 HTTP status error tout en faisant un POST demande. Le @RestController méthode est fournie,

@RequestMapping(value = "/generateAddress", method = RequestMethod.POST)
    public ResponseEntity<WalletInfoWrapper> generateAddress(@RequestParam("walletName") String walletName,
                                                             @RequestParam("currencyName") String currencyName) {

        logger.info("walletName {} and currencyName {}", walletName, currencyName);

        //return if the wallet name or the currency is null
        if (Objects.isNull(walletName) || Objects.isNull(currencyName)) {
            return new ResponseEntity<WalletInfoWrapper>(HttpStatus.NOT_ACCEPTABLE);
        }

        WalletInfo walletInfo = walletService.generateAddress(walletName, currencyName);

        if (Objects.isNull(walletInfo)) {
            return new ResponseEntity<WalletInfoWrapper>(HttpStatus.NOT_ACCEPTABLE);
        }

        WalletInfoWrapper walletInfoWrapper = new WalletInfoWrapper();
        walletInfoWrapper.setName(walletInfo.getName());

        return new ResponseEntity<WalletInfoWrapper>(walletInfoWrapper, HttpStatus.CREATED);
    }

La POST demande dans le Postman fourni ci-dessous,

Le message d'erreur informe, Required String parameter 'walletName' is not present

Je peux également fournir le code pour le services et la dataase couches pour l'observation de la liste déroulante des opérations. Quel est le problème ici?

UPDATE

J'ai mis à jour le Postman demande de ce genre et ayant toujours le même message d'erreur,

UPDATE 1

J'ai toujours le même problème,

Je POST avec les données,

{"walletName":"puut","currencyName":"Bitcoin"}

Le code est fourni ci-dessous,

@RequestMapping(value = "/generateAddress", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<WalletInfoWrapper> generateAddress(@RequestBody WalletWithMoneyRequest walletWithMoneyRequest) {

        String walletName = walletWithMoneyRequest.getWalletName();

        String currencyName = walletWithMoneyRequest.getCurrencyName();

        logger.info("walletName {} and currencyName {}", walletName, currencyName);

        //return if the wallet name or the currency is null
        if (Objects.isNull(walletName) || Objects.isNull(currencyName)) {
            return new ResponseEntity<WalletInfoWrapper>(HttpStatus.NOT_ACCEPTABLE);
        }

        WalletInfo walletInfo = walletService.generateAddress(walletName, currencyName);

        if (Objects.isNull(walletInfo)) {
            return new ResponseEntity<WalletInfoWrapper>(HttpStatus.NOT_ACCEPTABLE);
        }

        WalletInfoWrapper walletInfoWrapper = new WalletInfoWrapper();
        walletInfoWrapper.setName(walletInfo.getName());

        return new ResponseEntity<WalletInfoWrapper>(walletInfoWrapper, HttpStatus.CREATED);
    }

La POJO est fourni,

private class WalletWithMoneyRequest {

        String walletName;

        String currencyName;

        public WalletWithMoneyRequest(String walletName, String currencyName) {
            this.walletName = walletName;
            this.currencyName = currencyName;
        }

        public WalletWithMoneyRequest() {
        }

        public String getWalletName() {
            return walletName;
        }

        public String getCurrencyName() {
            return currencyName;
        }

        public void setCurrencyName(String currencyName) {
            this.currencyName = currencyName;
        }

        public void setWalletName(String walletName) {
            this.walletName = walletName;
        }
    }

C'est le message d'erreur,
