我已经将响应设置为JSON但是得到了这个

无法编写JSON:没有为类org.json.JSONObject找到序列化程序,也没有发现创建BeanSerializer的属性(为了避免异常,请禁用SerializationFeature.FAIL_ON_EMPTY_BEANS)

@RequestMapping(value = "/customerlist", method = RequestMethod.POST)
public ResponseGenerator getCustomerList() {
    ResponseGenerator responseGenerator = new ResponseGenerator();
    try {

        responseGenerator.setCode(StatusCode.SUCCESS.code);
        responseGenerator.setMessage(StatusCode.SUCCESS.message);
        responseGenerator.setStatus(ResponseStatus.SUCCESS);
        JSONObject  data =   userService.getUserList();
        responseGenerator.setJSONData(data);

        return responseGenerator; //error here

    } catch (Exception e) {

        logger.error("Error while getting Customer List : ", e);
        e.printStackTrace();
        responseGenerator.setCode(StatusCode.GENERAL_ERROR.code);
        responseGenerator.setMessage(StatusCode.GENERAL_ERROR.message);
        responseGenerator.setStatus(ResponseStatus.FAIL);

        return responseGenerator;  
    }
}

userService.getUserList():

public JSONObject jsonResp;
public JSONObject getUserList() throws Exception{

    jsonResp =new JSONObject();
    //List<JSONObject> customers = new ArrayList<JSONObject>();
    JSONObject jsonResponse =   erpNextAPIClientService.getCustomerList();
    //ObjectMapper objectMapper = new ObjectMapper();
    //objectMapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY); …
