Обработчик исключений не выполняется в проекте Spring

Я написал приведенный ниже код, чтобы реализовать обработку Spring Exception. Когда я запускаю код, он должен выдать ошибку в строке ниже, и должен выполниться соответствующий обработчик исключений. Но он не выполняется. Могу ли я узнать, что не так в моем коде. заранее спасибо

                throw new SpringException("Error", retStatus);

Код:

                @Controller
                public class RestController {


                @ExceptionHandler(SpringException.class)
                    public String handleCustomException(SpringException ex) {

                        String jsonInString = "{}";
                        JSONObject json = new JSONObject();
                        Map<String,String> errorMap = new HashMap<String,String>();
                        errorMap.put("errorMessage",ex.getMessage());
                        System.out.println("Inside exception handler");
                        json.putAll(errorMap);

                        jsonInString = json.toJSONString();
                        logger.info(jsonInString);

                        return jsonInString;


                    }


                @RequestMapping(value = "/v1/dist_list/{emailId}/members", method = RequestMethod.GET)
                    public @ResponseBody String getDistributionListMember(@PathVariable String emailId) throws Exception, SpringException {

                String retStatus = null;
                retStatus = dataServices.getDistributionListMember(emailId, callerId);


                if (!retStatus.isEmpty()) {
                                if (retStatus.contains("callerid is not valid")) {



                                    throw new SpringException("Error", retStatus);



                                }



                }


                }

Класс SpringException

                package com.uniteid.model;

            import org.springframework.http.HttpStatus;

            public class SpringException extends RuntimeException {
                private static final long serialVersionUID = 1L;

                private String errCode;
                private String errMsg;

                public String getErrCode() {
                    return errCode;
                }

                public void setErrCode(String errCode) {
                    this.errCode = errCode;
                }

                public String getErrMsg() {
                    return errMsg;
                }

                public void setErrMsg(String errMsg) {
                    this.errMsg = errMsg;
                }

                public SpringException(String errCode, String errMsg) {
                    this.errCode = errCode;
                    this.errMsg = errMsg;
                }
            }
