在我的spring控制器中，我返回了return new ResponseEntity(response, HttpStatus.OK);这样的响应体，但是我在postman中得到了{}作为响应。我在返回响应之前添加了一个日志行，并确认我有一个有效的响应体，其成员设置为相关值。

@RequestMapping(value = "/v2/endpoint", method = {RequestMethod.POST}, produces = "application/json")
public ResponseEntity<ResponseDto> getResponse(@Valid @RequestBody Request request,
                                                           @RequestHeader(name = "Accept-Language", defaultValue = "en") String locale,
                                                           @RequestHeader(name = "App-Version", required = false) Integer appVersion)  {
    try {
       
        ResponseDto responseDto = service.getResponse(request, locale, appVersion);
        log.info("responseDto : {}", responseDto);
        return new ResponseEntity(responseDto, HttpStatus.OK);
    }  catch (Exception ex) {
        log.error("Error ",  ex);
        throw  ex;
    }
}
