            logger.info("用户缓存没有，系统重新获取");
            IUserDubboService userDubboService = StaticMethodGetBean.getBean(IUserDubboService.class);
            User user = userDubboService.getUserById(userId);
            if(null != user){
                userName = user.getName();
                userMap.put(String.valueOf(userId),user.getName());
            }
