                    List< Map<String, Object> > mapList = new ArraList<>();
                    mapList.forEach(list->{
                        list.forEach((key,value)->{
                            if (value instanceof Date){
                                value= DateUtil.format((Date)value,"yyyy-MM-dd HH:mm:ss");
                                list.put(key,value);
                            }
                            if (value instanceof LocalDateTime){
                                value= DateUtil.format((LocalDateTime)value,"yyyy-MM-dd HH:mm:ss");
                                list.put(key,value);
                            }
                        });
