多选查询条件转换

//多选查询条件转换：
//"123,2342,123123"->List<String>if (Func.isNotEmpty(exerciseTrendReq.getBirdRecordIds())) {List<String> birdRecordIds = new ArrayList<>();Arrays.stream(exerciseTrendReq.getBirdRecordIds().split(",")).forEach(item -> birdRecordIds.add(item));}

日期格式转换：

日期格式转换：
日期加一天  转格式为'yyyy-MM-dd'
if (Func.isNotEmpty(exerciseTrendReq.getEndTime())) {Date endDate = DateUtil.parse(exerciseTrendReq.getEndTime(), DateUtil.PATTERN_DATE);exerciseTrendReq.setEndTime(DateUtil.formatDate(DateUtil.plusDays(endDate, 1)));}

日期格式化

LocalDateTime ->"yyyy-MM-dd HH:mm" "yyyyMMddHHmmss" "yyyy-MM-dd" "HH:mm:ss" 
DateUtil   DateTimeUtil.parseDateTime   方法
String time = DateUtil.format(birdHistoricalTrack.getPickTime(),"yyyy-MM-dd HH:mm");

MybatisPlus查询

List<BirdHistoricalTrack> birdHistoricalTracks = list(new QueryWrapper<BirdHistoricalTrack>().eq("bird_record_id",birdRecordId).gt(Func.isNotBlank(exerciseTrendReq.getStartTime()), "pick_time", exerciseTrendReq.getStartTime()).lt(Func.isNotBlank(exerciseTrendReq.getEndTime()), "pick_time", exerciseTrendReq.getEndTime()).orderByAsc("pick_time"));
