用Lists.transform返回多个List
List<String> realNames = Lists.transform(applys, a -> {
String realName = a.getRealName(); if (StringUtils.isNotEmpty(realName)) {
StringBuilder stringBuilder = new StringBuilder(realName); realName = stringBuilder.replace(1, stringBuilder.length(), "*").toString(); } return realName; }).stream().filter(a -> StringUtils.isNotEmpty(a)).distinct().collect(Collectors.toList()); java中一对多的关系 取出
public BaseResponseVo<List<FeedBackVo>> query(FeedBackQo feedBackQo) {
PageHelper.startPage(feedBackQo.getPage(), feedBackQo.getLimit()); List<FeedBackVo> feedBackVos = feedBackMapper.query(feedBackQo); PageInfo<FeedBackVo> pageInfo = new PageInfo<>(feedBackVos); List<FeedBackVo> feedBackVoList = new ArrayList<>(); if (feedBackVos.size() > 0) {
// 取出所有的Id List<String> imgSpecs = Lists.transform(feedBackVos, t -> t.getId()); // 根据Id和类型查询图片 List<ImgEntity> imgEntities = imgMapper.queryByTypeAndBizids(TransactionType.FEEDBACK.getType(), imgSpecs); // 根据BizId分组 Map<String, List<ImgEntity>> imgMaps = imgEntities.stream().collect(Collectors.groupingBy(i -> i.getBizId())); for (int i = 0; i < feedBackVos.size(); i++) {
FeedBackVo feedBackVo1 = feedBackVos.get(i); if (imgMaps != null && imgMaps.get(feedBackVo1.getId()) != null) {
List<String> imgUrls = Lists.transform(imgMaps.get(feedBackVo1.getId()), t -> t.getUrl()); feedBackVo1.setImgList(imgUrls); } feedBackVoList.add(feedBackVo1); } } return BaseResponseVo.succ(pageInfo.getTotal(), feedBackVoList); } 版权声明：本文内容由互联网用户自发贡献，该文观点仅代表作者本人。本站仅提供信息存储空间服务，不拥有所有权，不承担相关法律责任。如发现本站有涉嫌侵权/违法违规的内容， 请联系我们举报，一经查实，本站将立刻删除。
