java8一个List转化为另外一个List

List filterTags = Lists.newArrayList();

    List<Promotion> promotionList = filterTags.stream().map(f -> {
        Promotion tag = new Promotion(context);
        tag.setLabel(f);
        tag.setCode(f);
        return tag;
    }).collect(Collectors.toList());

java实现置顶排序功能

使用的是当前时间作为排序

默认是拿到上一个排序号减一作为当前排序的排序号,但是有可能会重复排序号

所以当前排序号后面的数据要顺延-1处理

 @Override
    public void topSort(String targetContentId) {
        if (targetContentId.equals(this.getContentEntity().getId())) {
            return; // 排序目标是自己直接返回
        }
        checkLock();
        //上一条数据
        CmsArticle prev = this.getArticleService().getById(targetContentId);
        Long topFlag = prev.getTopFlag() - 1;
        this.content.setTopFlag(topFlag);
        //排序时间重复 则后面的数据顺延-1
        LambdaQueryWrapper q = new LambdaQueryWrapper<CmsArticle>()
                .eq(CmsArticle::getCategoryId, prev.getCategoryId())
                .ne(CmsArticle::getTopFlag, '0')
                .ne(CmsArticle::getTopFlagType, 'N')
                .le(CmsArticle::getTopFlag, topFlag)
                .orderByDesc(CmsArticle::getTopFlag).orderByDesc(CmsArticle::getSortFlag);
        List<CmsArticle> articles = this.getArticleService().getContentMapper().selectList(q);
        recursiveSort(articles, 0, topFlag);
        // 批量更新文章信息
        this.getArticleService().saveOrUpdateBatch(articles);
        this.getArticleService().updateById(content);
    }

    public void recursiveSort(List<CmsArticle> articles, int start, Long topFlag) {
        if (start >= articles.size()) {
            return;  // 递归结束条件:已经遍历完整个列表
        }
        CmsArticle currArticle = articles.get(start);
        if (currArticle.getTopFlag().equals(topFlag)) {
            currArticle.setTopFlag(topFlag - 1);  // 顺延-1处理
            topFlag--;
        }
        recursiveSort(articles, start + 1, topFlag);  // 递归遍历下一篇文章
    }
