Java 代码优化：使用 Stream API 简化 ScoreRecode 列表创建

private List createScoreRecodeList(final List tableSource, final String activityId) {\n return CollectionUtils.emptyIfNull(tableSource)\n .stream()\n .flatMap(item -> item.getScoreList().stream())\n .flatMap(scoreList -> TreeBuilderUtil.postorderErgodic(scoreList).stream())\n .map(scoreItem -> createScoreRecode(scoreItem, activityId))\n .collect(Collectors.toList());\n}
