Java 代码优化: 使用 Stream API 创建 ActivityScoreRecodeEntity 列表

private List createScoreRecodeList(final List tableSource, final String activityId) { return tableSource.stream() .filter(Objects::nonNull) .flatMap(scores -> convertScores(scores).stream()) .flatMap(scoreItem -> TreeBuilderUtil.postorderErgodic(scoreItem).stream()) .map(scoreItem -> createScoreRecode(scoreItem, activityId)) .collect(Collectors.toList()); }
