关于java:JavaString和List转换

1. 将json串转为list

String blackUids = "[1,2,3,4]";
List<Long> ids = JSONObject.parseArray(blackUids, Long.class);

2. 将逗号分隔字符串转为list

List<Long> uids = Arrays.asList(blackListUids.split(",")).stream().map(uid -> NumberUtils.toLong(uid)).collect(Collectors.toList());

3. 将字符串转为数组

String[] skuIds = skuLevelBonusMergeDTO.getSkuIds().split(",")
