如何遍历redis集合 顶

List<String> list = new ArrayList<>();
if (redisService.exists("key")) {
    while (true) {
        ScanResult scanResult = redisService.sscan("key","0");
        List<String> elements = scanResult.getResult();
        if (elements != null && elements.size() > 0) {
            list.addAll(elements);
        }
        String cursor = scanResult.getStringCursor();
        if ("0".equals(cursor)) {
            break;
        }
    }
}
