Could not read JSON: Cannot construct instance of java.util.ArrayList$SubListRedis反序列化异常

Mon, 04 Sep 2023 04:11:56 +0000

错误信息：
Could not read JSON: Cannot construct instance of java.util.ArrayList$SubList(no Creators, like default construct, exist): no default no-arguments constructor found

原因是读取Redis缓存时，报错异常导致！

原因是缓存中是集合ArrayList中含有SubList，因为SubList不能序列化和反序列化，导致解析失败。

解决办法：

1、若存在使用SubList方法，只需要重新new 下：

原代码：       resultList = regionDistributionVOList.subList(ZERO, FOUR);

改正后：       resultList = new ArrayList<>(regionDistributionVOList.subList(ZERO, FOUR));
或者:            resultList.addAll(regionDistributionVOList.subList(ZERO, FOUR));

2、若通过 Lists.partition(ZERO, TEN)获取的，则需要将subList转为ArrayList

用： Lists.newArrayList(subList)
