运行报错

可以正常的进行set操作，但是不能取出来，报错内容如下

springframework.data.redis.serializer.SerializationException: Could not read JSON: Illegal character ((CTRL-CHAR, code 0)): only regular white space (\r, \n, \t) is allowed between tokens

分析

查看redis里面的存储

value值是乱码。

各种百度、google查询结果，没找到，后来发现，redis的参数写错了，写过期时间写成了offset。

错误代码

正确代码

此问题 整整花费了5个多小时，找各种redis序列化的问题，一直以为是序列化配置的有问题。因此写代码一定要规范。
