错误:redis.clients.jedis.exceptions.JedisDataException: ERR Operation against a key holding the wrong kind of value
Reason: The key value already exists in the database, but the type set this time is different from the previous type, which conflicts.
For example, you set the vlaue type of the key to hash before, but this time you set the value type of the key to zadd, resulting in a type conflict.
Solution: Change the key value to avoid key value conflict.
