JedisDataException: WRONGTYPE Operation against a key holding the wrong kind of value

回答: JedisDataException: WRONGTYPE Operation against a key holding the wrong kind of value是一个Redis的异常错误。它表示在对一个键执行操作时，该键所持有的值的类型与操作的类型不一致。也就是说，使用了不同类型下的命令，操作了不同类型的数据。比如使用了string的命令，但是操作的是set类型的数据。这个错误通常发生在使用Redis的客户端库Jedis时。\[1\]\[2\]\[3\]
