本文主要是介绍Redis:WRONGTYPE Operation against a key holding the wrong kind of value,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
1.错误信息
redis.clients.jedis.exceptions.JedisDataException: WRONGTYPE Operation against a key holding the wrong kind of value
2.分析
当前程序中key的操作类型,并不与redis库中存在的key的类型相匹配。举例
第一次保存key,将其设置为key-value形式
[root@server3 src]# ./redis-cli -h 192.168.6.123 -p 6379 -a "{password}"
192.168.6.123:6379> set my_test_userid_001 "0001"
OK
192.168.6.123:6379> get my_test_userid_001
"0001"
第二次保存key,将其以key-map形式进行保存,则会报错
192.168.6.123:6379> hmset my_test_userid_001 user001 "0001" user002 "0002"
(error) WRONGTYPE Operation against a key holding the wrong kind of value
- 如果删除之前的key,则当前的操作可以进行:
192.168.6.123:6379> del my_test_userid_001
(integer) 1
192.168.6.123:6379> hmset my_test_userid_001 user001 "0001" user002 "0002"
OK
192.168.6.123:6379> hgetall my_test_userid_001
1) "user001"
2) "0001"
3) "user002"
4) "0002"
192.168.6.123:6379> hmget my_test_userid_001 user001
1) "0001"
192.168.6.123:6379> del my_test_userid_001
(integer) 1
3.1.临时解决
删除冲突key,类似于:
192.168.6.123:6379> del my_test_userid_001
3.2.根本解决
造成这个问题,肯定是程序在多处使用了同一个key
,并且是以不同的类型,有的以key-value类型,有的以key-map,有的以key-object。
查看程序,找到这个冲突,并修改。
