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

One 、 Error message

I reported this error when deleting the cache ：WRONGTYPE Operation against a key holding the wrong kind of value

Two 、 Wrong meaning

Wrong type operation for the key holding the wrong type value  

  3、 ... and 、 The cause of the error

When I save the cache, I use zset structure ：

          redisTemplate.opsForSet().add(key,value);

But when I delete this cache, I use ：

          redisTemplate.opsForZSet().remove(key,value);

Therefore, data structure inconsistency leads to , Error when deleting .

Four 、 terms of settlement

  When deleting the cache structure, change to Set：

 redisTemplate.opsForSet().remove(key,value);

Keep the same structure when saving and deleting .

This is the problem I encountered in my actual work , I hope it helps you ~
