        }catch(Exception e){
            e.printStackTrace();
        }
        return redissonClient;
    }
}

Solution: add

config.setCodec(new org.redisson.client.codec.StringCodec());

After adding this sentence, the exception is excluded.

//Specify the code. The default code is org.redisson.codec.jsonjacksoncode
// the previous spring data redis and the client jedis are encoded as org.springframework.data.redis.serializer.stringredisserializer
// after redisson is used, in order to ensure data compatibility between them, the code is modified to org.redisson.client.codec.stringcodec
