The following candidates were found but could not be injected:
- Bean method 'redisConnectionFactory' in 'JedisConnectionConfiguration' not loaded because @ConditionalOnBean (types: org.springframework.data.redis.connection.RedisConnectionFactory; SearchStrategy: all) found beans of type 'org.springframework.data.redis.connection.RedisConnectionFactory' redisConnectionFactory
    
Consider revisiting the entries above or defining a bean of type 'org.springframework.data.redis.connection.jedis.JedisConnectionFactory' in your configuration.
