Handling error: RedisConnectionFailureException, Unable to connect to Redis;
nested exception is io.lettuce.core.RedisConnectionException:
Unable to connect to 192.168.66.129:6379
错误原因：Redis应连接本地Redis，将"192.168.66.129"改成”127.0.0.1“，注释掉”spring.redis.password“，并添加”spring.redis.timeout=5000“，如下所示： 问题解决！！！
