本来打算将日期格式化然后返回select to_char(time,'yyyy-MM-dd hh:mm:ss') as start_time, phone_start_time as time from xxx结果然后就这样上线了，后续才发现不对劲，改为select to_char(phone_start_time,'yyyy-MM-dd HH24:MI:ss') as start_time, phone_start_time as time from xxx正常了然后想在返回格式里面加

问题 :线上的一个程序报了这个错误：redis.clients.jedis.exceptions.JedisClusterException: CLUSTERDOWN Hash slot not served at redis.clients.jedis.Protocol.processError(Protocol.java:121) at redis.clients.jedis.Protocol.process(Protocol.java:161) at redis.clients.jedis.
