JedisPool单节点及Cluster通道单条/批量插入，读

@Autowired
private JedisPool jedisPool;

/**

*一、单节点通道批量插入
*/
Jedis jedis = jedisPool.getResource();
Pipeline jcp = jedis.pipelined();
Map<String, String> map = new HashMap<String, String>();
for (int i = 0; i < list.size(); i++) {
String key = RedisKeysDefine.RT_HASH_KEY + infols.get(i).getConnectorID();
map.put(RedisKeysDefine.RT_HASH_COLUMN_STATION_ID, stationId);
map.put( RedisKeysDefine.RT_HASH_COLUMN_STATUS, infols.get(i).getStatus()+"");
map.put(RedisKeysDefine.RT_HASH_COLUMN_PARKSTATUS, infols.get(i).getParkStatus() + "");
map.put(RedisKeysDefine.RT_HASH_COLUMN_LOCKSTATUS, infols.get(i).getLockStatus() + "");
map.put(RedisKeysDefine.RT_HASH_COLUMN_DATATIME, dataTime + "");
jcp.hmset(key, map);
}
jcp.sync();

jedis.close();

-------------------------------------------------------------------------------------------------

二、单节点redis缓存最新一条数据：

Jedis jedis = jedisPool.getResource();
String key = RedisKeysDefine.RT_HASH_KEY + info.getConnectorID();
if(jedis.hexists(key, RedisKeysDefine.RT_HASH_COLUMN_DATATIME)){
/**
* 判断当前数据是否比缓存更新
*/
Long lastDataTime = Long.parseLong(jedis.hget(key, RedisKeysDefine.RT_HASH_COLUMN_DATATIME));
if(dataTime<lastDataTime) {
jedis.close();
return 1;}

}
jedis.hset(key, RedisKeysDefine.RT_HASH_COLUMN_STATION_ID, stationId);
jedis.hset(key, RedisKeysDefine.RT_HASH_COLUMN_STATUS, info.getStatus() + "");
jedis.hset(key, RedisKeysDefine.RT_HASH_COLUMN_PARKSTATUS, info.getParkStatus() + "");
jedis.hset(key, RedisKeysDefine.RT_HASH_COLUMN_LOCKSTATUS, info.getLockStatus() + "");
jedis.hset(key, RedisKeysDefine.RT_HASH_COLUMN_DATATIME, dataTime + "");
jedis.close();

======================在集群Cluster模式下===============================

@Autowired
private JedisCluster jedisCluster;//在集群Cluster模式下利用通道批量查询

List<StakeRealInfo> list ；//获取存入Cluster的key

JedisClusterPipeline jcp = JedisClusterPipeline.pipelined(jedisCluster);
jcp.refreshCluster();//刷新集群信息，当集群信息发生变更时调用

List<Object> batchResult = null;
batchResult = jcp.syncAndReturnAll();//同步读取所有数据并按命令顺序返回一个列表

jcp.close();
