JedisPool單節點及Cluster通道單條/批量插入,讀
@Autowired
private JedisPool jedisPool;
/**
*一、 單節點通道批量插入*/
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、單節點redis快取最新一條資料:
Jedis jedis = jedisPool.getResource();
String key = RedisKeysDefine.RT_HASH_KEY + info.getConnectorID();
if(jedis.hexists(key, RedisKeysDefine.RT_HASH_COLUMN_DATATIME)){
/**
* 判斷當前資料是否比快取更新
*/
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();
======================在叢集Cluster模式下===============================
@Autowired
private JedisCluster jedisCluster;//在叢集Cluster模式下利用通道批量查詢
List<StakeRealInfo> list ;//獲取存入Cluster的key
JedisClusterPipeline jcp = JedisClusterPipeline.pipelined(jedisCluster);
jcp.refreshCluster();//重新整理叢集資訊,當叢集資訊發生變更時呼叫
List<Object> batchResult = null;
batchResult = jcp.syncAndReturnAll();//同步讀取所有資料 並按命令順序返回一個列表
jcp.close();
