* Redis —— Scan、SScan、HScan、ZScan_redistemplate scan sscan hscan zscan

一、数据库基本命令

1. 扫描所有数据表

scan 0

2. 扫描hash表Real_Gps中的两条记录

HSCAN Real_Gps 0 MATCH * COUNT 2

二、RedisTemplate操作scan

//1. 一次性获取Real_Gps中数据
Map<Object, Object> map1 =redisTemplate.opsForHash().entries(env.getProperty("Real_Gps"));
//2. 使用Scan方式遍历获取Real_Gps中的数据 
ScanOptions scanOptions = ScanOptions.scanOptions().count(1).match("*").build();
Cursor<Entry<Object, Object>> cursor = redisTemplate.opsForHash().scan("Real_Gps", scanOptions);
while(cursor.hasNext()) {
	Map.Entry<Object, Object> entry = cursor.next();
	entry.getKey();
	entry.getValue();
}
