1、 redis 存储 hashmap:
Map<String,Integer> map = new HashMap<>();
for(int i = 0; i < 100; i++) {
map.put(i+"",i);
}
redisService.setCacheMapValue("testkey","k1",map);
存储后获取值:
Map<String,Integer> redRes = redisService.getCacheMapValue("testkey","k1");
Map<String,Map<String,Integer>> allRes = redisService.getCacheMap("testkey");
