获取所有的KEY，以及删除，通过KEYS获取所有数据

public static final String str = "room:create:";

//获取key前缀room:create:所有的key

Set keys = stringRedisTemplate.keys(str + "*");

for(String key : keys){

    //System.out.println(key);
}

List strings = stringRedisTemplate.opsForValue().multiGet(keys);

for (int i = 0; i < strings.size(); i++){

   // System.out.println(strings.get(i));
}



//批量删除
//stringRedisTemplate.delete(keys);
List t1s = JSONUtils.parseArray(strings.toString(), T1.class);
