I have tried to read all the key and values inside the specific redis hash key with the below java code,

  import redis.clients.jedis.Jedis;

        public class RedisDBExport {

          public static void main(String[] args) throws Exception {
            Jedis jedis = new Jedis("hostname", portno);
            jedis.auth("password");
            System.out.println("Connected to Redis");
            System.out.println("Connected to Redis:"+jedis.hgetAll("bookstore:englishauthor:usa:2017-08-27:online:subscriberlist"));
          }
        }

I am getting the below output in output ,

Connected to Redis Connected to Redis:{}

But in redis i could see the below entries are there,

row  key         value 

1   Kumar       {"totalbooks":0,"openbooks":[{"total":0}]}
2   Anuxx       {"totalbooks":1,"openbooks":[{"total":1}]}
3   Manux       {"totalbooks":2,"openbooks":[{"total":2}]}
4   Kumal       {"totalbooks":4,"openbooks":[{"total":4}]}
5   Anuxy       {"totalbooks":3,"openbooks":[{"total":3}]}
6   Manuy       {"totalbooks":5,"openbooks":[{"total":5}]}

Kindly suggest why i am getting this error,it will be helpful for me.

Is the key you typed in redis identical to the one in your code? Looks like 'onlline' should be 'online'.

As you can see the values that has retrieved from the hgetall is an Array i.e the return type . So try saving the values in a Set/Array and the try to display using an iterator.
