public static void main(String[] args) {

    RedisClient redisClient = RedisClient.create("redis://password@localhost:6739/0");
    StatefulRedisConnection<String, String> connection =redisClient.connect();

    RedisStreamCommands<String, String> streamCommands = connection.sync();

     List<String> supplierNames1 = new ArrayList<String>();
     supplierNames1.add("PaymentOption");
     supplierNames1.add("StartDate");
     supplierNames1.add("EndDate");
     supplierNames1.add("RateOfInterest");
     supplierNames1.add("RequiredLoanAmmount");

     List<String> supplierNames2 = new ArrayList<String>();
     supplierNames2.add(String.valueOf(123));
     supplierNames2.add(String.valueOf(765));
     supplierNames2.add(String.valueOf(347746));
     supplierNames2.add(String.valueOf(8347674));
     supplierNames2.add(String.valueOf(34875645));

    Map<List<String>, List<String>> body1 =  Collections.singletonMap(supplierNames1, supplierNames2);
        String messageId = streamCommands.xadd("demo", body1);

    System.out.println("my-stream code reference " + messageId);
    connection.close();
    redisClient.shutdown();
