        @Override
        public ConsumeConcurrentlyStatus consumeMessage(List<MessageExt> list, ConsumeConcurrentlyContext consumeConcurrentlyContext) {
            for (MessageExt messageExt : list) {
                // getting data from message.
                User user = Messages.getMessageBody(messageExt, deserializer);
                System.out.print(user.getName() + ":" + user.getAge() + "\n");
            }
            return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
        }
