Use redis and rabbitmq key cloud cloud solution using vcap service in spring boot application

I can use the services REDIS and RABBITMQ, which are on the main page. While the bindings service I can get the credentials and use those credentials in my application.properties for the spring boot project.

But this config I am using is hardcoded in application.Properties In order to dynamically tweak this config I found out that we can use vcap services provided by pivot.

Therefore you want to use runtime credentials for redis and rabbimq.

See my code below for reference.

application.propeties

rabbitmq.host=hostname
rabbitmq.virtual-host=vhostanme
rabbitmq.username=username
rabbitmq.password=password
rabbit.mainqueue=abhi
rabbit.errorqueue=abc
redis.host=redishostname
redis.port=port
redis.password=password

My MessageConsumer class, in which I use this Conguration to get a message from a jumbbit jq queue and save for redis:

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

import javax.annotation.PostConstruct;
import javax.jms.ConnectionFactory;
import javax.jms.Message;

import com.es.consumer.config.Config;
import com.rabbitmq.jms.admin.RMQConnectionFactory;

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisShardInfo;

@Component
public class MessagesConsumer {
    @Autowired
    JmsTemplate jmsTemplate;
    final Logger logger = LoggerFactory.getLogger(MessagesConsumer.class);

    Jedis jedis;

    JedisShardInfo shardInfo;

    @PostConstruct
    public void init() {

        shardInfo = new JedisShardInfo(Config.getRedisHost(), Config.getRedisPort());
        shardInfo.setPassword(Config.getRedisPassword());
        jedis = new Jedis(shardInfo);
        jedis.connect();
        jedis.select(2);

    }

    @Bean
    ConnectionFactory connectionFactory() {

        RMQConnectionFactory connectionFactory = new RMQConnectionFactory();
        connectionFactory.setUsername(Config.getRabbitMqUsername());
        connectionFactory.setPassword(Config.getRabbitMqPassword());
        connectionFactory.setVirtualHost(Config.getRabbitMqVHost());
        connectionFactory.setHost(Config.getRabbitMqHost());
        return connectionFactory;

    }

    @SuppressWarnings("rawtypes")
    @Scheduled(fixedRate = 1)
    public void readQueueAndSaveData() {
// take message process it and save to redis as hmset

}}

      

        
        
        
      

    

Any help would be appreciated.
