Getting body of RabbitMQ with properties

I am reading from RabbitMQ like this: 

connection = factory.newConnection();
ch = connection.createChannel() ;
String queueName = managerProps.getProperty("rmq.queue.name");
ch.queueDeclare(queueName ,true,false,false, null) ;

while (true) {
    GetResponse chResponse = ch.basicGet(queueName, false);
    logger.info("----" + new String(chResponse.getBody(), "UTF-8") + " ---\n");
}

And here is what I see in the log: 

[Thread-5] INFO com.mycompany.RmqReader - ----?? ♣wx .com.rabbitmq.jms.client.message.RMQTextMessage $b1213c86-10f4-4113-bd2f-45aaabce083f   ♠ ←rmq.jms.meamqpQueueNameq ~ ☺L ♫amqpRoutingKeyq ~ ☺L ☼destinationNameq ~ ☺xp ☺ t ↕jms.durable.queuest !MY.Queue.Name ~ ♦q ~ ♦z  ☻O ↔rmq.jms.message.delivery.mode♦   ☻ ↓rmq.jms.message.timestamp♣  ☺j?∟ ↑rmq.jms.message.priority♦   ♦ →rmq.jms.message.expiration♣         ↕rmq.jms.message.i 'ID:b1213c86-10f4-4113-bd2f-45aaabce083f   ♂ ◄objectTransaction☺☺ ►templateEndpoin -jtemplate://JSONDeliveryTemplateParallel.java ►deliveryLocatio +jms:queue:My.Queue.Name ►destinationIndex♦   ☺ ♫subsCutOffTime♦     ♀breadcrumbI ♀1149808347.0 ◄globalDeliveryUID♦ ?]? ►subscriptionNam §option_session_pubsub ◄originalMessageI ♀1149808347.0 ↨subscriptionDeliveryUID♦ ??8 ¶transactionTimestamp♣  ☺j??(z  ♥R   ♥M[

Why do I see the headers here? And how do I actually extract the body?

This is what I see in console

Looks like you have used RMQConnectionFactory to publish the data which is jms compliant and now you are using non jms ConnectionFactory

Please see sample consumer using RMQConnectionFactory https://github.com/kunhaj/samples/blob/master/rabbitmq/src/main/java/RabbitMqConsumer.java

import com.rabbitmq.jms.admin.RMQConnectionFactory;
import javax.jms.*;

/**
 *  docker run -d --hostname my-rabbit --name 
 *   some-rabbit  -p 5672:5672 -p 15672:15672 rabbitmq:3-management
 */
public class RabbitMqConsumer {
    public static void main(String[] args) throws Exception {
        RMQConnectionFactory connectionFactory = new RMQConnectionFactory();
        connectionFactory.setUsername("guest");
        connectionFactory.setPassword("guest");
        connectionFactory.setVirtualHost("/");
        connectionFactory.setHost("localhost");
        connectionFactory.setPort(5672);
        connectionFactory.setDeclareReplyToDestination(false);
        Connection connection = connectionFactory.createConnection();
        connection.start();
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        Queue queue = session.createQueue("TEST-QUEUE");
        drainQueue(session, queue);
    }

    protected static void drainQueue(Session session, Queue queue) throws Exception {
        MessageConsumer receiver = session.createConsumer(queue);
        Message msg = receiver.receiveNoWait();
        while (msg != null) {
            String msgBody = ((TextMessage) msg).getText();
            System.out.println("recieved" + msgBody);
            msg = receiver.receiveNoWait();
        }
    }
}
