Hello I'm new to RabbitMQ, I'm trying to send an object between 2 applications, but it's not working I then found out that I need to serialize and deserialize the objects but it's still not working. When I'm sending a String there is no problem, but with objects it's not working suddenly there is no connection between the application, I'm not sure what I'm doing wrong.
Here is the Sender.java :
import org.apache.commons.lang3.SerializationUtils;
import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;
import java.io.ByteArrayOutputStream;
import java.io.ObjectOutput;
import java.io.ObjectOutputStream;
public class App {
private final static String QUEUE_NAME = "12345";
public static void main(String[] argv) throws Exception {
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("somehost");
factory.setUsername("guest");
// factory.setPassword( "password" );
//factory.setPort( 12345 );
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();
channel.queueDeclare(QUEUE_NAME, false, false, false, null);
Car car = new Car(4, 4, "Mercedes");
byte[] data = SerializationUtils.serialize(car);
channel.basicPublish("", QUEUE_NAME, null, data);
System.out.println(" [x] Sent '" + data + "'");
channel.close();
connection.close();
}
}
Here is Receiver.java :
import org.apache.commons.lang3.SerializationUtils;
import com.rabbitmq.client.*;
import java.io.IOException;
public class Recipient {
private final static String QUEUE_NAME = "12345";
public static void main(String[] argv) throws Exception {
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("Somehost");
factory.setUsername("guest");
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();
channel.queueDeclare(QUEUE_NAME, false, false, false, null);
System.out.println(" [*] Waiting for messages. To exit press CTRL+C");
Consumer consumer = new DefaultConsumer(channel) {
@Override
public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body)
throws IOException {
String message = new String(body, "UTF-8");
//byte [] data = new byte[];
Object object = SerializationUtils.deserialize(message.getBytes());
System.out.println(" [x] Received '" + object + "'");
}
};
channel.basicConsume(QUEUE_NAME, true, consumer);
}
}
@Override
public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body)
throws IOException {
//byte [] data = new byte[];
Object object = SerializationUtils.deserialize(body);
System.out.println(" [x] Received '" + object + "'");
}
};
Just deserialize directly from the body
variable
