Examples of com.rabbitmq.client.Connection.createChannel()

com.rabbitmq.client.Connection.createChannel()
Create a new channel, using an internally allocated channel number. @return a new channel descriptor, or null if none is available @throws IOException if an I/O problem is encountered


        // use a separate connection and channel to avoid race conditions with any operations that are blocked
        // waiting for the reconnection to finish...and don't cache anything otherwise you get the same problem!
        try {
            Connection connection = connectionFactory.newConnection(new Address[] { new Address(host) });
            Channel channel = connection.createChannel();


            channel.queueDeclare("testQueue", false, false, false, new HashMap<String, Object>());
            channel.queueBind("testQueue", "amq.topic", "#");


            channel.close();
