Answer 1

Use AMQP 0.9.1 basic.get to synchronously get just one message.

ConnectionFactory factory = new ConnectionFactory();
factory.setUri(uri);

Connection connection = factory.newConnection();
Channel channel = connection.createChannel();

channel.queueDeclare(QUEUE_NAME, true, false, false, null);

GetResponse response = channel.basicGet(QUEUE_NAME, true);
if (response != null) {
    String message = new String(response.getBody(), "UTF-8");
}

channel.close();
connection.close();
