RabbitMqBundle 连接未建立

Question

我在我的 sf2 项目中安装了https://github.com/videlalvaro/RabbitMqBundle，配置如下：

old_sound_rabbit_mq:
connections:
    default:
        host:     'localhost'
        port:     5672
        user:     'guest'
        password: 'guest'
        vhost:    '/'
        lazy:     false

producers:
    processing:
        connection: default
        exchange_options: { name: 'processing', type: direct }
        class: Assignment\Bundle\MainBundle\RabbitMq\Producer\ProcessingProducer

服务配置：

processing_producer:
    class: Assignment\Bundle\MainBundle\RabbitMq\Producer\ProcessingProducer
    arguments: []

制作者来源：

class ProcessingProducer extends Producer
{

public function __construct()
{
    parent::setContentType("application/json");
}

/**
 * @param string $msgBody
 * @param string $routingKey
 * @param array $additionalProperties
 */
public function publish($msgBody, $routingKey = '', $additionalProperties = array())
{
    $msgBody = json_encode($msgBody);

    parent::publish($msgBody, $routingKey, $additionalProperties);
}
}

在控制器中我尝试做一个测试发布：

public function indexAction()
{

    $this->get('old_sound_rabbit_mq.processing_producer')->publish(array('a' => 'b'));


    return $this->render('::Default/index.html.twig');
}

结果是：Error: Call to a member function channel() on a non-object

问题是在 Producer 构造函数中我没有将连接变量传递给父级

这里是正确的 Producer 构造函数：

public function __construct(AMQPConnection $conn, AMQPChannel $ch = null, $consumerTag = null)
{
    parent::__construct($conn, $ch, $consumerTag);

    parent::setContentType("application/json");
}
