FOSMessageBundle引發異常“消息必須是NewThreadMessage實例，“ CBundle \\ Entity \\ Message \\ NewThreadMessage”已給出”

Question

使用FOSMessageBundle時，我的代碼有些卡住。 我有一個newThreadAction像

/**
 * Create a new message thread
 *
 * @return Response
 */
public function newThreadAction()
{
     $form=$this->container->get('fos_message.new_thread_form.factory')->create();
     $formHandler=$this->container->get('fos_message.new_thread_form.handler');

    if ($message = $formHandler->process($form)) {
        return new RedirectResponse($this->container->get('router')->generate('fos_message_thread_view', array(
            'threadId' => $message->getThread()->getId()
        )));
    }

    return $this->container->get('templating')->renderResponse('CBundle:Message:start.html.twig', array(
        'form' => $form->createView(),
        'data' => $form->getData()
    ));

}

我的表單處理程序是

 namespace CBundle\Form\Handler;
 use FOS\MessageBundle\FormModel\AbstractMessage;
 use CBundle\Entity\Messsage\NewThreadMessage;
 use FOS\MessageBundle\FormHandler\NewThreadMessageFormHandler as cBaseHandler;
 class NewThreadMessageFormHandler extends cBaseHandler
 {
     /**
      * Composes a message from the form data
      *
      * @param AbstractMessage $message
      * @return MessageInterface the composed message ready to be sent
      * @throws InvalidArgumentException if the message is not a NewThreadMessage
      */
public function composeMessage(AbstractMessage $message)
{
    if (!$message instanceof NewThreadMessage) {
    // if (!$message instanceof NewThreadMessage) {
        throw new \InvalidArgumentException(sprintf('Message must be a NewThreadMessage instance, "%s" given', get_class($message)));
    }

    return $this->composer->newThread()
        // ->setSubject($message->getSubject())
        ->setSubject(" ")
        ->addRecipient($message->getRecipient())
        ->setSender($this->getAuthenticatedParticipant())
        ->setBody($message->getBody())
        ->getMessage();
}

}因此，當我提交消息的形式時，出現了類似的錯誤

    Message must be a NewThreadMessage instance, "CBundle\Entity\Message\NewThreadMessage" given

我的config.yml是

fos_message:
  db_driver: orm
  thread_class: AppBundle\Entity\Message\Thread
  message_class: AppBundle\Entity\Message\Message
  new_thread_form:
        type: app_user_new_thread.new_thread_form.type
        handler: app_user_new_thread_form.handler
        # handler: fos_message.new_thread_form.handler
        # model: FOS\MessageBundle\FormModel\NewThreadMessage
        model: CBundle\Entity\Message\NewThreadMessage
        # validation_groups: [ConnThread]

請幫助我，在此先感謝

我自己發現了問題。 這是因為use語句中的路徑錯誤，所以我想將該語句用作use CBundle\\Entity\\Message\\NewThreadMessage; 但是我做到了，就像use CBundle\\Entity\\Messsage\\NewThreadMessage; 請查看所包含課程的路徑
