Php Symfony编码密码不工作

我正在使用Symfony2。我正在尝试在我的应用程序中创建一个用户，并将其信息保存在数据库中。在任何情况下，我都可以将数据持久化到数据库中，它确实存储了数据，但它没有加密密码。这是我的密码。有人帮我吗？谢谢

    //search form
    $search_form = $this->createForm(new UserSearchType());

    //user form
    $user = new User();
    $form = $this->createForm(new UserAdminType(), $user);

    if ($request->isMethod('POST')) {

        //get the Account of this user and set it on the user being created.             
        $account = $this->getUser()->getAccount();
        $user->setAccount($account);

        //encode password and set on user
        $factory = $this->get('security.encoder_factory');
        $encoder = $factory->getEncoder($user);
        $password = $encoder->encodePassword($user->getPassword(), $user->getSalt());
        $user->setPassword($password);

        $form->bind($request);
        if ($form->isValid()) {

            $em = $this->getDoctrine()->getManager();
            $em->persist($user);
            $em->flush();

            //set flash message
            $message = "User ".$user->getUsername()." has been created with password ". $password;
            $this->get('session')->getFlashBag()->add('message', $message);

            return $this->redirect($this->generateUrl('user_list'));
        }
    }

    return array(
        'heading' => 'Create User',
        'form' => $form->createView(),
        'search_form' => $search_form->createView(),
    );

下面是我更新密码的步骤

 $password = $postData['password']['first'];
 $factory = $this->get('security.encoder_factory');
 $encoder = $factory->getEncoder($user);
 $password = $encoder->encodePassword($password, $user->getSalt());

有没有办法调试这行下面的$user var（比如var_dump）：$user->setPassword（$password）？？显示您的

security.yml

（或等效格式）文件是否使用FOSUserBundle？如果是这样，您可以使用

setPlainPassword

设置密码，它将处理加密和加密。
