传递给 Builder::__construct() 的参数 1 必须实现给定的接口 Knp\Menu\FactoryInterface、none

Question

使用 Symfony 3.3.12，我正在尝试将我的菜单构建器用作服务，这是在 AppBundle/Resources/config/services.yml 中配置并在主 config.yml 中导入为

imports:
   - { resource: "@AppBundle/Resources/config/services.yml" }

services.yml

##########################################################################
 # Menu Section   
 ##########################################################################
 AppBundle\Menu\Builder:
     arguments: 
         $factory: '@knp_menu.factory'
         $doctrine: '@doctrine'
         $token: '@security.token_storage'
     public: true
     tags:
         - { name: knp_menu.menu_builder, method: sidebarMenu, alias: sidebar }

但是当呈现为

时我得到这个错误

{{ knp_menu_render('sidebar', {'template': 'Menu/knp_sidebar_menu.html.twig', 'allow_safe_labels': true, 'currentClass':'active'}) }}

Argument 1 passed to Builder::__construct() must implement interface Knp\Menu\FactoryInterface, none given, called in /home/demousr/app/vendor/knplabs/knp-menu-bundle/Provider/BuilderAliasProvider.php on line 121

这是我的建造者

namespace AppBundle\Menu;

use \Knp\Menu\FactoryInterface;
use \AppBundle\Menu\Loader\NodeLoader;
use \Doctrine\Bundle\DoctrineBundle\Registry;
use \Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorage;

class Builder {

    private $factory;
    private $doctrine;
    private $token;

    public function __construct(FactoryInterface $factory, Registry $doctrine, TokenStorage $token) {
        $this->factory = $factory;
        $this->doctrine = $doctrine;
        $this->token = $token->getToken();
    }

    public function sidebarMenu(array $options) {

        $menu = $this->factory->createItem('root');
        $nodeLoader = new NodeLoader($this->factory, $this->token);

        $menu->setChildrenAttribute('class', 'nav nav-sidebar');

        $em = $this->doctrine->getManager();
        $tree = $em->getRepository('AppBundle:Menu\Menu')->findOneByMenu('main');
        $roots = $em->getRepository('AppBundle:Menu\MenuItem')->getRootNodesByTree($tree);

        foreach($roots as $root){

            $item = $nodeLoader->load($root);

            if(null !== $item){
                $menu->addChild($item);
            }
        }

        return $menu;
    }

}

我找不到我哪里错了

Answer 1

我刚刚更改了 MenuBuilder 中的 class 名称和 createSidebarMenu 的方法，并使用新的 class 名称更改了服务 ID，现在可以使用了。对我来说真是个大谜。

service.yml

##########################################################################
# Menu Section   
##########################################################################
AppBundle\Menu\MenuBuilder:
    arguments: 
        $factory: '@knp_menu.factory'
        $doctrine: '@doctrine'
        $token: '@security.token_storage'
    public: true
    tags:
        - { name: knp_menu.menu_builder, method: createSidebarMenu, alias: sidebar }

这是MenuBuilder.php

class MenuBuilder {

    private $factory;
    private $doctrine;
    private $token;

    public function __construct(FactoryInterface $factory, Registry $doctrine, TokenStorage $token) {
       $this->factory = $factory;
       $this->doctrine = $doctrine;
       $this->token = $token->getToken();
    }

    public function createSidebarMenu(array $options) {
        # code
    }
}
