zf3视图找不到助手

Question

将站点从zf2移植到zf3时遇到麻烦。我已经向骨架应用程序添加了一个模块，并从那里构建了它，但是当在布局中调用自定义视图助手时，继续出现以下异常：

  

致命错误：未捕获错误：在C：\ workspace \ my-project \ vendor \ zendframework \ zend-servicemanager \ src \ Factory \ InvokableFactory.php：30中找不到类'Application \ View \ Helper \ MyHelper' >

注释此视图帮助器的调用只会在稍后导致另一个错误：

  

致命错误：方法Zend \ View \ Helper \ Navigation \ Menu :: __ toString（）不得引发异常，并捕获错误：在C：\ workspace \ my-中找不到类'Zend \ View \ Helper \ Translate'第0行上的project \ module \ Application \ view \ layout \ site.phtml

..建议查找视图助手的一般问题。这是我的配置：

my-project / config / modules.config.php

return [
    'Zend\Mail',
    'Zend\Paginator',
    'Zend\ServiceManager\Di',
    'Zend\Session',
    'Zend\I18n',
    'Zend\Mvc\Plugin\Prg',
    'Zend\Mvc\Plugin\Identity',
    'Zend\Mvc\Plugin\FlashMessenger',
    'Zend\Mvc\Plugin\FilePrg',
    'Zend\Mvc\I18n',
    'Zend\Mvc\Console',
    'Zend\Navigation',
    'Zend\Log',
    'Zend\Form',
    'Zend\Db',
    'Zend\Cache',
    'Zend\Router',
    'Zend\Validator',
    'Application',  
];

my-project / config / application.config.php

return [
    'modules' => require __DIR__ . '/modules.config.php',
    'module_listener_options' => [
        'module_paths' => [
            './module',
            './vendor',
        ],

        'config_glob_paths' => [
            realpath(__DIR__) . '/autoload/{{,*.}global,{,*.}local}.php',
        ],

         'config_cache_enabled' => false,
        'config_cache_key' => 'application.config.cache',
        'module_map_cache_enabled' => false,
        'module_map_cache_key' => 'application.module.cache',
        'cache_dir' => 'data/cache/',
        // 'check_dependencies' => true,
    ],
];

my-project / config / development.config.php

return [
// Additional modules to include when in development mode
'modules' => [
    'ZendDeveloperTools',
],
// Configuration overrides during development mode
'module_listener_options' => [
    'config_glob_paths' => [realpath(__DIR__) . '/autoload/{,*.}{global,local}-development.php'],
    'config_cache_enabled' => false,
    'module_map_cache_enabled' => false,
    ],
];

到目前为止，所有基本的基本应用程序配置。现在，对于我的模块配置，在其中注册了定制视图助手：

module / Application / config / module.config.php

<?php

namespace Application;

use Zend\ServiceManager\Factory\InvokableFactory;
use Zend\Navigation\Service\NavigationAbstractServiceFactory;

use Application\View\Helper\MyHelper;

return array(
    'controllers' => [
        'factories' => [
             Controller\IndexController::class => InvokableFactory::class,
        ],
    ],
    'view_manager' => [
        'display_not_found_reason' => true,
        'display_exceptions'       => true,
        'doctype'                  => 'HTML5',
        'not_found_template'       => 'error/404',
        'exception_template'       => 'error/index',
        //'template_map' => include __DIR__ . '/template_map.config.php',
        'template_map' => [
                'layout/layout'           => __DIR__ . '/../view/layout/site.phtml',
                'application/index/index' => __DIR__ . '/../view/application/index/index.phtml',
                'error/404'               => __DIR__ . '/../view/error/404.phtml',
                'error/index'             => __DIR__ . '/../view/error/index.phtml',
        ],
        'template_path_stack' => [
              __DIR__ . '/../view',
        ],
    ],


    'translator' => array(
        'locale' => 'en_US',
        'translation_file_patterns' => array(
            array(
            'type' => 'gettext',
            'base_dir' => __DIR__ . '/data/language',
            'pattern' => '%s.mo'
            )
        )
    ),

    'view_helpers' => [
        'aliases' => [
                'myHelper' => MyHelper::class,
        ],
        'factories' => [
                MyHelper::class => InvokableFactory::class,
        ],
    ],

    /**
     * In order to use multiple navigations, we need to the use the abstract factory.
     */
    'service_manager' => array(
        'abstract_factories' => array(
            NavigationAbstractServiceFactory::class,
        ),
        'factories' => array(
            'translator' => 'Zend\I18n\Translator\TranslatorServiceFactory'
        )
    ),
);

最后，自定义视图助手本身：

my-project / module / Application / src / Application / View / Helper / MyHelper.php

<?php

namespace Application\View\Helper;

use Zend\View\Helper\AbstractHelper;

class MyHelper extends AbstractHelper
{
        public function __invoke(){
            return 'foo';
        }
}

...这似乎都很简单，但是我看不到为什么找不到视图助手？
