向zf3中的现有模块添加新控制器

在Zend framework 3中,我尝试将新控制器“ArticleController”添加到现有的模块城市中,但失败了。我张贴屏幕截图,我的文件夹结构和模块。配置。php。你能解释一下问题是什么吗?顺便说一句,当访问 http://0.0.0.0:7000/city

http://0.0.0.0:7000/article

<?php

namespace City;

use Zend\Router\Http\Segment;

return [
    'router' => [
        'routes' => [
            'city' => [
                'type'    => Segment::class,
                'options' => [
                    'route' => '/city[/:action[/:id]]',
                    'constraints' => [
                        'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                        'id'     => '[0-9]+',
                    ],
                    'defaults' => [
                        'controller' => Controller\CityController::class,
                        'action'     => 'index',
                    ],
                ],
            ],
            'article' => [
                'type'    => Segment::class,
                'options' => [
                    'route' => '/article[/:action[/:id]]',
                    'constraints' => [
                        'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                        'id'     => '[0-9]+',

                        'controller' => Controller\ArticleController::class,
                        'action'     => 'index',
                    ],
                ],
            ],
        ],
    ],

    'view_manager' => [
        'template_path_stack' => [
            'city' => __DIR__ . '/../view',
        ],
    ],
