因为想改变yii2的使用方式，改成yii2作为微服务，而前端使用前端框架之类的完成，但同时，我又想保留gii的使用，以便快速生成model和restful风格的controller，所以，就研究使用gii最低需要哪些条件？

显然，gii模块其实是使用了yii2的basic或advanced模板一样捆绑的jquery和bootstrap的，所以，我们事实上还是需要回到老路的。

在我的项目jsjxinfo下建立应用目录my，my下创建web目录作为该应用的文档根，里面放上入口文件index.php和空文件夹assets（运行时发布资源用）。在my下建立runtime目录和controllers目录，controllers目录下放SiteController（使用controllers目录是测试配置用的），不需要models和views目录。SiteController.php如下：

<?php

namespace my\controllers;

use yii\web\Controller;

class SiteController extends Controller
{
    public function actionIndex()
    {
        return 'my site index';
    }
}

因为需要引入jquery等资源，所以，my下建立assets目录并创建AppAsset.php，内容如下：

<?php

namespace my\assets;

use yii\web\AssetBundle;

class AppAsset extends AssetBundle
{
    public $basePath = '@webroot';
    public $baseUrl = '@web';
    public $css = [];
    public $js = [];
    public $depends = [
        'yii\web\YiiAsset',
    ];
}

我们希望打造自己的gii模板文件，所以，在my下创建giiTemplate目录（里面可以存放model等和gii对应的目录）。最关键的文件当然是入口文件index.php：

<?php

require __DIR__ . '/../../vendor/autoload.php';
require __DIR__ . '/../../vendor/yiisoft/yii2/Yii.php';

Yii::setAlias('@my', dirname(__DIR__));
// 以下为各个应用对应根目录
Yii::setAlias('@lab', dirname(__DIR__).'/../lab');
Yii::setAlias('@lock', dirname(__DIR__).'/../lock');

$app = (new yii\web\Application([
    'id' => 'my-gii',
    'basePath' => dirname(__DIR__),
    'controllerNamespace' => 'my\controllers',
    'vendorPath' => dirname(dirname(__DIR__)).'/vendor',
    'bootstrap' => ['gii'],
    'aliases' => [
        '@bower' => '@vendor/bower-asset',
        '@npm'   => '@vendor/npm-asset',
    ],
    'modules' => [
        'gii' => [
            'class' => 'yii\gii\Module',
//            'generators' => [
//                'model' => [
//                    'class' => 'yii\gii\generators\model\Generator',
//                    'template' => [
//                        'restful' => '@app/../giiTemplate/model/default',
//                    ]
//                ]
//            ]
        ]
    ],
    'components' => [
        'request' => [
            'cookieValidationKey' => 'this key must used',
        ],
        'db' => [
            'class' => 'yii\db\Connection',
            'dsn' => 'mysql:host=localhost;dbname=jsjxinfo',
            'username' => 'jsjxinfo',
            'password' => '*******',
            'charset' => 'utf8',
            // 'enableSchemaCache' => true,
        ]
    ]
]));
$app->run();
