gii配置中能修改的属性好像就只有这些了：

   /**
     * @inheritdoc
     */
    public $controllerNamespace = 'yii\gii\controllers';
    /**
     * @var array the list of IPs that are allowed to access this module.
     * Each array element represents a single IP filter which can be either an IP address
     * or an address with wildcard (e.g. 192.168.0.*) to represent a network segment.
     * The default value is `['127.0.0.1', '::1']`, which means the module can only be accessed
     * by localhost.
     */
    public $allowedIPs = ['127.0.0.1', '::1'];
    /**
     * @var array|Generator[] a list of generator configurations or instances. The array keys
     * are the generator IDs (e.g. "crud"), and the array elements are the corresponding generator
     * configurations or the instances.
     *
     * After the module is initialized, this property will become an array of generator instances
     * which are created based on the configurations previously taken by this property.
     *
     * Newly assigned generators will be merged with the [[coreGenerators()|core ones]], and the former
     * takes precedence in case when they have the same generator ID.
     */
    public $generators = [];
    /**
     * @var integer the permission to be set for newly generated code files.
     * This value will be used by PHP chmod function.
     * Defaults to 0666, meaning the file is read-writable by all users.
     */
    public $newFileMode = 0666;
    /**
     * @var integer the permission to be set for newly generated directories.
     * This value will be used by PHP chmod function.
     * Defaults to 0777, meaning the directory can be read, written and executed by all users.
     */
    public $newDirMode = 0777;

呵呵

@aslanWho 自己试验了一下是这样的，感谢回复！

上一句已经跳转到其他页面了，想知道如果没有这一句会发生什么

看到源码是这么写，exit 终止执行，楼上的都是正确 也可以换成： die; return;

public function end($status=0,$exit=true)

{  
    if($this->hasEventHandler('onEndRequest'))  
        $this->onEndRequest(new CEvent($this));  
    if($exit)  
        exit($status);  
}

Yii::$app->end($status = 0, $response = null)表示终止程序；默认的表示正常终止，状态默认为0；其它状态均异常；
