对函数方法注入一个实例报错了...?报错

public function index(IndexModel $model){
		
	$fields = Request::getRequest('page', 'int');
    $page = isset($fields) && $fields > 0 ? $fields : 1;
    //$model= new IndexModel;
    $ret = array();
    $ret['articleList'] = $model->getArticleList($page);//var_dump($ret);exit();
	$ret['pushArticleList'] = $model->getPushArticleList();
	$ret['tagList'] = $model->getTagList();
	$ret['pushIndex'] = $model->getPushIndex();
    $ret['commentList'] = $model->getCommentList();
	View::Transmit('newindex',$ret);
			
}

这是报错：

Catchable fatal error: Argument 1 passed to app\Controller\indexController::index() must be an instance of app\Model\IndexModel, none given, called in F:\Apache24\htdocs\blog\AliceFrameWork\Route.php on line 44 and defined in F:\Apache24\htdocs\blog\app\Controller\indexController.php on line 14

使用

//$model= new IndexModel;

是不会报错，但我想直接这样不行吗

public function index(IndexModel $model){
