Laravel8.x报错问题，求解

在Homestead搭建的Laravel8.x的项目，使用Digon Api，配置api.php的信息如下：

```php
$api = app('Dingo\Api\Routing\Router');
$api->version('v1', function ($api) {
    $api->get('test', [\App\Http\Controllers\TestController::class,'index']);

    $api->get('name', ['as' => 'test.name', 'uses' => '\App\Http\Controllers\TestController::class@name']);

});

testconroller信息：

public  function  index(){

    }
    public function name(){
        $url = app('Dingo\Api\Routing\UrlGenerator')->version('v1')->route('text.name');
        dd($url);
    }

报错： Illuminate\Contracts\Container\BindingResolutionException

Target class [\App\Http\Controllers\TestController::class] does not exist.
求解！
