求laravel5.2 controller 如何调用 models 的简单实例

<code><?php namespace App\Model;

use Illuminate\Database\Eloquent\Model;

class Bank extends Model
{
    protected $fillable=['card','user_id','name','bankName','province','city','branch'];

    public function user(){
        return $this->belongsTo(User::class);
    }

    public static function getBankById($id){
        return self::findOrFail($id);
    }
}</code>

<code><?php namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;

use App\Model\Bank;

class ActivityVoteController extends Controller
{
    public function index(){
        dd(Bank::getBankById(1));
    }
}</code></code>
