通过cron job laravel调用函数

I have a xyz function in my ApiController

class Foo
{
    public function xyz()
    {
        // some code to insert data in database
    }
}

And I have defined a route

Route::get('xyz', ['as' => 'xyz', 'uses' => 'ApiController@xyz']);

Now I need to execute the code in xyz function in every 10 minutes

I have successfully set a crone job for one file, in that I am executing a php file by simply set command with full path of that file.

I am not getting any clue to execute only one function of a controller via crone job.

Thanks
