Symfony:从控制器外部读取parameter.yml

I Want to read a pareameter from parameters.yml. the solution is to extend the Controller but I got this error :

Error: Call to a member function getParameter() on null

I know that the container is null, but i don't know how to get the container?

class Configuration extends Controller
{
    public function __construct()
   {
     $this->tempFolderPath = sys_get_temp_dir();
     $parameter = $this->container->getParameter('a');
   }
}

Any solution ? Any help ?

    this is not a best practice, but for me this is the only solution :( because in my code I have a static method that instantiate the hole class. so the solution will be.

    public function __construct()
    {
        $this->tempFolderPath = sys_get_temp_dir();
        global $kernel;
        $this->host = $kernel->getContainer()->getParameter('ws_host');
    }
