在Home模块里有个CommonController.class.php
在Admin模块里调用，代为如下：

<?php
namespace Admin\Controller;
use Think\Controller;
use Home\Controller\CommonController;
class IndexController extends Controller {

public function index(){

CommonController::hello(); //静态方法

$this->display();
}
}

错误提示为：Class 'Home\Controller\CommonController' not found
