Laravel 我是拉雷维尔的贝格纳。我们如何解决这个问题？

我是一个初学者，使用Laravel制作公告板。 我得到了这个错误：

找不到类“LaravelForum\Http\Controllers\Discussion”

以下是相关文件的内容： C:\laravel apps\bulletin board\app\Http\Controllers\discussioncontroller.php

<?php

namespace LaravelForum\Http\Controllers;

use Illuminate\Http\Request;

use LaravelForum\Http\Requests\CreateDiscussionRequest;

class DiscussionsController extends Controller
{

    public function __construct()
    {
        $this->middleware('auth')->only(['create', 'store']);
    }             

    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response 
     */

    public function index()
    {

        return view('discussions.index', [
            'discussions' => Discussion::paginate(5)
        ]);

    //    $discussions = Discussion::paginate(5);

    //     return view('discussions.index');

    }

    /**

    }

            'slug' => str_slug($request->title),
        ]);

        session()->flash('success', 'Discussin posted .');

        return redirect()->route('discussion.index');
    }

    /**

    public function destroy($id)
    {
        //

        $this->middleware('auth');
    }
