laravel-4 – Laravel：控制器不存在

php artisan dump-autoload

我收到以下错误

Mcrypt PHP extension required.

我按照https://askubuntu.com/questions/460837/mcrypt-extension-is-missing-in-14-04-server-for-mysql给出的指令,能够解决mcrypt问题.

之后,我运行php artisan dump-autoload命令,但仍然出现以下错误

{"error":{"type":"ReflectionException","message":"Class CoursesController does not exist","file":"/var/www/html/vendor/laravel/framework/src/Illuminate/Container/Container.php","line":504}}

这是我的routes.php文件的代码

Route::group(array('before' => 'adminauth','except' => array('/admin/login','/admin/logout')),function() {
    Route::resource('/admin/courses','CoursesController');
    Route::resource('/admin/teachers','TeachersController');    
    Route::resource('/admin/subjects','SubjectsController');
});

这是CoursesController.php文件的代码

<?php

class CoursesController extends BaseController
{

    public function index()
    {
        $courses = Course::where('is_deleted',0)->get();
        return View::make('admin.courses.index',compact('courses'));
    }

    public function create()
    {
        return View::make('admin.courses.create');
    }

   public function store()
    {
        $validator = Validator::make($data = Input::all(),Course::$rules);

        if ($validator->fails()) {
            $messages = $validator->messages();
            $response = '';
            foreach ($messages->all(':message') as $message) {
                $response = $message;
            }
            return Response::json(array('message'=>$response,'status'=>'failure'));
        } else {
            Course::create($data);
            return Response::json(array('message'=>'Course created successfully','status'=>'success'));
        }
    }

    public function edit($id)
    {
        $course = Course::find($id);
        return View::make('admin.courses.edit',compact('course'));
    }

    public function update($id)
    {
        $course = Course::findOrFail($id);
        $validator = Validator::make($data = Input::all(),Course::editRules($id));

        if ($validator->fails()) {
            $messages = $validator->messages();
            $response = '';
            foreach ($messages->all(':message') as $message) {
                $response = $message;
            }
            return Response::json(array('message'=>$response,'status'=>'failure'));
        } else {
            $course->update($data);
            return Response::json(array('message'=>'Course updated successfully','status'=>'success'));
        }
    }

    public function destroy($id)
    {
        Course::findOrFail($id)->update(array('is_deleted' => '1'));
        return Response::json(array('message'=>'Course deleted successfully','status'=>'success'));
    }

}
