Question

我在laravel中使用抽象类时遇到了问题。我只是按照本教程http://culttt.com/2014/03/17/eloquent-tricks-better-repositories进行操作，但是当我执行代码时出现错误＆＃34;未找到类＆＃34;。

我已将服务提供商中的课程绑定到我的代码

RepositoriesServiceProvider.php

<?php namespace Repositories;

use Illuminate\Support\ServiceProvider;

class RepositoriesServiceProvider extends ServiceProvider {

  public function register()
   {
    $this->app->bind(
   'Repositories\User\UserRepository',
   'Repositories\User\EloquentUserRepository',
   'Repositories\User\AbstractEloquentRepository'

   );
  }

}

?>

EloquentUserRepository.php

namespace Repositories\User;

use User;

class EloquentUserRepository extends AbstractEloquentRepository implements UserRepository{

    protected $model;

    public function __construct(User $model){

        $this->model = $model;

    }


    public function find($id){

        return User::find($id);

    }


    public function create($input){

        return User::create($input);

    }

}

?>

AbstractEloquentRepository.php

<?php 

  abstract class AbstractEloquentRepository{

    public function all(){

        return $this->model->all();

    }


}

?>

UserRepository.php

<?php

 namespace Repositories\User;

 interface UserRepository{

    public function all();

    public function find($id);

    public function create($input);
}

?>

UserController.php

<?php
  use Repositories\User\UserRepository as User;

  class UserController extends BaseController {

    /*
    |--------------------------------------------------------------------------
    | Default Home Controller
    |--------------------------------------------------------------------------
    |
    | You may wish to use controllers instead of, or in addition to, Closure
    | based routes. That's great! Here is an example controller method to
    | get you started. To route to this controller, just add the route:
    |
    |   Route::get('/', 'HomeController@showWelcome');
    |
    */


    public function __construct(User $user){

        $this->user = $user;

    }


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

    public function index()
    {
      return $this->user->all();
    }

    // public function showWelcome()
    // {
    //  return View::make('hello');
    // }






}

Answer 1

您的AbstractEloquentRepository.php文件中没有名称空间。

Answer 2

在终端中使用php artisan dump-autoload和composer dump-autoload重新生成所有类文件。愿这可以解决你的问题。

Answer 3

尝试一次绑定一个......

$this->app->bind('Repositories\User\UserRepository', function(){
   return new \Repositories\User\UserRepository();
}

未发现Laravel类+抽象类
