目标不是可实例化的.Laravel 5 - 应用绑定服务提供商

Question

我收到这个错误:

BindingResolutionException in compiled.php line 1029:

Target [App\Models\Contracts\Repositories\IUserRepository] is not instantiable.

我的代码如下:

接口:

namespace App\Models\Contracts\Repositories;

use App\Models\Objects\DTO\User;

interface IUserRepository
{
    function Create( User $user );
}

具体:

namespace App\Models\Concrete\Eloquent;

use App\Models\Contracts\Repositories\IUserRepository;
use App\Models\Objects\DTO\User;

class EqUserRepository implements IUserRepository
{
    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    public function Create( User $user )
    {
        return User::create( [
                    'first_name' => $user->first_name,
                    'last_name' => $user->last_name,
                    'username' => $user->username,
                    'email' => $user->email,
                    'password' => bcrypt( $user->password ),
                ] );
    }

}

服务提供者:

<?php namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider {

    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }

    /**
     * Register any application services.
     *
     * This service provider is a great spot to register your various container
     * bindings with the application. As you can see, we are registering our
     * "Registrar" implementation here. You can add your own bindings too!
     *
     * @return void
     */
    public function register()
    {

            $this->app->bind(
                    'App\Models\Contracts\Repositories\IUserRepository', 
                    'App\Models\Concrete\Eloquent\EqUserRepository'
            );
    }

}

控制器:

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Contracts\Auth\Guard;
use Illuminate\Contracts\Auth\Registrar;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;

use App\Models\Contracts\Repositories\IUserRepository;
use App\Models\Objects\DTO\User;

class AuthController extends Controller
{
    protected $auth;
    private $userRepository;

    public function __Construct(  
            Guard $auth, 
            IUserRepository $userRepo )
    {
    ...

文件夹结构

我还看到我可能需要在我的composer.json中声明命名空间,所以我尝试了以下内容以及上面的内容:

"autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\\": "app/",
            "App\\Models\\Concrete\\Eloquent\\": "app/Models/Concrete/Eloquent/",
            "App\\Models\\Contracts\\Repositories\\": "app/Models/Contracts/Repositories/",
            "App\\Models\\Objects\\DTO\\": "app/Models/Objects/DTO/"
        }
    },

然后跑了 composer dump-autoload

我忘记做什么的任何想法？

Answer 1

我注意到compiled.php没有更新.

在项目的根文件夹的cmd行中运行此函数:

php artisan clear-compiled

Answer 2

如果您还运行以下错误:

Container.php第749行中的BindingResolutionException:目标[App\Contracts\TestContract]不可实例化.

清除配置缓存:

php artisan config:clear
