Controller中的Laravel ReflectionException

Question

I'm trying to inject the class HotelsTransformer without success with the next code:

UserTransformer

<?php 
namespace App\Transformers;

class UserTransformer extends Transformer
{
   ...
}

HotelsTransformer

<?php 
namespace App\Transformers;

class HotelsTransformer extends Transformer
{
   ...
}

ApiHotelsController

<?php 

namespace App\Http\Controllers\Api;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;

use \App\Hotel;
use \App\Transformers\HotelsTransformer;

class ApiHotelsController extends ApiController
{
   protected $HotelsTransformer;

   public function __construct(HotelsTransformer $HotelsTransformer)
   {
       $this->HotelsTransformer = $HotelsTransformer;
       dd($this->HotelsTransformer);
   }

When I inject UserTransformer, it's all OK, but when I change UserTransformer with HotelsTransformer it throws me this error.

I don't know why is this happening, because I cloned UserTransformer and change its name but same error persists.

Answer 1

Check your following namespace. May be it does not exist or namespace path is not correct

use \App\Transformers\HotelsTransformer;

Answer 2

尝试运行composer dumpauto命令。

Answer 3

Try running these commands from your terminal (from the root directory of your project)

// use sudo if it asks for the root permission
composer update
composer dump-autoload
php artisan config:clear

Rerun the app/project and try again.

These 2 commands will refresh composer loaded classes and clear the cache to make the project run freshly, hope it helps.!

Answer 4

Ok, I have solved it, the filename was wrong, changed: app/Transformers/HotelsTranformer.php to: app/Transformers/HotelsTranformer.php

1 hour spent on that like a crazy, good job.
