laravel 5.7中的类不存在反射异常错误

我的api.php

Route::get('getProducts' , 'ProductController@getProducts');

ProductController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Services\ProductService;


class ProductController extends Controller
{
    private $productService;

    public function __construct(ProductService $productService){
        $this->productService = $productService;
    }

    public function getProducts(){
        return $this->productService->get_products();
    }

    public function addProduct(Request $request){
        $all_data = array(
            'product_name' => $request['product_name'],
            'product_code' => $request['product_code'],
            'category_id' => $request['category_id'],
            'sub_category_id' => $request['sub_category_id'],
            'unit' => $request['unit']
        );
        return $this->productService->create_product($all_data);
    }
}

ProductService.php

namespace App\Http\Services;


use App\Http\Repositories\ProductRepositary;


    class ProductService
    {
        protected $productRepositary;
        public function __construct(ProductRepositary $productRepositary){
                $this->productRepositary = $productRepositary;
        }


        public function get_products(){
            return $this->productRepositary->get_products();
        }

        public function create_product($data){
            return $this->productRepositary->create_new_product($data);
        }
    }

ProductRepositary.php

<?php

namespace App\Http\Repositories;

use App\Product;

/**
 * 
 */
Class ProductRepositary
{
    public function getModel(){
        return new Product;
    }

    public function get_products(){
        $all_data = $this->getModel()->all();
        return $all_data;
    }

    public function create_new_product($data){
        $created = $this->getModel()->firstOrCreate($data)
        return $created;
    }
}

一切看起来很好，我不会错过，但我得到了这个错误 Class App\Http\Repositories\ProductRepositary does not exist 我试过了

• composer dump-autoload

• php artisan config：cache

• php artisan cache：清楚

• php artisan optimize：清楚

该文件位于右侧目录中

• app/Http/Repositories/ProductRepositary.php

但是仍然存在错误的一切，是否有人面临同样的问题，你找到的解决方案是什么？

在给予否定之前，请提供解决方案并给予负面评分
