symfony constuctor error no such service exist

I am new with symfony i am trying to use the constructor but it doesn't work and i don't understand why

error:
Cannot autowire service \App\Controller\OutputController argument $product of method &__construct() references class App\Entity\Product but no such service exists.



<?php

    namespace App\Controller;
    use App\Entity\Product;

    class OutputController  {

        private $product;
        public function __construct(Product $product)    
        {
            $this->product = $product;
        }

        public function jsonFormat() {                     
            return json_encode($this->product->toArray());
        }

    }
?>

thanks

You use autowiring and you try to autowire a entity. By default they are not exposed as services by this config line from the default app/config/services.yml:

App\:
        resource: '../src/*'
        exclude: '../src/{Entity,Migrations,Tests,Kernel.php}'

As you can see, symfony exposes all files from src/* except from:

Entity,Migrations,Tests,Kernel.php

You should not expose entities as services and you should not rely on entities in your controller, Use services for that
