Symfony4 Annotation routing does not work

symfony routing annotations symfony4

Solution 1

I found out my mistake. I used the wrong namespace for routing.

use Symfony\Component\Annotation\Route;

It should have been:

use Symfony\Component\Routing\Annotation\Route;

EDIT: I wanted to delete this question but the system wouldn't let me.

Solution 2

I had the same problem with my first Symfony 4 project on a standard apache web server.

Creating a .htaccess file in my public folder fixed the issue.

<IfModule mod_rewrite.c>
    Options -MultiViews
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ index.php [QSA,L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        RedirectMatch 302 ^/$ /index.php/
    </IfModule>
</IfModule>

Solution 3

In my case, adding 'apache bundle' solved the problem:

"composer require symfony/apache-pack"

You need this if you run symfony in browser via /public/.

Solution 4

I want to give additional advice about annotation errors in symfony4:

I handled my issue with that:

My project doesn't have config/routes/annotation.yaml, so create that file and write these lines:

// config/routes/annotations.yaml

controllers:
    resource: ../../src/Controller/
    type: annotation

Solution 5

Make sure you install annotations library with composer require annotations This was my issue and not other described here.

I just started learning Symfony. I am following this official tutorial exactly. Routing works fine when done with config/routes.yaml but on using annotations:

namespace App\Controller;

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Annotation\Route;

class LuckyController
{

    /**
     *  @Route("/lucky/number")
     */
    public function number(){

        $number = mt_rand(0, 100);

        return new Response(
            '<html><body><h1>MyLucky Number: ' . $number . '</h1></body></html>'
        );
    }
}

I get this error:

    Exception thrown when handling an exception
(Symfony\Component\Config\Exception\FileLoaderLoadException: [Semantical Error]
 The annotation "@Symfony\Component\Annotation\Route" in method 
App\Controller\LuckyController::number() does not exist, or could not be auto-loaded
 in C:\wamp\vhosts\mysymfony4\config/routes\../../src/Controller/ (which is
 being imported from "C:\wamp\vhosts\mysymfony4\config/routes/annotations.yaml"). Make sure
 annotations are installed and enabled.)

Your answers works. Any ideas why the official tutorial use Symfony\Component\Annotation\Route instead of Sensio\Bundle\FrameworkExtraBundle\Configuration\Route?

Because the FrameworkExtraBundle is no longer used in S4. I was puzzled you accepted this. A "composer require annotation" was all you really needed.

@Cerad I did composer require annotation as instructed by the tutorial. It didn't work

Hmmm. Seems unlikely. I just did a quick install and it works as expected. You really should not have to import the framework extra bundle classes. Just the symfony route like the original question shows. Might want to start a fresh project.

I added file in public/ catalog and my application run in prod server ;))

Had the same issue, and adding this file worked for me. I'm not sure why the Flex recipe didn't create this file automatically!

Installing sensio/framework-extra-bundle creates config/routes/annotation.yaml.

Before you check anything else, try this solution! Best suggestion for a new Symfony 4 project, especially when you use "php bin/console make:controller" to create your first controller.

This does not provide an answer to the question. Once you have sufficient reputation you will be able to comment on any post; instead, provide answers that don't require clarification from the asker. - From Review

Is "apache bundle" the literal name? Or do you mean the "apache bundle" or the "Apache bundle"?
Peter Mortensen about 2 years

Is "public" literal?

OK, the OP has left the building ("Last seen more than 2 years ago").

@PeterMortensen its not a bundle in technical way ... it's just a "pack" symfony.com/doc/current/setup.html#symfony-packs , I edited original post.
