Symfony introduced annotations to configure cache, security, templates and Doctrine more than 10 years ago. They were available via an external bundle called SensioFrameworkExtraBundle.
With the introduction of PHP attributes, we turned those annotations into
attributes. However, you still had to install sensio/framework-extra-bundle
package to use them. For example:
use Sensio\Bundle\FrameworkExtraBundle\Configuration\IsGranted;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Symfony\Component\Routing\Annotation\Route;
#[Route('/comment/{postSlug}/new', methods: ['POST'], name: 'comment_new')]
#[IsGranted('IS_AUTHENTICATED_FULLY')]
#[ParamConverter('post', options: ['mapping' => ['postSlug' => 'slug']])]
public function addComment(Request $request, Post $post): Response
{
// ...
}In Symfony 6.2, we've introduced #[IsGranted], #[Cache], #[Template]
and #[ParamConverter] as native attributes, so you no longer need to
install any external package to use them.
In most applications, you will only need to update the imported namespace, without having to change anything in your code:
-use Sensio\Bundle\FrameworkExtraBundle\Configuration\IsGranted;
+use Symfony\Component\Security\Http\Attribute\IsGranted;
-use Sensio\Bundle\FrameworkExtraBundle\Configuration\Cache;
+use Symfony\Component\HttpKernel\Attribute\Cache;However, if you use #[ParamConverter], you'll need to make some changes to
turn it into the new #[MapEntity] attribute. The new attribute is applied to
properties, instead of to the entire method:
-use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
+use Symfony\Bridge\Doctrine\Attribute\MapEntity;
// ...
-#[ParamConverter('post', options: ['mapping' => ['postSlug' => 'slug']])]
-public function addComment(Request $request, Post $post): Response
+public function addComment(
+ Request $request,
+ #[MapEntity(mapping: ['postSlug' => 'slug'])] Post $post
+): Response
{
// ...
}We believe that PHP attributes are a great way to add metadata configuration to code. However, if you don't like them, you can skip them and keep configuring things in XML/YAML or directly in PHP code.
