Symfony2.1 [语义错误] 类 "Annotation"未使用@Annotation 进行注释

Question

我尝试将 Symfony 2.0 应用程序升级到 2.1，但我被阻止了......:(

这是当我尝试新的 Composer 更新时(我所有的包/包都已经是最新的)或当我尝试显示网页时的错误消息:

Loading composer repositories with package information
Updating dependencies                                     
Generating autoload files

  [Doctrine\Common\Annotations\AnnotationException]                                                                                                                                                                                                                                                                                                                                                              
  [Semantical Error] The class "Annotation" is not annotated with @Annotation. Are you sure this class can be used as annotation? If so, then you need to add @Annotation to the _class_ doc comment of "Annotation". If it is indeed no annotation, then you need to add @IgnoreAnnotation("Annotation") to the _class_ doc comment of class @Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter.  

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-update-cmd event terminated with an exception

  [RuntimeException]                                                         
  An error occurred when executing the "'cache:clear --no-warmup'" command.

我们已经为 Symfon2.0 应用程序使用了 composer。composer.json 文件:

"symfony/symfony":               "2.1.*@stable",
"doctrine/orm":                  "2.3.*@stable",

ParamConverter注解的使用:

   /**
     * @ParamConverter("someEntity", class="VendorSomeBundle:SomeEntity", options={"entity_manager" = "someentitymanagername"})
     */

我从 Symfony 2.1 复制/粘贴了 web/app.php、app/autoload.php 文件。

Answer 1

使用 Symfony2.1，您不再需要 ParamConverter 注释。以下示例将触发查询并为您提供所需的实体。

   /**
    * @Route("/id/randomroute", name="random_route")
    */
    public function highconnexionAction(Entity $entity)

但我不明白为什么你的注释不起作用...
