Symfony2 ParamConverter 与@Annotation 无关(任何文件更改后都必须清除缓存) [英] Symfony2 ParamConverter not associated with @Annotation (cache must be cleared after any file change)

问题描述

我有一个控制器，它对路由、方法、模板和 ParamConverter 使用注释.
如果我在下一页加载时对文件进行任何更改(甚至是空格更改或注释)，则会发生以下错误

I have a Controller that uses Annotations for Route, Method, Template and ParamConverter.
If I make any change to the file (even a whitespace change or comment) on the next page load the following error occurs

Cannot import resource "/home/sites/MySite/src/Acme/Bundle/MyBundle/Controller/" from "/home/sites/MySite/app/config/routing.yml".

FileLoaderLoadException: Cannot import resource "/home/sites/MySite/src/Acme/Bundle/MyBundle/Controller/" from "/home/sites/MySite/app/config/routing.yml"

AnnotationException: [Semantical Error] The class "Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter" 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 "Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter". If it is indeed no annotation, then you need to add @IgnoreAnnotation("ParamConverter") to the _class_ doc comment of method Acme\Bundle\MyBundle\Controller\DefaultController::viewAction().

如果我清除缓存，它会再次工作，但只有在我进行另一次更改之前，它才会再次发生.在读取配置的注释信息时，它看起来似乎遇到了问题，但我不明白为什么实际上没有对任何注释进行更改时它起作用/不起作用.

If I clear my cache, then it will work again, but only until I make another change, then it happens again. It looks like it's hitting an issue when reading in the annotation info for config, but I can't understand why it works/doesn't work when the change isn't actually made to any annotation.

推荐答案

啊，这是一个已知错误，已在 FrameworkExtraBundle 中修复.

Ah, it's a known bug, fixed in the FrameworkExtraBundle.

https://github.com/symfony/symfony/issues/7283

现在要获得最新的，只需将该库的要求更改为 dev-master

And for now to get the latest, just change the requirement for that library to dev-master

"require": {
    ...
    "symfony/symfony": "2.2.*",
    "sensio/framework-extra-bundle": "dev-master",
   ...
},

并运行 composer update

and run composer update
