Symfony2 AnnotationException您必须启用OPCache或ZendOptimizer

Question

我有基于Symfony2框架的应用程序。我已经转移到生产环境，网站运行良好（我试图调整缓存 - 我的托管是xcache）。但突然间，我有这样的错误：

Fatal error: Uncaught exception 'Doctrine\Common\Annotations\AnnotationException' with message 'You have to enable opcache.save_comments=1 or zend_optimizerplus.save_comments=1.' in /nfsmnt/hosting2_1/6/9/699be0da-dfbd-4651-90de-448d295bb741/playsport.sk/web/vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/AnnotationException.php:183 Stack trace: #0 /nfsmnt/hosting2_1/6/9/699be0da-dfbd-4651-90de-448d295bb741/playsport.sk/web/vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/AnnotationReader.php(162): Doctrine\Common\Annotations\AnnotationException::optimizerPlusSaveComments()

，我不能让我的托管opcache.save_comments（我没有特权，这是偶然的支付托管服务）。因此，我禁用了产品环境中的所有缓存并尝试重新运行网站。我目前的配置：

网/ app.php：

$loader = require_once __DIR__.'/../app/bootstrap.php.cache'; 

    // Enable APC for autoloading to improve performance. 
    // You should change the ApcClassLoader first argument to a unique prefix 
    // in order to prevent cache key conflicts with other applications 
    // also using APC. 

    //$apcLoader = new ApcClassLoader(sha1(__FILE__), $loader); 
    //$xcacheLoader = new \Symfony\Component\ClassLoader\XcacheClassLoader(sha1(__FILE__) . "PlaySport", $loader); 
    //$loader->unregister(); 
    //$xcacheLoader->register(true); 


    require_once __DIR__.'/../app/AppKernel.php'; 
    // require_once __DIR__.'/../app/AppCache.php'; 

    $kernel = new AppKernel('prod', false); 
    $kernel->loadClassCache(); 
    //$kernel = new AppCache($kernel); 

    // When using the HttpCache, you need to call the method in your front controller instead of relying on the configuration parameter 
    //Request::enableHttpMethodParameterOverride(); 
    $request = Request::createFromGlobals(); 
    $response = $kernel->handle($request); 
    $response->send(); 
    $kernel->terminate($request, $response); 

config_prod.yml：

imports: 
     - { resource: config.yml } 

    #framework: 
    # validation: 
    #  cache: xcache 

    #doctrine: 
    # orm: 
    #  metadata_cache_driver: xcache 
    #  result_cache_driver: xcache 
    #  query_cache_driver: xcache 

    monolog: 
     handlers: 
      main: 
       type:   fingers_crossed 
       action_level: error 
       handler:  nested 
      nested: 
       type: stream 
       path: "%kernel.logs_dir%/%kernel.environment%.log" 
       level: debug 
      console: 
       type: console 

我真的不知道该怎么办。仍然像以前一样得到错误。如何禁用Doctrine中的Annotation缓存或该问题的任何其他解决方案。谢谢！

Answer 1

问题解决了！这是由虚拟主机提供商和服务器配置引起的。 Opcache或Zend Optimizer配置不正确

Answer 2

您可以在您的主机上禁用Zend OpCache和/或Zend Optimizer +扩展吗？看起来，如果你禁用它，你将摆脱这个错误，因为Doctrine不会对opcache.save_comments参数进行额外的检查。

在\原则\ COMMON \注解\ AnnotationReader.php：

if (extension_loaded('Zend Optimizer+') && (ini_get('zend_optimizerplus.save_comments') === "0" || ini_get('opcache.save_comments') === "0")) { 
    throw AnnotationException::optimizerPlusSaveComments(); 
} 

if (extension_loaded('Zend OPcache') && ini_get('opcache.save_comments') == 0) { 
    throw AnnotationException::optimizerPlusSaveComments(); 
} 

禁用任何缓存，因为这种检查是在AnnotationReader类的构造函数，这是做不会解决这个错误不依赖任何缓存。

如果你不能，你仍然可以尝试参数设置opcache.save_comments 1与的ini_set PHP命令。
