Symfony2 AnnotationException您必須啓用OPCache或ZendOptimizer

Question

我有基於Symfony2框架的應用程序。我已經轉移到生產環境，網站運行良好（我試圖調整緩存 - 我的託管是xcache）。但突然間，我有這樣的錯誤：

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()

，我不能讓我的託管opcache.save_comments（我沒有特權，這是偶然的支付託管服務）。因此，我禁用了產品環境中的所有緩存並嘗試重新運行網站。我目前的配置：

網/ 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 

我真的不知道該怎麼辦。仍然像以前一樣得到錯誤。如何禁用Doctrine中的Annotation緩存或該問題的任何其他解決方案。謝謝！

Answer 1

問題解決了！這是由虛擬主機提供商和服務器配置引起的。 Opcache或Zend Optimizer配置不正確

Answer 2

您可以在您的主機上禁用Zend OpCache和/或Zend Optimizer +擴展嗎？看起來，如果你禁用它，你將擺脫這個錯誤，因爲Doctrine不會對opcache.save_comments參數進行額外的檢查。

在\原則\ COMMON \註解\ 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(); 
} 

禁用任何緩存，因爲這種檢查是在AnnotationReader類的構造函數，這是做不會解決這個錯誤不依賴任何緩存。

如果你不能，你仍然可以嘗試參數設置opcache.save_comments 1與的ini_set PHP命令。
