Symfony2:将APC更改为xcache

Question

因为APC中的一个错误，我不得不使用另一个缓存驱动器。我删除了APC并安装了xcache。config.php说你的配置看起来很好，可以运行Symfony。

我根据要求收到以下错误：

PHP Fatal error:  Uncaught exception 'RuntimeException' with message 'Unable to use ApcClassLoader as APC is not enabled.' in /var/.../app/bootstrap.php.cache:1039
Stack trace:
#0 /var/.../web/app.php(11): Symfony\Component\ClassLoader\ApcClassLoader->__construct('sf2', Object(Composer\Autoload\ClassLoader))
#1 {main}
thrown in /var/...app/bootstrap.php.cache on line 1039

如何告诉Symfony使用xcache而不是APC？

Answer 1

遇到了同样的问题，这就是我的做法：

在第 12 行中替换

$loader = new ApcClassLoader('sf2', $loader);

跟

$loader = new XcacheClassLoader('sf2', $loader);

（并定义正确使用声明）

后将

$loader = new ApcClassLoader('tcs_beta_prod', $loader);替换为 $loader = new XcacheClassLoader('tcs_beta_prod', $loader);并添加use SymfonyComponentClassLoaderXcacheClassLoader;我有这个错误Fatal error: Class 'SymfonyComponentClassLoaderXcacheClassLoader' not found in C:xampphtdocsedtwebapp.php on line 11.这是我的应用程序.php

<?php
use SymfonyComponentClassLoaderXcacheClassLoader;
use SymfonyComponentHttpFoundationRequest;
$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
// Use APC for autoloading to improve performance
// Change 'sf2' by the prefix you want in order to prevent key conflict with another application
$loader = new XcacheClassLoader('tcs_beta_prod', $loader);
$loader->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);
$request = Request::createFromGlobals();
Request::setTrustedProxies(array($request->server->get('REMOTE_ADDR'))); // per suggestion from Farid / Patrick to deal with ELB proxying
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

您没有为 XCache 定义 use 语句：

use SymfonyComponentClassLoaderXcacheClassLoader;
use SymfonyComponentHttpFoundationRequest;
use SymfonyComponentClassLoaderXcacheClassLoader;
