我对 Doctrine 和PHP 5.5.6 Opcache
. opcache
关闭模块后一切正常。打开它后,我开始收到以下异常:
Fatal error: Uncaught exception 'Doctrine\ORM\Mapping\MappingException' with message 'Class "Admin\Models\Users\Role" is not a valid entity or mapped super class.' in vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php on line 336

我相信我的实体定义正确——正如我在开头提到的,一旦我禁用 opcache,一切都会按预期工作。为了初始化 Doctrine,我使用了这段代码:
// $this->getEntityPaths() returns an array of existing absolute paths, each of which is checked with realpath().
// $this->getProxyPath() returns a string with the absolute path, checked with realpath()
// $this->getInDevelopment() returns boolean and is set to TRUE
$config = Setup::createAnnotationMetadataConfiguration($this->getEntityPaths(), $this->getInDevelopment(), $this->getProxyPath());
$config->setAutoGenerateProxyClasses(true);
$dbParams = array(
'driver' => 'pdo_pgsql',
'host' => $this->getHost(),
'port' => $this->getPort(),
'user' => $this->getUser(),
'password' => $this->getPass(),
'dbname' => $this->getName()
);
$this->db = EntityManager::create($dbParams, $config);
我也试过这个配置:
$config = new Configuration;
$config->setProxyDir($this->getProxyPath());
$config->setProxyNamespace('DoctrineProxies');
$config->setAutoGenerateProxyClasses(true);
$driverImpl = $config->newDefaultAnnotationDriver($this->getEntityPaths());
$config->setMetadataDriverImpl($driverImpl);
$config->setMetadataCacheImpl(new \Doctrine\Common\Cache\ArrayCache());
$config->setQueryCacheImpl(new \Doctrine\Common\Cache\ArrayCache());
// the connection configuration
$dbParams = array(
'driver' => 'pdo_pgsql',
'host' => $this->host,
'port' => $this->port,
'user' => $this->user,
'password' => $this->pass,
'dbname' => $this->name
);
$this->db = EntityManager::create($dbParams, $config);
这是实体
/**
* Roles
*
* @Table(name="roles")
* @Entity
*/
class Role
{
/**
* @Id
* @Column(name="role_id", type="integer", nullable=false)
* @GeneratedValue(strategy="IDENTITY")
*/
private $role_id;
/**
* @Column(name="name", type="string", length=100, nullable=false)
*/
private $name;
}
为了简单起见,我AutoGenerateProxyClasses
只是为了确保我还通过生成代理对其进行了测试。不幸的是,我得到了同样的例外。我不确定如何解决这个问题以及问题到底是什么。它是一个教义错误吗?为什么OpCache
打开会导致Doctrine
异常并关闭它可以正常工作?我错过了配置部分或实体中的某些内容吗?
