当我打开php opcache时,学说很吓人

Fatal error: Uncaught exception 'DoctrineORMMappingMappingException' with message 'Class "AdminModelsUsersRole" is not a valid entity or mapped super class.' in vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php on line 336

我相信我的实体被正确定义 – 正如我在开始时提到的,一旦我禁用opcache,一切都按预期工作.要初始化Doctrine,我正在使用这段代码：

// $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 DoctrineCommonCacheArrayCache());
$config->setQueryCacheImpl(new DoctrineCommonCacheArrayCache());

// 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,我打开了AutoGenerateProxyClasses,但是为了确保我还通过生成代理来测试它.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,究竟是什么问题.这是一个学说错误吗？为什么启用OpCache导致Doctrine异常并将其关闭工作正常？我是否遗漏了配置部分或实体中的内容？
