Question

我挣扎了几天这个问题，但仍然没有发现它的问题。

这是application.config.php中的配置段：

// Initial configuration with which to seed the ServiceManager.
// Should be compatible with Zend\ServiceManager\Config.
'service_manager' => array(
    'abstract_factories' => array(
        'Zend\Log\LoggerAbstractServiceFactory',
        'Zend\Cache\Service\StorageCacheAbstractServiceFactory',
    )
),

'log' => array(
    'Log\App' => array(
        'writers' => array(
            array(
                'name' => 'stream',
                'priority' => 1000,
                'options' => array(
                    'stream' => 'data/logs/app.log'
                )
            )
        )
    )
)

我尝试在我的控制器中获取服务实例：

$logger = $this->getServiceLocator()->get('Log\\App');

抛出异常：

An error occurred
An error occurred during execution; please try again later.

更新感谢您的帮助 ocramius

我将段移动到module.config.php，这次抛出异常：

Zend\ServiceManager\Exception\ServiceNotCreatedException
File:
/var/openresty/html/skeleton-zf2/vendor/zendframework/zendframework/library/Zend/ServiceManager/ServiceManager.php:1070
Message:
An abstract factory could not create an instance of applicationweb(alias: Application\Web).

正如在IRC上所讨论的，这里的问题是2：

您拥有此配置的文件是config/application.config.php（不是模块/合并配置，但是投入使用的内容"ApplicationConfig"）
由于异常，抽象工厂无法实例化服务。为了调试异常，您可以执行以下操作：

try {
    // ...
    $logger = $this->getServiceLocator()->get('Log\\App');
    // ...
} catch (\Exception $e) {
    do {
        var_dump($e->getMessage());
    } while ($e = $e->getPrevious());
}

最有可能的情况是，您的配置对于必须由日志编写者访问的文件有一个错误的路径，并且会通过跟踪这些异常来实现，就像我刚刚显示的那样。
