我正在开发一个ZF2系统并且它运行良好，但在我在其他计算机中克隆存储库之后，这个已弃用的错误已经出现：
您正在从Module \ Controller \ Controller类中检索服务定位器。请注意，ServiceLocatorAwareInterface已弃用，将在3.0版中与ServiceLocatorAwareInitializer一起删除。您需要更新您的类以在创建时接受所有依赖项，通过构造函数参数或setter，并使用工厂执行注入。在第258行的/home/path/project/vendor/zendframework/zend-mvc/src/Controller/AbstractController.php

我在控制器中检索服务时出现错误（扩展Zend \ Mvc \ Controller \ AbstractActionController）：
"require": {
"php": ">=5.5",
"ext-curl": "*",
"ext-json": "*",
"ext-mbstring": "*",
"zendframework/zendframework": "~2.5",
"doctrine/doctrine-orm-module": "0.*",
"hounddog/doctrine-data-fixture-module": "0.0.*",
"imagine/Imagine": "~0.5.0"
在Zend \ Mvc \ Controller \ AbstractController的Zend核心中是这样的：
$this->getServiceLocator()->get("Module\Service\Service");
之前只有这个：
public function getServiceLocator()
{
trigger_error(sprintf(
'You are retrieving the service locator from within the class %s. Please be aware that '
. 'ServiceLocatorAwareInterface is deprecated and will be removed in version 3.0, along '
. 'with the ServiceLocatorAwareInitializer. You will need to update your class to accept '
. 'all dependencies at creation, either via constructor arguments or setters, and use '
. 'a factory to perform the injections.',
get_class($this)
), E_USER_DEPRECATED);
return $this->serviceLocator;
}
我已经尝试了一切，有人知道我该做什么吗？

您无需执行任何操作，尚未。升级到ZF3时，您必须更改控制器类接收其依赖项的方式。
ZF2支持两种依赖注入模式：服务定位器和构造函数。 ZF3删除“按服务位置”并且需要“通过构造函数”。实际上，这一切确实改变了依赖关系如何解决，将解决方案从“及时”转移到“建设中”。
而不是从任何地方获取服务，而是在构建接收它们。按以下方式更新您的代码：
namespace Module\Controller;
class Controller {
public function __construct(\Module\Service\Service $service) {
$this->service = $service;
}
}
在课程方法中使用$this->service所需的位置。
然后使用控制器工厂来创建控制器，如下所示：
function ($controllers) {
$services = $controllers->getServiceLocator();
return new \Module\Controller\Controller($services->get('Module\Service\Service'));
}
Issue 5168中讨论了此更改，this blog post讨论了服务注册服务注入为反模式的原因。

你可以创建一个控制器插件 service（）（但这是一个不好的做法，更喜欢FactoryInterface）

'service' => YourNamespace\Mvc\Controller\Plugin\Service\ServiceFactory::class,

{
/**

*/
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{

$plugin->setServiceLocator($container);
