Path 如何在Zf2中重用服务层？

我的a模块有一个服务层。现在我想通过从另一个模块B调用它来重用服务层。我知道我必须将我的服务层注入模块B的控制器中

我的问题是如何给出模块B的服务层路径

在模块B的控制器工厂中，$serviceLocator->get（'A\Service\AService'），并在控制器中使用A\Service\AService；这些将不起作用，因为这些是模块A的目录位置。而且，默认路径似乎从控制器外部的文件夹开始。我如何为B使用这些路径

class IndexController extends AbstractActionController
{
    function __construct(AService $sm) {

    $this->sm =$sm;
    }

    public function indexAction()
    {

            $event = $this->getEvent();
            $request = $event->getRequest();
            $router = $event->getRouter();
            $uri = $router->getRequestUri();
            $baseUrl = sprintf('%s://%s%s', $uri->getScheme(), $uri->getHost(), $request->getBaseUrl());

    $this->sm->callMethod($baseUrl);

    }
}

My module.config.php

return array(

 'controllers' => array(
        'factories' => array(
            'Application\Controller\IndexController' => 'Application\Controller\IndexControllerFactory',
        ),
    ),

在module.php中

    public function getControllerConfig()
{
return array(
    'factories' => array(
        'Application\Controller\Index' => function ($sm){
            $a = $sm->getServiceLocator()->get('A\Service\AService');

            return new Application\IndexController($a);
        }
    ),
);
}

它的工作原理应该与在控制器中使用服务相同

我假设您在模块A中注册了服务

...
'invokables'   => array(
    'A\Service\AService' => 'A\Service\AService',
)
...

从那时起，您可以在任何模块中使用它（例如，在您的B modulemodule.php）：

代码应该可以工作，所以你能复制粘贴它吗？请检查你答案的注释。我还添加了一些代码。我按照您的建议进行了更改。我得到错误“参数1传递给Application\Controller\IndexController:：\uu construct（）必须是\Service\AService的实例”。我为我的IndexController添加了代码。任何帮助都将不胜感激。谢谢错误是自我解释的。请。从module config复制粘贴代码的一部分，将实例传递给控制器的构造函数。呃，我指的是我建议的唯一一个执行“getControllerConfig（）”的部分？？您的module.config.php乱七八糟。只需删除controllers=>factory和controllers=>invokables。您正在模块中执行此操作。phpIt工作正常。谢谢！：）只是一个初学者，尝试了不同的东西，却忘了改变它。

public function getControllerConfig()
{
    return array(
        'factories' => array(
            'B\Controller\Index' => function ($sm){
                $a = $sm->getServiceLocator()->get('A\Service\AService');

                return new B\IndexController($a);
            }
        ),
    );
}
