当我尝试在 ZF2 中使用学说 2 时，出现以下错误。

Zend\ServiceManager\ServiceManager::get 无法获取或创建理论.entitymanager.orm_default 的实例

【问题讨论】：

数据库连接详细信息是否正确？
很难说你为什么会在没有更多上下文的情况下得到这个错误。请显示您收到此错误的工厂代码和您的 application.config.php
是的，对不起，我昨天得赶时间，所以我不能添加一些源代码。现在我添加了它。
请将所有堆栈跟踪添加到您的帖子中
也是您的application.config.php 的modules 键

标签： php doctrine-orm zend-framework2

【解决方案1】：

第一个麻烦是你的配置加载器。您已将其修改为包含：

    'config_glob_paths' => [
        'config/autoload/local/{,*.}local.php',
        'config/autoload/global/{,*.}global.php'
    ],

但是您的文件夹设置为：

config/autoload/global/doctrine.php

所以加载器不会匹配。

此全局路径适用于您的文件结构：

    'config_glob_paths' => [
        'config/autoload/local/{,*.}php',
        'config/autoload/global/{,*.}php'
    ],

作为替代方案，我上传了一个更“标准”的配置设置，可以帮助您：

https://github.com/Saeven/doctrine-error/tree/master/src/config

不过，简而言之，您遇到了严重错误，因为无法建立连接，仅仅是因为您的数据库详细信息不存在（因为您的配置加载器已被冲洗）。

其次，看起来您的 composer.json 正在加载一些不兼容的项目。我使用了我维护的项目中的一个，并结合了加载程序修复程序，当我输入有效的数据库凭据时，我看到了“测试”：

composer.json

【讨论】：

嘿 Saeven，确实我的 autload 目录的配置是错误的。但这不是主要问题。正如你所说，composer.json 文件已经加载了一些不兼容的项目，但我真的不明白为什么？没关系，有了您所需的物品，一切正常！非常感谢您抽出宝贵的时间，克隆我的仓库等...
这是我的荣幸，嘿，我会为了一个好的赏金做任何事！ ;) 祝 ZF2 好运—— ZF3 也即将到来！另外，我在您的骨架中注意到您遇到了 ServiceLocator 警告。我有一篇博文可能对您有所帮助：circlical.com/blog/2016/3/9/preparing-for-zend-f
谢谢，但是以这种方式调用服务定位器只是为了显示错误。我通常不这样做:)
没有问题，不过请查看惰性工厂——这很有帮助！你想让我修改我的答案来锁定赏金吗？ ;)

【解决方案2】：

我认为您的问题出在您的工厂以及如何获得 EntityManager。

这是在 ZF2 工厂中如何从 serviceLocator 获取 Doctrine\ORM\EntityManager 的方法：

class YourFactory implements FactoryInterface  
{

    public function createService(ServiceLocatorInterface $serviceLocator) 
    {            
        /* @var $em \Doctrine\ORM\EntityManager */
        $em = $serviceLocator->getServiceLocator()->get('em');

        // $em contains methods to get repo, etc ...

        // injections here
        $obj = new Obj();
        $obj->setEntityManager($em);

        return $obj;
    }

}

试试看告诉我

【讨论】：

不，这不是问题所在。实体管理器的注册服务名称为doctrine.entitymanager.orm_default，Doctrine\ORM\EntityManager应该是该服务的别名。
你能在这里帮助一个 ZF2 菜鸟吗？我不知道我应该把这个工厂文件放在哪里，以及如何告诉 ZF2 加载它。你能补充一点吗？
@JohnYeates 这个工厂（虚拟）就是一个例子。任何工厂都必须在服务管理器中通过配置文件在factories 部分中声明。请阅读文档framework.zend.com/manual/2.4/en/modules/…
