ZF2 - Doctrine2 MongoDB ODM - “在链配置命名空间中找不到该类”

我经常在这里看到同样的错误，并且已经通读并根据之前的问题和答案进行了更改，但无济于事。

我已经通过Composer安装了Doctrine的Mongo ODM和Zend Framework，并完成了安装，如下所述

https://github.com/doctrine/DoctrineMongoODMModule

我已经修改了我的/config/autoload/module.doctrine-mongo-odm.local.php 文件，超出了上述文档的建议，以解决我的问题并基于此处类似问题的答案，因此它现在如下所示

<?php
return array(
    'doctrine' => array(
        'connection' => array(
            'odm_default' => array(
                'server'    => 'removed.mongolab.com',

                'options'   => array()
            ),
        ),
        'configuration' => array(

        ),
        'odm_default' => array(
            'drivers' => array(
                'Application'Document' => 'odm_driver'
            )
        ),
        'odm_driver' => array(
            'class' => 'Doctrine'ODM'MongoDB'Mapping'Driver'AnnotationDriver',
            'cache' => 'array',
            'paths' => array(
                'module/Application/src/Application/Document'
            ),
        ),
        'documentmanager' => array(
            'odm_default' => array(
                'connection'    => 'odm_default',
                'configuration' => 'odm_default',
                'eventmanager' => 'odm_default'
            )
        ),
        'eventmanager' => array(
            'odm_default' => array(
                'subscribers' => array()
            )
        ),
    ),
);

我有一个文件/模块/应用程序/src/应用程序/文档/用户.php如下所示

<?php
namespace Application'Document;
use Doctrine'ODM'MongoDB'Mapping'Annotations;
class User {
    /** @ODM'Id */
    private $id;
    /** @ODM'Field(type="bin_data_timestamp") */
    private $timestamp;
    /** @ODM'Field(type="string") */
    private $username;
    /** @ODM'Field(type="bin_data_md5") */
    private $password;
    /** @ODM'Field(type="bin_data_uuid") */
    private $salt;
    /** @ODM'Field(type="string") */
    private $realName;
    /** @ODM'Field(type="string") */
    private $email;
    public function getId() {
        return $this->id;
    }
    // ...
    public function setId($id) {
        $this->id = $id;
    }
    // ...
}

在我的控制器中，我使用以下代码。

$dm = $this->getServiceLocator()->get('doctrine.documentmanager.odm_default');
$user = new User;
$user->setUsername("test");
$dm->persist($user);
$dm->flush();

但是，我遇到了臭名昭著的错误

The class 'Application'Document'User' was not found in the chain configured namespaces 

任何协助将不胜感激。
