Zend Framework 2和Doctrine 2 - 多个数据库的配置 [英] Zend Framework 2 and Doctrine 2 - Configuration for multiple databases

问题描述

我将代码从configuration.md文件粘贴到

I pasted the code from the configuration.md file to

module.config.php

        ),
    );
}

我收到以下错误：

C:\xampp\vhosts\zf2-trade\vendor\zendframework\zendframework\library\Zend\ServiceManager\ServiceManager.php:529

消息：

Zend\Mvc\Controller\PluginManager::get was unable to fetch or create an instance for getServiceManager

我做错了什么？请帮助。

What am I doing wrong? Please help.

推荐答案

Mac，欢迎来到stackoverflow ！您不需要为每个连接分别定义自定义工厂。 DoctrineORMModule 已经为我们处理了这份工作。

Mac, welcome to stackoverflow! You don't need to define custom factories for each connection respectively. DoctrineORMModule already handles this job for us.

当您需要实体经理，通过在别名中使用他们的名字从服务定位器实例中获取它：

When you need the entity managers, get it from service locator instance by using their names in the alias like this:

$this->getServiceLocator()->get('doctrine.entitymanager.orm_default');

或

$this->getServiceLocator()->get('doctrine.entitymanager.orm_alternative');

我正在共享我目前使用的一个当前应用程序的数据库配置，目前使用的是PostgreSQL和MySQL连接。 / p>

I'm sharing one of my current application's database configuration which currently uses both PostgreSQL and MySQL connections.

<?php
return array(
    'doctrine' => array(
        'connection' => array(
            // Default DB connection
            'orm_default' => array(
                'driverClass' => 'Doctrine\DBAL\Driver\PDOPgSql\Driver',
                'params' => array(
                    'host' => '1.2.3.4',
                    'user' => 'pdbuser',
                    'port' => '5432',
                    'password' => '****',
                    'dbname' => 'mydb',
                    'driver' => 'pdo_pgsql',
                ),
            ),

            // Alternative DB connection
            'orm_alternative' => array(
                'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
                'params' => array(
                    'host' => '4.5.6.7',
                    'user' => 'dbuser',
                    'port' => '3306',
                    'password' => '****',
                    'dbname' => 'mydb',
                    'driver' => 'pdo_mysql',
                ),
            ),
        ),

        // Entity Manager instantiation settings
        'entitymanager' => array(
            'orm_default' => array(
                'connection'    => 'orm_default',
                'configuration' => 'orm_default',
            ),
            'orm_alternative' => array(
                'connection'    => 'orm_alternative',
                'configuration' => 'orm_alternative',
            ),
        ),

        // Use array cache locally, also auto generate proxies on development environment.
        'configuration' => array(
            'orm_default' => array(
                'metadata_cache' => 'array',
                'query_cache' => 'array',
                'result_cache' => 'array',
                'hydration_cache' => 'array',
                'generate_proxies' => true,
            ),
            'orm_alternative' => array(
                'metadata_cache' => 'array',
                'query_cache' => 'array',
                'result_cache' => 'array',
                'hydration_cache' => 'array',
                'generate_proxies' => true,
            ),
        ),
    ),
);

您可以轻松地将此配置与您的合并。

You can easily merge this configuration with yours.
