Zend Framework 2 和 Doctrine 2 - 多个数据库的配置

Question

我将configuration.md文件中的代码粘贴到

模块.config.php

'doctrine' => array(
        'connection' => array(
            'orm_crawler' => array(

    ),

Module.php

    public function getServiceConfig()

                    'doctrine.mapping_collector.orm_crawler'      => function (\Zend\ServiceManager\ServiceLocatorInterface $sl) {
                        $em = $sl->get('doctrine.entitymanager.orm_crawler');
    
                        return new \DoctrineORMModule\Collector\MappingCollector($em->getMetadataFactory(), 'orm_crawler_mappings');
                    },
                    'DoctrineORMModule\Form\Annotation\AnnotationBuilder' => function(\Zend\ServiceManager\ServiceLocatorInterface $sl) {
                        return new \DoctrineORMModule\Form\Annotation\AnnotationBuilder($sl->get('doctrine.entitymanager.orm_crawler'));
                    },
            ),
        );
    }

I'm getting the following error:

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

Message:

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

What am I doing wrong?

Answer 1

您不需要分别为每个连接定义自定义工厂。 DoctrineORMModule 已经为我们处理了这项工作。

当您需要实体管理器时，请通过在别名中使用它们的名称从服务定位器实例中获取它，如下所示：

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

或

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

我正在分享我当前应用程序的数据库配置之一，该配置当前同时使用 PostgreSQL 和 MySQL 连接。

<?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配置合并。

Answer 2

@edigu 答案工作得很好，但在某些情况下，它给出了 “以下错误：Zend\ServiceManager\ServiceManager:: get 无法获取或创建Document.connection.orm_crawle 的实例”

因此，为了解决此问题，我们可以更改实体管理器设置

'entitymanager' => array(
        'orm_default' => array(
            'connection'    => 'orm_default',
            'configuration' => 'orm_default',
        ),
        'orm_alternative' => array(
            'connection'    => 'orm_alternative',
            'configuration' => 'orm_default',  //<--use parent configurations 
        ),
    ),

@foozy：这正是我正在寻找的。与

./vendor/bin/doctrine-module orm:schema-tool:update --force

您现在可以更新或创建数据库架构。
