zend 2：試圖通過'適配器'鍵在local.php中指定備用數據庫

Question

我試圖讓一個特定的模塊連接到不同的數據庫。 [我已經問] [1]如何做到這一點，並提供了[此鏈接] [2]。

它不是非常複雜，但它看起來像我做錯了，因爲我看到一個ServiceNotCreatedException。

這裏是我的配置/自動加載/ local.php的樣子：

return array(
     'db' => array(
      //Override global.php 'dsn' to specify local port on dev box 
      'dsn' => 'mysql:dbname=zf2tutorial;host=localhost;port=3307', 
      'username' => 'root', 
      'password' => 'pass!', 
      'adapters' => array(
       'testdb' => array(
        'dsn' => 'mysql:dbname=otherdb;host=testsrv', 
        'username' => 'root', 
        'password' => 'pass', 
       ) 
      ) 
     ), 
    ); 


Now here is what I have the module's Module.php: 

public function getServiceConfig() { 
    return array(
     'factories' => array(
      'Helpdesk\Model\TicketTable' => function($sm) { 
       $tableGateway = $sm->get('TicketTableGateway'); 
       $table = new TicketTable($tableGateway); 
       return $table; 
      }, 
      'TicketTableGateway' => function($sm) { 
       $dbAdapter = $sm->get('testdb'); 
       $resultSetPrototype = new ResultSet(); 
       $resultSetPrototype->setArrayObjectPrototype(
        new Ticket()); 
       return new TableGateway('ticket', $dbAdapter, null, 
        $resultSetPrototype); 
      }, 
     ), 
    ); 
} 

這裏是控制器的方法：

namespace Helpdesk\Controller; 

use Zend\Mvc\Controller\AbstractActionController; 
use Zend\View\Model\ViewModel; 

use Helpdesk\Model\Ticket; 

class HelpdeskController extends AbstractActionController { 
    protected $ticketTable; 

    public function indexAction() { 
     return new ViewModel(array(
      'tickets' => $this->getTicketTable()->fetchAll() 
     )); 
    } 

我使用的是TableGateway以同樣的方式[zend教程] [3]。 我這樣做：

$dbAdapter = $sm->get('testdb'); 

取而代之的是：

$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter'); 

我誤解這個工程？

編輯： 這裏是堆棧跟蹤：

An exception was raised while creating "Helpdesk\Model\TicketTable"; no instance returned 

App\vendor\zendframework\zendframework\library\Zend\Mvc\Controller\AbstractController.php(117): Zend\EventManager\EventManager->trigger('dispatch', Object(Zend\Mvc\MvcEvent), Object(Closure)) 
App\vendor\zendframework\zendframework\library\Zend\Mvc\DispatchListener.php(114): Zend\Mvc\Controller\AbstractController->dispatch(Object(Zend\Http\PhpEnvironment\Request), Object(Zend\Http\PhpEnvironment\Response)) 
[internal function]: Zend\Mvc\DispatchListener->onDispatch(Object(Zend\Mvc\MvcEvent)) 
App\vendor\zendframework\zendframework\library\Zend\EventManager\EventManager.php(468): call_user_func(Array, Object(Zend\Mvc\MvcEvent)) 
App\vendor\zendframework\zendframework\library\Zend\EventManager\EventManager.php(207): Zend\EventManager\EventManager->triggerListeners('dispatch', Object(Zend\Mvc\MvcEvent), Object(Closure)) 
App\vendor\zendframework\zendframework\library\Zend\Mvc\Application.php(309): Zend\EventManager\EventManager->trigger('dispatch', Object(Zend\Mvc\MvcEvent), Object(Closure)) 
App\public\index.php(17): Zend\Mvc\Application->run() 
{main}

我不知道你的方法，但我需要在我的項目二級分貝所以這是我做過什麼：

配置：

'mail_db' => array(
    'driver' => 'Pdo_Mysql', 
    'database' => 'iptcms_mail', 
    'hostname' => 'localhost', 
    'driver_options' => array(
     PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'' 
    ), 
    'username' => 'root', 
    'password' => '', 
), 

廠：

namespace Mail\Factory; 

use Zend\ServiceManager\FactoryInterface; 
use Zend\ServiceManager\ServiceLocatorInterface; 

class DbAdapter implements FactoryInterface{ 
    public function createService(ServiceLocatorInterface $serviceLocator) { 
     $config = $serviceLocator->get('Config'); 
     $adapter = new \Zend\Db\Adapter\Adapter($config['mail_db']); 
     return $adapter; 
    } 
} 

和工廠配置：

'service_manager' => array(
    'factories' => array(
     'mail_db_adapter' => 'Mail\Factory\DbAdapter', 
    ), 
), 

如果你不能找出如何解決這個問題，你可以不喜歡這樣。
