Question

我想在我的模型中访问全局配置文件中的数据库配置集。在ZF2控制器中，我们可以使用getServiceLocator方法加载配置，但是如何在我的Model类中执行此操作？这是我的Model类：

class BaseModel extends AbstractTableGateway
{
    public function __construct()
    {
        $this->adapter = new Adapter(array(
            'driver' => 'Pdo_Mysql',
            'database' => 'mydbname',
            'username' => 'root',
            'password' => 'root'
        ));
    }
}

我只想加载'db'数组配置（位于全局配置文件中）并将此输入数组替换为Adapter类输入参数。

这是我的全局配置文件：

return array(

    "db" => array(
        "driver" => "Pdo_Mysql",
        "dsn" => "mysql:dbname=mydbname;host=localhost",
        "username" => "root",
        "password" => "root"
    ),

    "service_manager" => array(
        "factories" => array(
            "dbFactory" => "Zend\Db\Adapter\AdapterServiceFactory",
        )
    )

);

如果您需要修改DbAdapter配置（您要连接的数据库），您需要创建一个不同的适配器实例，然后注入适配器进入你的模型＆＃39;

class FooModel extends AbstractTableGateway
{
    public function __construct($dbAdapter)
    {
        $this->adapter = $adapter;
    }
}

然后创建适配器服务工厂

public function getServiceConfig()
{
   return array(
       'factories' => array(

           // Standard database adapter
           'dbAdapter1' => function($sm) {
              $config = $sm->get('config');
              return new \Zend\Db\Adapter\Adapter($config['db']);
           }, 
           // Another db adapter using different config
           'dbAdapter2' => function($sm) {
              $config = $sm->get('config');
              return new \Zend\Db\Adapter\Adapter($config['db2']);
           }, 

           // The model that requires a different database
           // adapter to be injected
           'FooModel' => function($sm) {
              $adapter = $sm->get('dbAdapter2');
              return new Model\FooModel($adapter);
           }, 

       ),
   );
}

然后，您可以将全部配置添加到全局或db2中的module.config.php键。
