我的数据库连接有问题。我想创建一个服务作为专辑howto。当我创建服务时，ZF2给我一个错误：

/module/Firewall/Module.php

namespace Firewall;

use Zend\Mvc\ModuleRouteListener,
    Zend\Mvc\MvcEvent,
    Firewall\Model\UserTable;

class Module
{
    // ...
    public function getServiceConfiguration()
    {
        return array(
        'factories' => array(
            'user-table' => function($sm) {
                $dbAdapter = $sm->get('db-adapter');
                $table = new UserTable($dbAdapter);
                return $table;
            },
        ),
        );
    }
}

/module/Application/Module.php

namespace Application;

use Zend\Mvc\ModuleRouteListener;
use Zend\Mvc\MvcEvent;
use Zend\Db\Adapter\Adapter as DbAdapter;

class Module
{
    public function getServiceConfiguration()
    {
        return array(
            'factories' => array(
                'db-adapter' => function($sm) {
                    $config = $sm->get('config');
                    $config = $config['db'];
                    $dbAdapter = new DbAdapter($config);
                    return $dbAdapter;
                },
            ),
        );
    }
}

/module/Application/config/autoload/global.php

return array(
    'db' => array(
        'driver' => 'Pdo',
        'dsn' => 'mysql:dbname=firewall;hostname=localhost',
        'username' => 'aaaaaa',
        'password' => 'aaaaaa',
        'driver_options' => array(
            PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
        ),
    ),
);

我在控制器中的电话：

if (!$this->userTable) {
            $sm = $this->getServiceLocator();
            $this->userTable = $sm->get('user-table');
        }
        return $this->userTable;

非常感谢你的帮助......我被阻止了..：/

Answer 1

尝试使用：

public function getServiceConfig() //instead of getServiceConfiguration()

Answer 2

我认为问题是您尝试使用服务来配置global.php中的Db环境，但您编写代码的方式不是在global.php中使用服务管理器。

尝试将全局更改为此，因为您正在使用服务管理器和工厂数据库。

 return array(
'service_manager' => array(
    'factories' => array(
        'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
    ),
),
    'db' => array('driver' => 'Pdo',
    'dsn' => 'mysql:dbname=firewall;host=localhost;charset=utf8',
    'user' => 'root', 'pass' => 'aaaa' ),
     'driver_options' => array(
        PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''       
),

）;

找不到ZF2服务数据库适配器
