在我的控制器中,我得到这样的.@H_403_2@

public function getEntityManager()
{
    if(null === $this->em){
        $this->em = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default');
    }
    return $this->em;
}

public function setEntityManager(EntityManager $em)
{
    $this->em = $em;
}

但是在插件类中,我在$this-> getServiceLocator()行上收到错误.因为这在插件类中不可用.@H_403_2@

我怎样才能这样做,以便我可以获取一些记录并在插件中插入少量数据库.@H_403_2@

我的插件类中有MvcEvent $e对象,我可以利用它来获取实体管理器吗？@H_403_2@

我用this plugin来创建我的插件@H_403_2@

任何指南都会受到关注.@H_403_2@

我在module.PHP中调用了上面的类@H_403_2@

public function onBootstrap(Event $e) 
    {

        $application = $e->getApplication();        
        $services    = $application->getServiceManager();        

        $eventManager = $e->getApplication()->getEventManager();
        $eventManager->attach('dispatch',array($this,'loadConfiguration'),101);

    }

public function loadConfiguration(MvcEvent $e)
    {

        $e->getApplication()->getServiceManager()
                  ->get('ControllerPluginManager')->get('AclPlugin')
                  ->checkAcl($e); //pass to the plugin...      

    }

我在module.config.PHP中注册了这个插件@H_403_2@
