迁移后为什么停止工作水化器zf2-> zf3？

Question

我不明白为什么停止工作AggregateHydrator如果在映射器工厂得到它：返回

$aggregatehydrator = $container->get(AggregateHydrator::class); 

空的对象。我试着调试和PHP正在死去（多余的内存），当我尝试：

\Zend\debug\debug::dump($aggregatehydrator); 

如果我水化另一种方式：

$tagsHydrator = $container->get(TagsHydrator::class); 
$categoryHydrator = $container->get(CategoryHydrator::class); 
$postHydrator = $container->get(PostHydrator::class); 
$datesHydrator = $container->get(DatesHydrator::class); 
$aggregatehydrator = new  \Zend\Hydrator\Aggregate\AggregateHydrator(); 
$aggregatehydrator->add($postHydrator); 
$aggregatehydrator->add($categoryHydrator); 
$aggregatehydrator->add($tagsHydrator); 
$aggregatehydrator->add($datesHydrator); 

它工作一切。填充的对象被返回。

class AggregateHydratorFactory implements FactoryInterface 
{ 
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null) 
    { 
     $aggregatehydrator = new AggregateHydrator(); 

     $tagsHydrator = $container->get(TagsHydrator::class); 
     $categoryHydrator = $container->get(CategoryHydrator::class); 
     $postHydrator = $container->get(PostHydrator::class); 
     $datesHydrator = $container->get(DatesHydrator::class); 


     $aggregatehydrator->add($postHydrator); 
     $aggregatehydrator->add($categoryHydrator); 
     $aggregatehydrator->add($tagsHydrator); 
     $aggregatehydrator->add($datesHydrator); 

     return $aggregatehydrator; 
    } 
} 

Answer 1

我AggregateHydratorFactory补充说：

$aggregatehydrator = new AggregateHydrator(); 
    $aggregatehydrator->setEventManager($container->get('EventManager'));
