将一个命名空间添加到已配置的EntityManager中 [英] Add a namespace to an already configured EntityManager

问题描述

我有一个EntityManager实例完全配置和工作。问题是如何向这个EM添加一个额外的命名空间？

  $ em-> getConfiguration（） - > addEntityNamespace 'MyGreatBundle'，'My\GreatBundle\Entity'）; 
  

这不工作，抛出如下：

Doctrine\Common\Persistence\Mapping\MappingException：在链配置的命名空间中找不到类My\GreatBundle\Entity\User

解决方案

我设法解决了这个问题，不得不添加驱动程序：

  $ namespace ='My\GreatBundle\Entity'; 
 $ configuration = $ em-> getConfiguration（）; 
 $ annotationDriver = new AnnotationDriver（
 $ this-> container-> get（'annotation_reader'），
 [__DIR__。'/../Entity'] 
） ; 
 
 / ** @var MappingDriverChain $ driver * / 
 $ driver = $ configuration-> getMetadataDriverImpl（）; 
 $ driver-> addDriver（$ annotationDriver，$ namespace）; 
 
 $ configuration-> addEntityNamespace（'MyGreatBundle'，$ namespace）; 
  

I've got an EntityManager instance fully configured and working. The question is how to add an additional namespace to this EM?

$em->getConfiguration()->addEntityNamespace('MyGreatBundle', 'My\GreatBundle\Entity');

This does not work, throws the following:

Doctrine\Common\Persistence\Mapping\MappingException: The class 'My\GreatBundle\Entity\User' was not found in the chain configured namespaces

解决方案

I managed to fix this issue, had to add the driver too:

$namespace = 'My\GreatBundle\Entity';
$configuration = $em->getConfiguration();
$annotationDriver = new AnnotationDriver(
    $this->container->get('annotation_reader'),
    [__DIR__ . '/../Entity']
);

/** @var MappingDriverChain $driver */
$driver = $configuration->getMetadataDriverImpl();
$driver->addDriver($annotationDriver, $namespace);

$configuration->addEntityNamespace('MyGreatBundle', $namespace);
