问题

I've been searching forever to solve my problem. But I can't find any solution.

I always get this error message when I try to open the homepage:

Uncaught exception 'Doctrine\Common\Persistence\Mapping\MappingException' with message 'The class 'Test\Bundle\UserBundle\Entity\User' was not found in the chain configured namespaces ' in...

The weird thing is that I only get it when I have following URL:

http://localhost/

But when I run it on this URL I don't get any error and my page is being displayed correctly:

http://localhost/app_dev.php

My Configuration looks like this (config.yml):

# Doctrine Configuration
dbal:
  default_connection: default
  connections:
    default:
      driver:   "%database_driver%"
      host:     "%database_host%"
      port:     "%database_port%"
      dbname:   "%database_name%"
      user:     "%database_user%"
      password: "%database_password%"
      charset:  UTF8
    test:
      driver:   "%database_driver2%"
      host:     "%database_host2%"
      port:     "%database_port2%"
      dbname:   "%database_name2%"
      user:     "%database_user2%"
      password: "%database_password2%"
      charset:  UTF8
orm:
  default_entity_manager: default
  entity_managers:
    default:
      connection: default
      mappings:
        TestUserBundle:
          type: annotation

And I call Doctrine in my custom service like this:

public function __construct(EntityManager $em)
{
    $repositiory = $em->getRepository('Test\Bundle\UserBundle\Entity\User');
    $this->user = $repositiory->find($_SERVER['AUTH_USER']);
}

My Symfony Application is running on an IIS Webserver.

Do you guys know where I made a mistake?

回答1:

Mapping name is TestUserBundle but the path is Test\Bundle\User\Bundle, shouldn't it be named TestBundleUserBundle instead? Also, usually the mappings and auto_generate_proxy_classes are set to true in dev mode which might explain why it's working there and not in prod.

You might want to checkout the documentation (Symfony 2.7) which shows how exactly you should be configuring the mappings depending on your case.

Custom Mapping Entities in a Bundle

doctrine:
    # ...
    orm:
        # ...
        auto_mapping: true
        mappings:
            # ...
            AppBundle:
                type: xml
                dir: SomeResources/config/doctrine

Mapping Entities Outside of a Bundle

doctrine:
    # ...
    orm:
        # ...
        mappings:
            # ...
            SomeEntityNamespace:
                type: annotation
                dir: "%kernel.root_dir%/../src/Entity"
                is_bundle: false
                prefix: App\Entity
                alias: App

Last, but not least, always clear your cache directory after applying changes to the config.yml or files in the app/config/ directory.

As mentioned in the comments: You need to temporarily stop any PHP processes that might be using the prod directory (i.e. if you've ran console server:run) and try again. If that doesn't do it, try this
