奇怪的是，我只有在我有以下 URL 时才能得到它:

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

http://localhost/

但是当我在这个 URL 上运行它时，我没有收到任何错误，并且我的页面正在正确显示:

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

我的配置看起来像这样(config.yml):

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

我在我的自定义服务中这样调用 Doctrine:

And I call Doctrine in my custom service like this:

public function __construct(EntityManager $em)
{
    $repositiory = $em->getRepository('TestBundleUserBundleEntityUser');
    $this->user = $repositiory->find($_SERVER['AUTH_USER']);
}

我的 Symfony 应用程序正在 IIS Web 服务器上运行.

My Symfony Application is running on an IIS Webserver.

你们知道我哪里做错了吗?

Do you guys know where I made a mistake?

推荐答案

映射名称是 TestUserBundle 但路径是 TestBundleUserBundle，不应该它被命名为 TestBundleUserBundle 吗?此外，通常 mappings 和 auto_generate_proxy_classes 在开发模式下设置为 true，这可能解释了为什么它在那里工作而不是在 prod 中工作.

Mapping name is TestUserBundle but the path is TestBundleUserBundle, 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.

您可能想查看 documentation (Symfony 2.7) 它显示了你应该如何根据你的情况来配置映射.

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

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

映射包外的实体

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

最后但同样重要的是，在将更改应用到 config.yml 或 app/config/ 目录中的文件后，请务必清除缓存目录.

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

正如评论中提到的:您需要暂时停止任何可能正在使用 prod 目录的 PHP 进程(即，如果您已经运行了控制台服务器:运行)并重试.如果还不行，试试 这个

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
