Symfony错误在链配置的命名空间XXX中找不到类XXX [英] Symfony error The class XXX was not found in the chain configured namespaces XXX

问题描述

这个问题还有一些其他的问题，但没有一个是非常有帮助的。我是Symfony的新手，所以很难让我的头脑。

There are some other questions on this subject already, but none of them were really helpful. I am new to Symfony, so it's pretty hard to get my head around it.

我在文件Client\IntranetBundle\LDAP\LDAPAuthenticationProvider.php中，此代码导致错误：

I am in the file Client\IntranetBundle\LDAP\LDAPAuthenticationProvider.php and this code is causing an error:

$user = new LDAPUser($username);

我添加了它的命名空间是：

I did add it's namespace which is:

use Client\IntranetBundle\LDAP\LDAPUser;

LDAPUser实现UserInterface

LDAPUser implements UserInterface

错误I get是

The class 'Client\IntranetBundle\LDAP\LDAPUser' was not found in the chain
configured namespaces Client\ClientBundle\Entity

这是什么意思？从我读到的，它与映射有关。

What is that suppose to mean? From what I read it has something to do with the mapping.

我的Doctrine orm在config.yml中设置为：

My Doctrine orm in the config.yml is set to:

 orm:
    auto_generate_proxy_classes: %kernel.debug%
    auto_mapping: true

希望您能帮助我。

编辑＃1 ：

实际上，我发现它不是

$user = new LDAPUser($username);

这是导致错误，但是当我试图保留这个实体时：

That is causing the error, but it is when I am trying to persist this entity:

$entityManager->persist($user);

编辑＃2：

我对映射有什么问题感到困惑：

I'm confused with what's wrong with the mapping:

<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
                http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">

<entity name="Client\IntranetBundle\LDAP\LDAPUser" table="users" repository-class="Client\ClientBundle\Repository\UserRepository">
    <id name="id" type="integer" column="id">
        <generator strategy="AUTO" />
    </id>
    <field name="username" column="username" type="string" length="100" />
</entity>

也许是因为我在两束之间跳转？

Maybe it's because I'm jumping between two bundles?

推荐答案

默认情况下， auto_mapping 对于 Entity 命名空间下的实体，所以鉴于您的实体不在，Doctrine不了解任何内容。

By default, the auto_mapping feature looks for entities under the Entity namespace, so given that your entity is not there, Doctrine does not know anything about it.

您需要将您的实体放在 Entity 命名空间下，或手动配置Doctrine以添加自定义实体命名空间。这样你就会丢失 auto_mapping 功能，所以您需要手动注册每个软件包：

You need to put your entity under the Entity namespace or configure Doctrine by hand to add your custom entity namespace. This way you lose the auto_mapping feature, so you would need to register every bundle manually:

orm:
    auto_generate_proxy_classes: %kernel.debug%
    entity_managers:
        default:
            mappings:
                MyBundle:
                    type: annotation
                custom_mapping:
                    type: annotation
                    prefix: Client\IntranetBundle\LDAP\
                    dir: "%kernel.root_dir%/src/Client/IntranetBundle/LDAP/"
                    is_bundle: false

如您所见，最好将所有内容放在 Entity 您的捆绑中的命名空间，并让Doctrine努力工作。

As you can see, it's better to put everything under the Entity namespace in your bundle and let Doctrine do the hard work.
