Symfony error The class XXX was not found in the chain configured namespaces XXX
提问by Alberto Fernández
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.
关于这个主题已经有一些其他问题，但没有一个是真正有帮助的。我是 Symfony 的新手，所以很难理解它。
I am in the file Client\IntranetBundle\LDAP\LDAPAuthenticationProvider.php and this code is causing an error:
我在文件 Client\IntranetBundle\LDAP\LDAPAuthenticationProvider.php 中，此代码导致错误：
$user = new LDAPUser($username);
I did add it's namespace which is:
我确实添加了它的命名空间，即：
use Client\IntranetBundle\LDAP\LDAPUser;
LDAPUser implements UserInterface
LDAPUser 实现 UserInterface
The error I get is
我得到的错误是
The class 'Client\IntranetBundle\LDAP\LDAPUser' was not found in the chain
configured namespaces Client\ClientBundle\Entity
What is that suppose to mean? From what I read it has something to do with the mapping.
那是什么意思？从我读到的内容来看，它与映射有关。
My Doctrine orm in the config.yml is set to:
我在 config.yml 中的 Doctrine orm 设置为：
orm:
auto_generate_proxy_classes: %kernel.debug%
auto_mapping: true
Hopefully you can help me.
希望你能帮助我。
EDIT #1:
编辑#1：
Actually, I found out that it was not
其实我发现不是
$user = new LDAPUser($username);
That is causing the error, but it is when I am trying to persist this entity:
那是导致错误的原因，但是当我尝试保留此实体时：
$entityManager->persist($user);
EDIT #2:
编辑#2：
I'm confused with what's wrong with the mapping:
我对映射有什么问题感到困惑：
<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>
Maybe it's because I'm jumping between two bundles?
也许是因为我在两个包之间跳跃？

By default, the auto_mappingfeature looks for entities under the Entitynamespace, so given that your entity is not there, Doctrine does not know anything about it.
默认情况下，该auto_mapping功能会在Entity命名空间下查找实体，因此鉴于您的实体不存在，Doctrine 对此一无所知。
You need to put your entity under the Entitynamespace or configure Doctrine by hand to add your custom entity namespace. This way you lose the auto_mappingfeature, so you would need to register every bundle manually:
您需要将实体置于Entity命名空间下或手动配置 Doctrine 以添加自定义实体命名空间。这样你就失去了这个auto_mapping功能，所以你需要手动注册每个包：
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
As you can see, it's better to put everything under the Entitynamespace in your bundle and let Doctrine do the hard work.
如您所见，最好将所有内容都放在Entity包中的命名空间下，并让 Doctrine 完成繁重的工作。

Your bundle should be mapped with correct entity managers you are using for service / command / api in config/packages/doctrine.yaml(Symfony4) config file.
您的包应该与您在config/packages/doctrine.yaml(Symfony4) 配置文件中用于服务/命令/api 的正确实体管理器进行映射。
For example In following doctrine config, BundleNameis mapped with defaultentity managers so code using defaultentity managers doctrine connection can access and use BundleName's entities and repositories.
例如，在以下原则配置中，BundleName与default实体管理器映射，因此使用default实体管理器原则连接的代码可以访问和使用BundleName的实体和存储库。
orm:
entity_managers:
default:
mappings:
BundleName:

My mistake was that I forgot to add distant bundles/bundles in "vendor" inside my AppKernelfile.
我的错误是我忘记在我的AppKernel文件中的“供应商”中添加远程捆绑包/捆绑包。
They weren't registered in the registerBundles()method.
他们没有在registerBundles()方法中注册。
