根据当前配置，没有映射的Doctrine ORM实体 [英] No mapped Doctrine ORM entities according to the current configuration

问题描述

我有一个可疑的问题.我有一组现有的带注释的Doctrine实体，这些实体已在Symfony2/Doctrine2项目中成功使用.但是，我目前正在将该项目的某些核心功能隔离到它自己的独立于Web框架的库中，而且我似乎无法使实体正常工作.

I've got a dubious issue. I have a set of existing annotated Doctrine entities which have been successfully used in a Symfony2/Doctrine2 project. However, I'm currently isolating some core functionality of this project into it's own web framework independent library and I can't seem to get the entities to function properly.

目前，我最主要的担心是Doctrine CLI实用程序给我带来了混合的结果.

At the moment my major concern is the fact that the Doctrine CLI utility is giving me mixed results.

当我执行以下操作时:

bin/doctrine orm:validate-schema

我得到以下输出:

[Mapping]  OK - The mapping files are correct.
[Database] OK - The database schema is in sync with the mapping files.

但是当我这样做时:

bin/doctrine orm:info

我明白了:

[Exception]                                                                                                                                                                             
You do not have any mapped Doctrine ORM entities according to the current configuration. If you have entities or mapping files you should check your mapping configuration for errors.

我现在已经遍历了数百万次的配置.我什至删除了我所有的实体，并在其中留了一个最基本的User实体，这给了我相同的情况.

I have gone over my configuration a gazillion times now. I've even removed all my entities and left a most basic User entity in there giving me the same scenario.

这些混合结果的来源可能是什么?

What could possible be the source of these mixed results?

推荐答案

事实证明，标准的Doctrine配置设置[1]不适用于我的代码库或我测试过的任何代码库，也许文档已过时.经过数小时的Interwebs工作之后，此配置终于使它对我有用:

It turns out that the standard Doctrine config set up [1] doesn't work with my code base, or any code base I have tested with, maybe the docs are outdated. After ploughing through the Interwebs for hours, this is the configuration that finally made it work for me:

use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;
use Doctrine\Common\Annotations\AnnotationReader;

$paths = array( realpath(__DIR__."/../src/My/Entity") );
$isDevMode = TRUE;

// the connection configuration
$dbParams = array(
    'driver'   => 'pdo_mysql',
    'user'     => 'myuser',
    'password' => 's3cr3t',
    'dbname'   => 'mydb',
);

$cache = new \Doctrine\Common\Cache\ArrayCache();

$reader = new AnnotationReader();
$driver = new \Doctrine\ORM\Mapping\Driver\AnnotationDriver($reader, $paths);

$config = Setup::createAnnotationMetadataConfiguration($paths, $isDevMode);
$config->setMetadataCacheImpl( $cache );
$config->setQueryCacheImpl( $cache );
$config->setMetadataDriverImpl( $driver );

$entityManager = EntityManager::create($dbParams, $config);

//-- This I had to add to support the Mysql enum type.
$platform = $entityManager->getConnection()->getDatabasePlatform();
$platform->registerDoctrineTypeMapping('enum', 'string');
