根据当前配置,没有映射的Doctrine ORM实体

Question

我有一个可疑的问题.我有一组现有的带注释的Doctrine实体,它们已成功用于Symfony2/Doctrine2项目.但是,我目前正在将这个项目的一些核心功能隔离到它自己的Web框架独立库中,我似乎无法让实体正常运行.

目前我主要担心的是Doctrine CLI实用程序给我的结果好坏参半.

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.

我现在已经完成了数十亿次的配置.我甚至删除了所有实体,并在那里留下了一个最基本的用户实体,给了我相同的场景.

什么可能是这些混合结果的来源？

Answer 1

事实证明,标准的Doctrine配置设置[1]不适用于我的代码库,或者我测试过的任何代码库,也许文档已经过时了.在通过Interwebs几个小时后,这是最终使它适用于我的配置:

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');

接受的答案是可以的,但同样的事情可以通过不那么冗长的方式实现:

use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;

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

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

$config = Setup::createAnnotationMetadataConfiguration(
    $paths, $isDevMode, null, null, false
);
$config->setQueryCacheImpl(new \Doctrine\Common\Cache\ArrayCache());
$entityManager = EntityManager::create($dbParams, $config);

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

所有这里都是关于简单注释驱动程序的使用(Setup :: createAnnotationMetadataConfiguration函数的最后一个参数.默认情况下,使用一个简单的注释驱动程序,它不能识别@ORM\Entity注释.
