Symfony2和Doctrine2：没有为实体“X”指定的标识符/主键。每个实体必须有一个标识符/主键 [英] Symfony2 and Doctrine2: No identifier/primary key specified for Entity "X". Every Entity must have an identifier/primary key
问题描述
我已经复制了确切的例子：成功创建了数据库并创建了表Product。然后，我已经删除了一切，并尝试重新创建数据库（一切都很好）和表（问题！），这只是为了测试目的。
Doctrine不能生成更多的getter和setter，并且无法在MySQL数据库上创建表。
这里有一些输出
app / console doctrine：generate：entities MyBundle
>将Product.php备份到Product.php〜
>生成MyBundle\Entity\Product
（除了创建没有setter / getter的相同的备份文件，没有任何反应）
-
app / console doctrine：schema：validate
OR
app / console doctrine：schema：create
OR
app / console doctrine：schema：update --force
----------
[Doctrine\ORM\Mapping\MappingException]
没有为实体MyBundle\Entity\Product指定的标识符/主键。
每个实体必须有一个标识符/主键。

已尝试到
- 更改项目权限
- 执行app / console doctrine：generate：实体作为根
- 清除缓存
- 执行缓存：清除和缓存：预热
- 手动删除缓存文件夹
php app / console doctrine：cache：clear-metadata&& app / console doctrine：cache：clear-query&&& app / console doctrine：cache：clear-result
但是getter和setter不生成
我试图用
应用程序/控制台原则：schema：drop
但错误总是相同的
[Doctrine\ORM\Mapping\MappingException]
没有为EntityMyBundle\Entity\Product指定的标识符/主键。
每个实体必须有一个标识符/主键。
即使表不存在..
感谢您的帮助
如果您已经转换映射到xml / yml的注释，一定要删除旧的映射文件。
在这个例子中运行： php app / console doctrine：mapping：转换注释
转换： AppBundle\Resources\config\doctrine\MyEntity.doctrine.xml
与此文件内嵌的注释： AppBundle\Entity\MyEntity.php
错误被抛出，因为它在使用注释之前使用xml映射。
删除xml，应该很好。
I'm using Symfony2 to create some dummy projects. I'm keeping to the Symfony2 Book documentation to create an Entity with Doctrine command line (http://symfony.com/doc/current/book/doctrine.html#add-mapping-information). I'm using, thus, annotations, the plain entity Product and no associations.
I've copied the exact example: I've successfully created the database and created the table Product. Then, I've removed everything and tried to recreate the database (everything's fine) and the table (problem!), that just for testing purposes. Doctrine can't generate any more getters and setters and can't create the table on the MySQL database.
Here some output
app/console doctrine:generate:entities MyBundle
> backing up Product.php to Product.php~
> generating MyBundle\Entity\Product
(nothing happens except for creating the identical backup file with no setters / getters added)

My code is exactly as in the Symfony2 Book documentation except for the Bundle name, changed to MyBundle. The structure of files and folders is working properly with other features. There are no particular settings for the project, just the basics.
namespace MyBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity
* @ORM\Table(name="product")
*/
class Product
{
/**
* @ORM\Column(type="integer")
* @ORM\Id

protected $id;
/**

protected $name;

}
Already tried to
- Change project permissions
- Execute "app/console doctrine:generate:entities" as root
- Clear the cache
- Execute cache:clear and cache:warmup
- Manually remove the cache folder
- Keep just the id (as primary key) in the Product entity
- Remove and recreate the whole database
- Remove Product Entity, clear the cache and recreate everything (manually)
- Update all the vendors
- Checked all the double ** for the annotations
- Change computer with the same software architecture
- I've also executed (thanks @Srdjan) php app/console doctrine:cache:clear-metadata && app/console doctrine:cache:clear-query && app/console doctrine:cache:clear-result but getters and setters are not generated
- I've removed the table, database and recreated step by step (thanks @paistra)
I've tried to remove the table with
app/console doctrine:schema:drop
but the error is always the same
[Doctrine\ORM\Mapping\MappingException]
No identifier/primary key specified for Entity "MyBundle\Entity\Product".
Every Entity must have an identifier/primary key.
even if the table doesn't exist..
Thank you for your help
If you have converted your mappings into annotations from xml/yml be sure to delete the old mappings files.
In this example running: php app/console doctrine:mapping:convert annotation
to convert: AppBundle\Resources\config\doctrine\MyEntity.doctrine.xml
into annotations inline with this file: AppBundle\Entity\MyEntity.php
error is thrown because its using xml mappings before it uses annotations. Delete the xml and should be well.
