PSR-4代码库中的doctrine生成器的解决方法

Question

在我正在尝试的Windows机器上使用Symfony 2和Doctrine

1. 从现有模式生成实体:

   php app/console doctrine:mapping:import --force CoreBundle annotation

2. 在它们上生成getter/setter:

   php app/console doctrine:generate:entities --path=/path/to/codebase/src/MyProject/CoreBundle/Entities CoreBundle

3. 使用Voryx在它们上生成REST CRUD控制器:

   php app/console voryx:generate:rest --entity="CoreBundle:User"

第一步工作正常,我可以在我的CoreBundle/Entity文件夹中找到具有正确命名空间的实体:

MyVendor\MyProject\CoreBundle\Entity

目前很好.但是,运行其他2个命令将失败:

[RuntimeException]
Can't find base path for "CoreBundle" (path: 
"\path\to\codebase\src\MyProject\CoreBundle", destination: 
"/path/to/codebase/src/MyProject/CoreBundle").  

我的composer.json中的自动加载看起来像这样:

"autoload": {
    "psr-4": {
        "MyVendor\\": "src/"
    }
},

我发现Doctrine不能处理PSR-4命名空间,这可能是它失败的原因.

我真的希望这些实体能够存在于PSR-4 CoreBundle中 - 它有解决方法吗？

我试过这个,但它也不起作用:

"autoload": {
    "psr-0": {
        "MyVendor\\MyProject\\CoreBundle\\Entity": "src/MyProject/CoreBundle/Entity/"
    },
    "psr-4": {
        "MyVendor\\": "src/"
    }
},

谢谢.

用户janvennemann在GitHub上修复了PSR-4的Doctrine.您可以在Gist上找到补丁,或在下面链接

一步来解决它

1. mkdir -p app/VendorOverride;
2. cp vendor/doctrine/doctrine-bundle/Mapping/DisconnectedMetadataFactory.php app/VendorOverride/DisconnectedMetadataFactory.php;
3. 应用DisconnectedMetadataFactory补丁;
4. 添加app/VendorOverride到该classmap部分composer.json;
5. 跑composer dump-autoload.

然后几乎所有脚手架命令都有效.
