分布式tx失败时如何检索错误代码和消息？(How to retrieve error code and message when distributed tx fails? (MS DTC))

 这更多是一个学说2的事情。 
 
 假设您使用注释进行教学映射，则必须声明您在实体中使用的存储库类： 
 
/**
 * @ORM\Entity(repositoryClass="Fully\Qualified\Namespace\To\MyRepository")
 */
class MyEntity { }
 
 如下所述： http : //symfony.com/doc/2.0/book/doctrine.html#custom-repository-classes 。 
 
 然后，您可以使用标准类继承对此自定义MyRepository类进行编码。 
 
 你可以想像这样的事情： 
 
class OrderedRepository extends EntityRepository 
{
    //  some extra methods...
}

class MyRepository extends OrderedRespository {}
 
 最后，如果你想覆盖你的仓库的__constructor，你必须用相同的参数初始化父构造函数： 
 
public function __construct($em, Mapping\ClassMetadata $class)
{
    parent::__construct($em, $class);
    // some extra stuff
}

This is more a Doctrine2 thing.
 
Assuming you are using annotations for your doctrine mapping, you have to declare which repository class you are using in the Entity:
 
/**
 * @ORM\Entity(repositoryClass="Fully\Qualified\Namespace\To\MyRepository")
 */
class MyEntity { }
 
as explained here: http://symfony.com/doc/2.0/book/doctrine.html#custom-repository-classes .
 
Then, you can code this custom MyRepository class, using standard class inheritance.
 
You could imagine something like that:
 
class OrderedRepository extends EntityRepository 
{
    //  some extra methods...
}

class MyRepository extends OrderedRespository {}
 
Finally, if you want to override the __constructor of your repository, you have to initailize the parent constructor with the same arguments:
 
public function __construct($em, Mapping\ClassMetadata $class)
{
    parent::__construct($em, $class);
    // some extra stuff
}
