如何在Zend Framework 2中为Hydator注册Delegator Factory？

Question

Zend Framework 2中的Delegator Factories是一个强大的工具,可以用于创建标准ZF对象,并通过自定义ZF对象进行更改甚至完全复制.

我想为Hydrator创建一个Delegator Factory,以便为它附加一些Hydrator策略.但它还没有工作......

module.config.php

return array(
    ...
    'service_manager' => array(
        ...
        'invokables' => array(
            ...
            'AuthenticationAdapterDelegatorFactory' => 'Foo\\MvcAuth\\Factory\\AuthenticationAdapterDelegatorFactory', // <-- it works
            'DoctrineObjectHydratorDelegatorFactory' => 'Bar\\Model\\Entity\\Hydrator\\DoctrineObjectHydratorDelegatorFactory', // <-- it doesn't
        ),
        'delegators' => array(
            'ZF\\MvcAuth\\Authentication\\DefaultAuthenticationListener' => array( // <-- it works
                0 => 'AuthenticationAdapterDelegatorFactory',
            ),
            'DoctrineModule\\Stdlib\\Hydrator\\DoctrineObject' => array( // <-- it doesn't
                0 => 'DoctrineObjectHydratorDelegatorFactory'
            )
        ),
    ),
    ...
);

由于水合物实际上是由HydratorPluginManager它提供的,我也是这样尝试的:

return array(
    'service_manager' => array(
        ...
        'invokables' => array(
            ...
            'DoctrineObjectHydratorDelegatorFactory' => 'Bar\\Model\\Entity\\Hydrator\\DoctrineObjectHydratorDelegatorFactory',
        ),
        'delegators' => array(
            ...
            'DoctrineModule\\Stdlib\\Hydrator\\DoctrineObject' => array( // <-- it doesn't
                0 => 'DoctrineObjectHydratorDelegatorFactory'
            )
        ),
    ),
    'hydrator_manager' => array(
        'delegators' => array(
            'DoctrineModule\\Stdlib\\Hydrator\\DoctrineObject' => array(
                0 => 'DoctrineObjectHydratorDelegatorFactory'
            )
        ),
    ),
);

那么这里出了什么问题,如何在Zend Framework 2中为Hydrator注册一个Delegator Factory？

Answer 1

你是完全正确的,你必须注册你的水合器类的委托人HydratorPluginManager.问题在于你的关键名称module.config.php.

使用的关键是,hydrators而不是像你有hydrator_manager:

'hydrators' => array(
    'delegators' => array(
        //...your delegators config...
    )
),

我个人认为ZF2配置数组中的密钥命名是非常不一致和令人困惑的.如果您再次遇到类似的问题,请记住这一点.
