Doctrine 2 Gedmo扩展无法正常工作并出现错误：“不存在，或无法自动加载”

Question

We are having issues getting Gedmo plugins to work in our ZF 2 Doctrine 2 installation

We are getting this error from generate entities:

[Semantical Error] The annotation "@Gedmo\Mapping\Annotation\Timestampable" in property Wallet\Entity\Entity::$created does not exist, or could not be auto-loaded.

Our entity looks like this:

...
use Gedmo\Mapping\Annotation as Gedmo;
...

/**
* @var datetime $created
*
* @Gedmo\Timestampable(on="create")
* @ORM\Column(type="datetime")
*/
public $created;
...

We have also tried:

/**
* @var datetime $created
*
* @\Gedmo\Mapping\Annotation\Timestampable(on="create")
* @ORM\Column(type="datetime")
*/
public $created;

And

/**
* @var datetime $created
*
* @Gedmo\Mapping\Annotation\Timestampable(on="create")
* @ORM\Column(type="datetime")
*/
public $created;

We have verified that the path is correct and that the php class exists at that path.

Our module config looks like this:

'doctrine' => array(
        'eventmanager' => array(
            'orm_default' => array(
                'subscribers' => array(
                    'Gedmo\Tree\TreeListener',
                    'Gedmo\Timestampable\TimestampableListener',
                    'Gedmo\Sluggable\SluggableListener',
                    'Gedmo\Loggable\LoggableListener',
                    'Gedmo\Sortable\SortableListener',
                ),
            ),
        ),

Our composer config looks like this:

...
"require": {
...
            "gedmo/doctrine-extensions": "2.4.*",
…

We have also tried:

...
"require": {
...
            "gedmo/doctrine-extensions": "2.3.*",
…

None of the articles I have found on the issue have helped so far.

Any suggestions you can offer would be very appreciated.

All the best.

Answer 1

Our developer fixed it over the weekend when we realized that we were missing loading in the listeners in the console.php.

He added them like so: $evm = new \\Doctrine\\Common\\EventManager(); $evm->addEventSubscriber(new \\Gedmo\\Timestampable\\TimestampableListener());

He found his sample code here:
