Zend2 Framework - Doctrine ORM giving Mapping Exception - zend-framework

Question

I'm trying to use Doctrine 2 ORM for one of my Zend2 applications. I did the setup within the application using Doctrine modules with the help of composer.
I'm able to persist the data to the database, but when i make a find() call on the object manager it is giving me a Mapping Exception, with the following message.
Doctrine\Common\Persistence\Mapping\MappingException
File:
/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/MappingException.php:96
Message:
Class 'User' does not exist
Below are the Doctrine settings added under the Application module config file
'driver' => array(
'application_entities' => array(
'class' =>'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
'cache' => 'array',
'paths' => array(__DIR__ . '/../src/Application/Entity')
),
'orm_default' => array(
'drivers' => array(
'Application\Entity' => 'application_entities'
)
)
)
),
This is the User Entity created under Application\src\Entity folder
<?php
namespace Application\Entity;
use Doctrine\ORM\Mapping as ORM;

return $this;
}
}
Now, when I do persist operation on the above entity from Application module's IndexController, it is working fine. But when I do the find operation using the same object mapper in the same IndexController, it is giving the mapping exception.
Below is how I'm doing this:
$objectManager = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');
$objectManager->persist($user);
$objectManager->flush();
$user = $objectManager->find('User', $uniqueID);
Can anyone help me with this issue??

Answer 1

Your entity is not called User but Application\Entity\User. So replace this line:
$user = $objectManager->find('User', $uniqueID);
With this:
$user = $objectManager->find('Application\Entity\User', $uniqueID);
