我在 CodeIgniter 控制器中尝试使用 Doctrine 模型时收到“消息：class_parents()：类注释不存在且无法加载”。
这是完整的堆栈跟踪致命错误：在 C:\Users\user\Desktop\projects\interview\application\libraries\Doctrine\Common\Persistence\Mapping\RuntimeReflectionService.php 中未捕获异常 'ReflectionException' 并带有消息 'Class Comment does not exist' :73 堆栈跟踪：#0 C:\Users\user\Desktop\projects\interview\application\libraries\Doctrine\Common\Persistence\Mapping\RuntimeReflectionService.php(73): ReflectionClass->__construct('Comment') #1 C:\Users\user\Desktop\projects\interview\application\libraries\Doctrine\ORM\Mapping\ClassMetadataInfo.php(769): Doctrine\Common\Persistence\Mapping\RuntimeReflectionService->getClass('Comment') #2 C :\Users\user\Desktop\projects\interview\application\libraries\Doctrine\ORM\Mapping\ClassMetadataFactory.php(591): Doctrine\ORM\Mapping\ClassMetadataInfo->initializeReflection(Object(Doctrine\Common\Persistence\Mapping\RuntimeReflectionService)) #3 C:\Users\user\Desktop\projects\interview\application\libraries\Doctrine\ORM\Mapping\ClassMetadataFactory.php(272): Doctrine\ORM \Mapping\ClassMetadataFactory->initializ in C:\Users\user\Desktop\projects\interview\application\libraries\Doctrine\Common\Persistence\Mapping\RuntimeReflectionService.php 在第 73 行
这是我在 /application/models/Entities/Comment.php 中的模型

这是控制器的代码
<?php
require APPPATH . 'models\Entities\Comment.php';
class CommentController extends CI_Controller{
var $em;
function __construct() {
parent::__construct();
$this->em = $this->doctrine->em;
}
public function index()
{
$comment = $this->em->find('Comment', 1);
echo $comment->user_name . '<br/>' . $comment->comment;
}
}
这是教义.php
<?php
class Doctrine
{
// the Doctrine entity manager
public $em = null;
public function __construct()
{
// include our CodeIgniter application's database configuration
require_once APPPATH.'config/database.php';
// include Doctrine's fancy ClassLoader class
require_once APPPATH.'libraries/Doctrine/Common/ClassLoader.php';
// load the Doctrine classes
$doctrineClassLoader = new \Doctrine\Common\ClassLoader('Doctrine', APPPATH.'libraries');
$doctrineClassLoader->register();
// load Symfony2 helpers
// Don't be alarmed, this is necessary for YAML mapping files
$symfonyClassLoader = new \Doctrine\Common\ClassLoader('Symfony', APPPATH.'libraries/Doctrine');
$symfonyClassLoader->register();
// load the entities
$entityClassLoader = new \Doctrine\Common\ClassLoader('Entities', APPPATH.'models');
$entityClassLoader->register();
// load the proxy entities

$proxyClassLoader->register();
// set up the configuration

if(ENVIRONMENT == 'development')
// set up simple array caching for development mode

else
// set up caching with APC for production mode

// set up annotation driver

// create the EntityManager

不知道出了什么问题。我是 php 和它的技术的新手。请帮忙。任何有用的想法将不胜感激
