Php Doctrine2:ReflectionException“with message”类注释在…中不存在，同时尝试在codeigniter控制器中使用条令模型

我收到一条消息：class_parents：当试图在CodeIgniter控制器中使用条令模型时，类注释不存在，无法加载

这是完整的stacktrace 致命错误：未捕获的异常“ReflectionException”，在C:\Users\user\Desktop\projects\Session\application\libraries\Doctrine\Common\Persistence\Mapping\RuntimeReflectionService.php:73堆栈跟踪：0C:\Users\user\Desktop\projects\interview\application\libraries\doctor\Common\Persistence\Mapping\RuntimeReflectionService.php73:ReflectionClass->\uu构造“Comment”1 C:\Users\user\Desktop\projects\interview\application\libraries\doctor\ORM\Mapping\ClassMetadataInfo.php769：条令\Common\Persistence\Mapping\RuntimeReflectionService->getClass'Comment'2 C:\Users\user\Desktop\projects\Session\application\libraries\条令\ORM\Mapping\ClassMetadataFactory.php591:条令\ORM\Mapping\ClassMetadataInfo->InitializeReflectionObject条令\Common\Persistence\Mapping\RuntimeReflectionService 3C:\Users\user\Desktop\projects\interview\application\libraries\doctor\ORM\Mapping\ClassMetadataFactory.php272:doctor\ORM\Mapping\ClassMetadataFactory->在第73行的C:\Users\user\Desktop\projects\interview\application\libraries\doctor\Common\Persistence\Mapping\RuntimeReflectionService.php中初始化

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;
    }
}

这里是doctrine.php

<?php


class Doctrine
{
    // the Doctrine entity manager
    public $em = null;

    public function __construct()
    {
        // include our CodeIgniter application's database configuration

        // 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 = new \Doctrine\Common\ClassLoader('Proxies', APPPATH.'models');
        $proxyClassLoader->register();

        // set up the configuration
        $config = new \Doctrine\ORM\Configuration;

        if(ENVIRONMENT == 'development')
            // set up simple array caching for development mode
            $cache = new \Doctrine\Common\Cache\ArrayCache;
        else
            // set up caching with APC for production mode
            $cache = new \Doctrine\Common\Cache\ApcCache;
        $config->setMetadataCacheImpl($cache);
        $config->setQueryCacheImpl($cache);

        // set up proxy configuration
        $config->setProxyDir(APPPATH.'models/Proxies');
        $config->setProxyNamespace('Proxies');

        // auto-generate proxy classes if we are in development mode
        $config->setAutoGenerateProxyClasses(ENVIRONMENT == 'development');

        // set up annotation driver
        $yamlDriver = new \Doctrine\ORM\Mapping\Driver\YamlDriver(APPPATH.'models\Mappings');
        $config->setMetadataDriverImpl($yamlDriver);

        // Database connection information
        $connectionOptions = array(
            'driver' => 'pdo_mysql',
            'user' => $db['default']['username'],
            'password' => $db['default']['password'],
            'host' => $db['default']['hostname'],
            'dbname' => $db['default']['database']
        );

        // create the EntityManager
        $em = \Doctrine\ORM\EntityManager::create($connectionOptions, $config);

        // store it as a member, for use in our CodeIgniter controllers.
        $this->em = $em;
    }
}

找不出哪里出了问题。我对php及其技术相当陌生。请帮忙。任何有用的想法都会受到赞赏，你总是使用字符串

这一行必须从

$comment=$this->em->find'comment'，1； 到

$comment=$this->em->find'Entities\comment'，1；

---

在字符串中，始终使用

这一行必须从

$comment=$this->em->find'comment'，1； 到

$comment=$this->em->find'Entities\comment'，1；
