教义2注释问题

Question

我正在使用Doctrine 2.5.4和纯PHP 5编写自己的CMS。

这是我的CMS （GOOGLE链接）。

在构建时，我解决了这个错误：

错误NewsDAO：带有消息“类News”的异常“ Doctrine \\ ORM \\ Mapping \\ MappingException”不是有效的实体或映射的超类。 在/var/www/html/xxxxx.com/public_html/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php:346堆栈跟踪中：＃0 /var/www/html/xxxxx.com/public_html /vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/Driver/AnnotationDriver.php(91）：Doctrine \\ ORM \\ Mapping \\ MappingException :: classIsNotAValidEntityOrMappedSuperClass（'News'）＃1 / var / www / html / xxxxx。 com / public_html / vendor / doctrine / orm / lib / Doctrine / ORM / Mapping / ClassMetadataFactory.php（151）：Doctrine \\ ORM \\ Mapping \\ Driver \\ AnnotationDriver-> loadMetadataForClass（'News'，Object（Doctrine \\ ORM \\ Mapping \\ ClassMetadata））＃2 /var/www/html/xxxxx.com/public_html/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php(332）：Doctrine \\ ORM \\ Mapping \\ ClassMetadataFactory-> doLoadMetadata（Object（Doctrine \\ ORM \\ Mapping \\ ClassMetadata），NULL，false，Array）＃3 /var/www/html/xxxxx.com/public_html/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataFactory。 php（78）：原则\\公共\\持久性\\映射\\ AbstractClassMetadataFacto ry-> loadMetadata（'新闻'）＃4 /var/www/html/xxxxx.com/public_html/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php(216）：Doctrine \\ ORM \\ Mapping \\ ClassMetadataFactory-> loadMetadata（'News'）＃5 /var/www/html/xxxxx.com/public_html/vendor/doctrine/orm/lib/Doctrine/ORM/EntityManager.php(281）：Doctrine \\ Common \\ Persistence \\ Mapping \\ AbstractClassMetadataFactory-> getMetadataFor（'News'）＃6 /var/www/html/xxxxx.com/public_html/vendor/doctrine/orm/lib/Doctrine/ORM/Repository/DefaultRepositoryFactory.php(44）：主义\\ ORM \\ EntityManager-> getClassMetadata（'新闻'）＃7 /var/www/html/xxxxx.com/public_html/vendor/doctrine/orm/lib/Doctrine/ORM/EntityManager.php(698）：教义\\ ORM \\ Repository \\ DefaultRepositoryFactory-> getRepository（Object（Doctrine \\ ORM \\ EntityManager），'News'）＃8 /var/www/html/xxxxx.com/public_html/DAO/newsDAO.php(13）：教义\\ ORM \\ EntityManager- > getRepository（'新闻'）＃9 /var/www/html/xxxxx.com/public_html/handler/indexHDL.php(5）：NewsDAO-> getAll（）＃10 / va r / www / html / xxxxx.com / public_html / manager / router.php（22）：require_once（'/ var / www / html / l ...'）＃11 /var/www/html/xxxxx.com/ public_html / manager / router.php（18）：路由器->视图（'索引'）＃12 /var/www/html/xxxxx.com/public_html/manager/router.php(13）：路由器->路由（） ＃13 /var/www/html/xxxxx.com/public_html/manager/router.php(8）：路由器-> __ construct（）＃14 /var/www/html/xxxxx.com/public_html/manager/CMS.php （11）：路由器-> getInstance（）＃15 /var/www/html/xxxxx.com/public_html/manager/CMS.php(6）：CMS-> __ construct（）＃16 / var / www / html / xxxxx .com / public_html / index.php（18）：CMS :: getInstance（）＃17 {main}注意：未定义变量：/var/www/html/xxxxx.com/public_html/DAO/newsDAO.php中的rs 17

我的newsDAO.php

<?php
require_once MDLDIR."news.php";
class NewsDAO{
public function __construct(){}

public function getAll(){   
    global $em; 
    //$tables = $em->getConnection()->getSchemaManager()->listTables();
    //var_dump($tables)--> return a lot of things from database;
    //$classes = array();
    //$metas = $em->getMetadataFactory()->getAllMetadata(); 
    //foreach ($metas as $meta) {
    //  $classes[] = $meta->getName();
    //}
    //var_dump($classes);exit();-->  return array(0){}
    try{    
        //global $em;
        $rs = $em->getRepository("News")->findAll();
    }catch (Exception $e){
        echo "ERROR NewsDAO: ".$e;
    }       
    return $rs;
  }             
}
?>

我的实体是news.php ：

<?php
 use Doctrine\ORM\Mapping AS ORM;
/**
*   @ORM\Entity 
*   @ORM\Table(name="Rich_news")
*/
class News{

/**
*   @nid 
*   @ORM\Column(type="integer")
*   @ORM\GeneratedValue     
*/
public $id;
/** @author @ORM\Column(type="string")*/
public $author;
/** @date @ORM\Column(type="integer")*/
public $date;
/** @title @ORM\Column(type="string")*/
public $title;
/**@content @ORM\Column(type="string")*/
public $content;
/**@full @ORM\Column(type="string")*/
public $full;
/**@title_en @ORM\Column(type="string")*/
public $title_en;
/**@content_en @ORM\Column(type="string")*/
public $content_en;
/**@full_en @ORM\Column(type="string")*/
public $full_en;
/**@flink @ORM\Column(type="string")*/
public $flink;
/**@img @ORM\Column(type="string")*/
public $img;    
}
?>

我在MySQL中的表Rich_news ：

+------------+--------------+------+-----+---------+----------------+
| Field      | Type         | Null | Key | Default | Extra          |
+------------+--------------+------+-----+---------+----------------+

| title      | varchar(255) | NO   |     |         |                |
| content    | text         | NO   |     | NULL    |                |

| flink      | text         | NO   |     | NULL    |                |
| img        | text         | NO   |     | NULL    |                |
+------------+--------------+------+-----+---------+----------------+

我的Config.php ：

<?php
ini_set("display_errors",true); 
define('TIMER_START', microtime( true ) );  
define('DS', DIRECTORY_SEPARATOR );
define('ROOT_DIR', realpath( dirname( __FILE__ ) ). DS );

define('DBN', 'xxxxx' );        
define('HOST', 'xxxxx' );       
define('USR', 'xxxxx' );
define('PWD','xxxxx');
require_once "vendor/autoload.php";

use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;

$paths = array(MDLDIR);
$isDevMode = false;

// the connection configuration
$dbParams = array(
    'driver'    => 'pdo_mysql',
    'host'      => HOST,
    'user'      => USR,
    'password'  => PWD,
    'dbname'    => DBN,
    'charset'   =>'utf8',
);

$config = Setup::createAnnotationMetadataConfiguration($paths, $isDevMode); 
$em = EntityManager::create($dbParams, $config);
//$em->getConnection()->getDatabasePlatform()->registerDoctrinceTypeMapping('enum','string');

/*function exceptionHandler($exception){
    error_log($exception->getMessage());
} 

set_error_handler("exceptionHandler");*/

我试图在news.php文件中找出问题所在。 为什么没有解决？？？ 大家可以帮我吗？？？ 提前致谢。

Answer 1

如“ Doctrine注释”文档中所述，添加use语句并检查正确的注释（是否为类使用命名空间？），例如：

<?php
use Doctrine\ORM\Mapping AS ORM;

 /**
 *   @ORM\Entity 
 *   @ORM\Table(name="news")
 */
 class News{
 /**
 *  @nid 
 *  @ORM\Column(type="integer")  // **my id column is nid** 
 *  @ORM\GeneratedValue     
 */
 public $id;

 /** @author 
  * @ORM\Column(type="string")*/
 public $author;

希望这个帮助
