Question

我用Doctrine 2.5.4和纯PHP 5编写自己的CMS。

这是my CMS（GOOGLE链接）。

在建设时，我反驳了这个错误：

ERROR NewsDAO：例外＆＃39; Doctrine \ ORM \ Mapping \ MappingException＆＃39;消息＆＃39; Class＆＃34; News＆＃34;不是有效的实体或映射的超类。＆＃39;在/var/www/html/xxxxx.com/public_html/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php:346堆栈跟踪：＃0 /var/www/html/xxxxx.com/public_html /vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/Driver/AnnotationDriver.php(91）：Doctrine \ ORM \ Mapping \ MappingException :: classIsNotAValidEntityOrMappedSuperClass（＆＃39; News＆＃39;）＃1 / var / www /html/xxxxx.com/public_html/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataFactory.php(151）：Doctrine \ ORM \ Mapping \ Driver \ AnnotationDriver-＆gt; loadMetadataForClass（＆＃39; News＆＃ 39;，对象（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-＆gt; 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）：Doctrine \ Common \ Persistence \ Mapping \ Abst ractClassMetadataFactory-＆gt; loadMetadata（＆＃39; News＆＃39;）＃4 /var/www/html/xxxxx.com/public_html/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php（ 216）：Doctrine \ ORM \ Mapping \ ClassMetadataFactory-＆gt; loadMetadata（＆＃39; News＆＃39;）＃5 /var/www/html/xxxxx.com/public_html/vendor/doctrine/orm/lib/Doctrine/ORM /EntityManager.php(281）：Doctrine \ Common \ Persistence \ Mapping \ AbstractClassMetadataFactory-＆gt; getMetadataFor（＆＃39; News＆＃39;）＃6 /var/www/html/xxxxx.com/public_html/vendor/doctrine/ orm / lib / Doctrine / ORM / Repository / DefaultRepositoryFactory.php（44）：Doctrine \ ORM \ EntityManager-＆gt; getClassMetadata（＆＃39; News＆＃39;）＃7 /var/www/html/xxxxx.com/public_html /vendor/doctrine/orm/lib/Doctrine/ORM/EntityManager.php(698）：Doctrine \ ORM \ Repository \ DefaultRepositoryFactory-＆gt; getRepository（Object（Doctrine \ ORM \ EntityManager），＆＃39; News＆＃39;）＃8 /var/www/html/xxxxx.com/public_html/DAO/newsDAO.php(13）：Doctrine \ ORM \ EntityManager-＆gt; getRepository（＆＃39; News＆＃39;）＃ 9 /var/www/html/xxxxx.com/public_html/handler/indexHDL.php(5）：NewsDAO-＆gt; getAll（）＃10 /var/www/html/xxxxx.com/public_html/manager/router.php （22）：require_once（＆＃39; / var / www / html / l ...＆＃39;）＃11 /var/www/html/xxxxx.com/public_html/manager/router.php(18）： Router-＆gt; view（＆＃39; index＆＃39;）＃12 /var/www/html/xxxxx.com/public_html/manager/router.php(13）：Router-＆gt; routing（）＃13 / var /www/html/xxxxx.com/public_html/manager/router.php(8）：Router-＆gt; __ construct（）＃14 /var/www/html/xxxxx.com/public_html/manager/CMS.php(11）：Router-＆gt; getInstance（）＃15 /var/www/html/xxxxx.com/public_html/manager/CMS.php(6):CMS-＆gt; __ construct（）＃16 / var / www / html / xxxxx。 com / public_html / index.php（18）：CMS :: getInstance（）＃17 {main} 注意：未定义的变量：第17行的/var/www/html/xxxxx.com/public_html/DAO/newsDAO.php中的rs

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;    
}
?>

my table中的我的表Rich_news：

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

| author     | varchar(50)  | NO   |     |         |                |
| date       | int(11)      | NO   |     | 0       |                |
| title      | varchar(255) | NO   |     |         |                |
| content    | 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('DAODIR', ROOT_DIR.'DAO'.DS );
define('MNGDIR', ROOT_DIR.'manager'.DS );
define('HDLDIR' , ROOT_DIR.'handler'.DS );
define('TPLDIR', ROOT_DIR.'template'.DS );  
define('SKNDIR', TPLDIR.'skin'.DS );    
define('MDLDIR', ROOT_DIR.'model'.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");*/

＆GT;

我想在我的news.php文件中弄清楚这里有什么问题。为什么没有成功？大家可以帮我吗??? 提前谢谢。

如Doctrine Annotations文档中所述，添加use语句并检查正确的注释（不要为您的类使用命名空间？），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
