教义2注释问题

Question

我写我自己的CMS与教义2.5.4和纯PHP 5。

这是我的CMS（谷歌链接）。

在构建过程中，我反驳了这个错误：

错误NewsDAO:异常“条令\ORM\Mapping\MappingException”和消息“Class”News不是有效的实体或映射的超类。'in/var/www/html/xxxxx.com/public_html/vendor/doctor/orm/lib/doctor/orm/MappingException.php:346堆栈跟踪：#0/var/www/html/xxxxx.com/public_html/vendor/doctor/orm/lib/doctor/orm/Mapping/Driver/AnnotationDriver.php（91）：Doctrine\ORM\Mapping\MappingException:：ClassisNoTavalidityOrmappedSuperClass（“新闻”）#1/var/www/html/xxxxx.com/public_html/vendor/Doctrine/ORM/lib/Doctrine/ORM/Mapping/ClassMetadataFactory.php（151）：Doctrine\ORM\Mapping\Driver\AnnotationDriver-

MynewsDAO.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;    
}
?>

mysql中的My tableRich\u news：

+------------+--------------+------+-----+---------+----------------+

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");*/

?

我试图找出我的news.php文件中的错误。为什么没有成功？？？大家能帮帮我吗？？？提前谢谢。

Answer 1

如Doctrine Annotations文档中所述，添加use语句并检查正确的注释（不要为类使用名称空间），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;

希望这能有所帮助
