學說2註釋問題

Question

我在寫我自己的CMS學說2.5.4和純PHP 5

這是my CMS（GOOGLE鏈接）。在MySQL

<?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;  
} 
?> 

我的表Rich_news：

同時建設，我反駁這個錯誤：

ERROR NewsDAO: exception 'Doctrine\ORM\Mapping\MappingException' with message 'Class "News" is not a valid entity or mapped super class.' in /var/www/html/xxxxx.com/public_html/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php:346 Stack trace: #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): Doctrine\Common\Persistence\Mapping\AbstractClassMetadataFactory->loadMetadata('News') #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): Doctrine\ORM\EntityManager->getClassMetadata('News') #7 /var/www/html/xxxxx.com/public_html/vendor/doctrine/orm/lib/Doctrine/ORM/EntityManager.php(698): Doctrine\ORM\Repository\DefaultRepositoryFactory->getRepository(Object(Doctrine\ORM\EntityManager), 'News') #8 /var/www/html/xxxxx.com/public_html/DAO/newsDAO.php(13): Doctrine\ORM\EntityManager->getRepository('News') #9 /var/www/html/xxxxx.com/public_html/handler/indexHDL.php(5): NewsDAO->getAll() #10 /var/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): Router->view('index') #12 /var/www/html/xxxxx.com/public_html/manager/router.php(13): Router->routing() #13 /var/www/html/xxxxx.com/public_html/manager/router.php(8): Router->__construct() #14 /var/www/html/xxxxx.com/public_html/manager/CMS.php(11): Router->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} Notice: Undefined variable: rs in /var/www/html/xxxxx.com/public_html/DAO/newsDAO.php on line 17

我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; 
    }    
} 
?> 

我的實體是news.php

我Config.php：

<?php 
ini_set("display_errors",true); 
define('TIMER_START', microtime(true)); 
define('DS', DIRECTORY_SEPARATOR);

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");*/

我試圖找出什麼在我的news.php文件這裏是錯的？ 爲什麼不能解決？ 大家可以幫我嗎？ 在此先感謝。

Answer 1

正如Doctrine Annotations文檔描述，添加use聲明和檢查的權利註釋（不使用命名空間爲您的課嗎？），爲例子：

<?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; 

希望這有助於
