symfony - Symfony2 自动生成实体错误。

Question

我有两张表 news 和 news_category。为此，我使用 symfony 命令“doctrine:mapping:convert”创建了两个映射类。这两个文件如下。

新闻.orm.yml。

News:
   type: entity
   table: news
   fields:
      newsId:
          id: true
          type: integer
          unsigned: false
          nullable: false
          column: news_id
          generator:
               strategy: IDENTITY
     newsTitle:
         type: string
         length: 255
         fixed: false
         nullable: false
         column: news_title
     newsDescription:
         type: text
         nullable: false
         column: news_description
     newsStatus:
         type: string
         length: 255
         fixed: false
         nullable: false
         column: news_status
     createdAt:
         type: date
         nullable: false
         column: created_at
    manyToOne:
    category:
         targetEntity: NewsCategory
         cascade: {  }
         mappedBy: null
         inversedBy: null
         joinColumns:
            category_id:
                referencedColumnName: category_id
         orphanRemoval: false
lifecycleCallbacks: {  }

2）。新类别.orm.yml

NewsCategory:
type: entity
table: news_category
fields:
    categoryId:
        id: true
        type: integer
        unsigned: false
        nullable: false
        column: category_id
        generator:
            strategy: IDENTITY
    categoryTitle:
        type: string
        length: 255
        fixed: false
        nullable: false
        column: category_title
    categoryDescription:
        type: text
        nullable: false
        column: category_description
lifecycleCallbacks: {  }

之后，我使用了另一个 symfony 命令“doctrine:mapping:import”，我再次在实体文件夹 News.php 和 NewsCategory.php 中生成了两个文件

如下所示。

1) 新闻.php

<?php

  namespace Admin\NewsBundle\Entity;

  use Doctrine\ORM\Mapping as ORM;

 /**
  * News
  *
  * @ORM\Table(name="news")
  * @ORM\Entity
  */
  class News
 {
/**
 * @var integer
 *
 * @ORM\Column(name="news_id", type="integer", nullable=false)
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="IDENTITY")
 */
private $newsId;

/**
 * @var string
 *
 * @ORM\Column(name="news_title", type="string", length=255, nullable=false)
 */
private $newsTitle;

/**
 * @var string
 *
 * @ORM\Column(name="news_description", type="text", nullable=false)
 */
private $newsDescription;

/**
 * @var string
 *
 * @ORM\Column(name="news_status", type="string", length=255, nullable=false)
 */
private $newsStatus;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="created_at", type="date", nullable=false)
 */
private $createdAt;

/**
 * @var \NewsCategory
 *
 * @ORM\ManyToOne(targetEntity="NewsCategory")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="category_id", referencedColumnName="category_id")
 * })
 */
private $category;

}

并且，2）NewCategory.php

namespace Admin\NewsBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * NewsCategory
 *
 * @ORM\Table(name="news_category")
 * @ORM\Entity
 */
class NewsCategory
{
/**
 * @var integer
 *
 * @ORM\Column(name="category_id", type="integer", nullable=false)
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="IDENTITY")
 */
private $categoryId;

/**
 * @var string
 *
 * @ORM\Column(name="category_title", type="string", length=255, nullable=false)
 */
private $categoryTitle;

/**
 * @var string
 *
 * @ORM\Column(name="category_description", type="text", nullable=false)
 */
private $categoryDescription;

}

现在的问题是，当我使用“doctrine:generate:entities”创建实体时，它给了我以下错误。

D:\wamp\www\Symfony>php app/console doctrine:generate:entities AdminNewsBundle
Generating entities for bundle "AdminNewsBundle"

  [Doctrine\Common\Persistence\Mapping\MappingException]
  Invalid mapping file 'Admin.NewsBundle.Entity.News.orm.yml' for class 'Admi
  n\NewsBundle\Entity\News'.

 doctrine:generate:entities [--path="..."] [--no-backup] name

抱歉英语不好请帮我解决这个问题，因为我是 symfony2 的新手

尝试：

1) php app/console doctrine:mapping:convert yml ./src/Admin/NewsBundle/Resources/config/doctrine/metadata/orm --from-database --force --namespace="Admin\\NewsBundle\\Entity\\"

对于 Linux namespace="Admin\\NewsBundle\\Entity\\"，对于 Win 可能namespace="Admin\NewsBundle\Entity\\"

注意映射在正确的位置，具有正确的名称和正确的语法。

2) php app/console doctrine:mapping:import AdminNewsBundle annotation

3) php app/console doctrine:generate:entities AdminNewsBundle

尝试将 YML 的第一行替换为带有 naspace 的实体名称

Admin\NewsBundle\Entity\News:

举个例子。
