不是有效的实体或映射类错误

Question

我正在使用Doctrine和Codeigniter。所以我写了一个图书馆班，一起使用它们。但我不能访问实体（在通过反向工程从数据库创建它们之后）。原则给出错误：致命错误：未收集的异常'Doctrine \ ORM \ Mapping \ MappingException'带消息'类操作不是有效的实体或映射的超类。'

我只是添加此代码，这种情况库班和作品的一切权利，但速度很低：

$this->em->getConfiguration() 
      ->setMetadataDriverImpl(
       new DatabaseDriver(
         $this->em->getConnection()->getSchemaManager() 
       ) 
    ); 

我能为这个错误做什么？我产生的实体从DB使用此项功能：

$cmf = new DisconnectedClassMetadataFactory(); 
    $cmf->setEntityManager($this->em); 
    $metadata = $cmf->getAllMetadata(); 
    $generator = new EntityGenerator(); 

    $generator->setUpdateEntityIfExists(true); 
    $generator->setGenerateStubMethods(true); 
    $generator->setGenerateAnnotations(true); 
    $generator->generate($metadata, APPPATH."models/entities"); 

我的行动实体：

<?php 



/** 
* Actions 
* 
* @Table(name="actions") 
* @Entity 
*/ 
class Actions 
{ 
    /** 
    * @var integer $id 
    * 
    * @Column(name="id", type="integer", nullable=false) 
    * @Id 
    * @GeneratedValue(strategy="IDENTITY") 
    */ 
    private $id; 

    /** 
    * @var string $name 
    * 
    * @Column(name="name", type="string", length=45, nullable=false) 
    */ 
    public $name; 

    /** 
    * @var string $nameSafe 
    * 
    * @Column(name="name_safe", type="string", length=45, nullable=false) 
    */ 
    public $nameSafe; 


    /** 
    * Get id 
    * 
    * @return integer $id 
    */ 
    public function getId() 
    { 
     return $this->id; 
    } 

    /** 
    * Set name 
    * 
    * @param string $name 
    */ 
    public function setName($name) 
    { 
     $this->name = $name; 
    } 

    /** 
    * Get name 
    * 
    * @return string $name 
    */ 
    public function getName() 
    { 
     return $this->name; 
    } 

    /** 
    * Set nameSafe 
    * 
    * @param string $nameSafe 
    */ 
    public function setNameSafe($nameSafe) 
    { 
     $this->nameSafe = $nameSafe; 
    } 

    /** 
    * Get nameSafe 
    * 
    * @return string $nameSafe 
    */ 
    public function getNameSafe() 
    { 
     return $this->nameSafe; 
    } 
}
