Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException：找不到对象

我正在开发symfony2项目，并且我得到了这个异常。任何人有什么想法造成它？未找到带'Gmjob \ ExamBundle \ Entity \ Examination object not found'消息的异常'Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException'。在/数据/阿帕奇/ WWW/emploipublic-SF /供应商/ SENSIO /框架-额外包/ Sensio公司/包/ FrameworkExtraBundle /请求/ ParamConverter/DoctrineParamConverter.php：55 \ nStackSymfony Component HttpKernel Exception NotFoundHttpException：找不到对象

public function apply(Request $request, ConfigurationInterface $configuration) 
{ 
    $name = $configuration->getName(); 
    $class = $configuration->getClass(); 
    $options = $this->getOptions($configuration); 

    // find by identifier? 
    if (false === $object = $this->find($class, $request, $options, $name)) { 
     // find by criteria 
     if (false === $object = $this->findOneBy($class, $request, $options)) { 
      if ($configuration->isOptional()) { 
       $object = null; 
      } else { 
       throw new \LogicException('Unable to guess how to get a Doctrine instance from the request information.'); 
      } 
     } 
    } 

    if (null === $object && false === $configuration->isOptional()) { 
     throw new NotFoundHttpException(sprintf('%s object not found.', $class)); // this is line 55 
    } 

    $request->attributes->set($name, $object); 

    return true; 
}

这里是堆栈跟踪抛出异常：

我会认为这是因为你的'$ object'为空，'$ configuration-> isOptional（）;'方法返回false。 – Ohgodwhy 2014-09-25 06:29:14

您的问题不在于DoctrineParamConverter，它在您的控制器中。

参数转换器是转换参数（好吧，我知道，名称告诉它，但...）的组件。当你写：

public function myAction(Request $request)

设置了一个param转换器会给你Request对象。

当你写：

public function myAction(MyEntityClass $object)

然后DoctrineParamConverter将尝试找到一个主义实体符合路由参数。

我建议从Symfony的文档this article。
