JMSSerializerBundle：属性Doctrine \ ORM \ Mapping \ GeneratedValue :: $ strategy中的注释'@Enum'从未导入

Question

我觉得这个错误：

  

属性中的注释'@Enum'   从未导入Doctrine \ ORM \ Mapping \ GeneratedValue :: $ strategy。难道   你可能忘记为这个注释添加一个'use'语句？

我只想尝试序列化一个paginator对象：

$paginator = new Paginator($query, $fetchJoinCollection = true);
$serializer = \JMS\Serializer\SerializerBuilder::create()->build();
$jsonContent = $serializer->serialize($paginator, 'json');

这些是我安装的composer.json软件包：

这是JMSSerializer的Github页面上的一个主题：https://github.com/schmittjoh/JMSSerializerBundle/issues/380

将非实体结果传递给Serializer会产生这样的错误。

基本上，您不应该将分页器传递给序列化程序，您应该传递分页器执行结果，因为序列化程序不知道如何处理Paginator。
