JMSSerializerBundle：属性 Doctrine\ORM\Mapping\Generated Value：：$strategy 中的注释"@Enum"从未导入

Question

我得到这个错误：

属性中的注释"@Enum" Doctrine\ORM\Mapping\Generated Value：：$strategy 从未导入。做了 您可能忘记为此注释添加"使用"语句？

我只是试图序列化一个分页器对象：

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

这些是我安装的composer.json软件包：

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

将非实体结果传递给序列化程序可能会产生此类错误。

基本上，您不应该将分页器传递给序列化程序，

而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。
