Php Symfony Rest控制器限制序列化深度

Php Symfony Rest控制器限制序列化深度,php,symfony,fosrestbundle,jmsserializerbundle,Php,Symfony,Fosrestbundle,Jmsserializerbundle,我有许多开发者的实体位和关系,对于开发者,我使用*@Groups({“for_project”}),当我使用这个选项时,作为响应,我没有看到字段开发者,我查看文档,看到*@MaxDepth(2)并使用它,但仍然有null。为什么? { "0": { "id": 501, "created": "2015-11-27T12:25:11+0200", "developer_id": {}, "rate": 4, "comment": "fsefsf" }, "1": { "id": 502, "c

已解决
我明白,需要为fields实体开发者添加*@Groups({“for_project”}) 但当我删除@MaxDepth时,我还有字段实体开发者,为什么需要@MaxDepth?
我理解,当不使用@MaxDept时,我们有关系字段的最大深度,例如我有实体位,位有开发者,开发者有用户,如果我想要可见字段实体用户,我需要在实体位中为字段开发者添加@MaxDept(3)

当不使用@MaxDept时,我们有关系字段的最大深度,示例我有实体位,位有开发者,开发者有用户,如果我想要可见字段实体用户,我需要在实体位中为字段开发者添加@MaxDept(3) 在行动中:

            return View::create()
            ->setStatusCode(200)
            ->setData($bits)
            ->setSerializationContext(
                SerializationContext::create()
                    ->enableMaxDepthChecks()
                    ->setGroups(array("for_project"))
            );

protected $user;

class Users implements UserInterface
{
    /**

/**

protected $lastName;

这适用于我使用fos rest版本:2*和JMS序列化程序版本:3*

return $this->view($data)->setContext((new Context())->enableMaxDepth());

删除@MaxDepth注释时得到了什么?另外,你们能不能显示导入的类?当我删除@MaxDepth时,我还有空的开发者,当我删除*@Groups({“for_project”})时,我有关于开发者的信息。我需要为fields实体开发者添加*@Groups({“for_project”})?我知道我需要为文件添加*@Groups({“for_project”})developer@shuba.ivan将您的解决方案作为答案发布;)很高兴知道你解决了
