【问题描述】：
在此感谢您对我的帮助，我被 symfony 中的教义和 fosrestbundle 的未知行为困扰了一周。
我有 2 个具有多对多关系的实体：产品和类别
自从上周我在 productRESTcontroller 上发送补丁请求以更新实体之间的关系以来，一切正常，在刷新后，通常它会返回更新后的实体。 但是现在，它更新了实体，但它也进行了很多“SELECT”查询，这是我从未做过的。
- 请求是用 guzzle 创建和执行的，它是一个承诺（异步请求）
- productRESTcontroller 是使用 voryxRestGeneratorBundle 与 fosrestbundle 和 jmsserializerbundle 一起创建的
我删除了学说缓存、symfony 缓存等，尝试了许多其他方法来更新实体，但没有解决这个问题。
我可以在日志中看到：

这 6 分钟直到我收到严重错误消息：

提前感谢您的帮助
更新：我终于明白了这个问题。正如 wilt 告诉我的，实体是完全加载的，并且因为每个类别都与产品和产品类别相关，所以每次都会加载很多实体。
一个解决方案是把一些 jmsserialzer 注释，特别是 maxdepth(1) 到加入的实体，并在相关实体上指定一个排除状态，它现在可以正常工作了。

如果我是对的，如果你接受我的回答，那就太好了......
