JPA 查询在 postgres 中有效，但在 API 中返回一些空字段
JPA query works in postgres but retuns some null fields in API
我已经在我的存储库中定义了这个函数，在我测试它时它在我的数据库中工作正常并且所有字段都包含值。

然而，当我尝试通过控制器 return 结果时，它 return 有一些空字段（十二月和九月）
this is the result in my database :

最后：这是我的 WorkdaysRepartition 界面
public interface WorkdaysRepartition {

有什么解决办法吗？
