DBRefs（Mongo文档引用）没有急切地获取 [英] DBRefs (Mongo Document references) not fetched eagerly

问题描述

我在最简单的头像中使用Mongo（与Spring Data一起使用）。

I am using Mongo in its simplest avatar possible (in conjunction with Spring Data).

我有两个（第一类）实体（@Documents）A和B ，其中A的引用（@DBRef）为B。创建A和B时一切正常。但是，当读取对象A（通过Id）时，引用B总是 null 。

I have two (first class) entities (@Documents) A and B, where A has a reference (@DBRef) of B within it. Everything works fine when creating A and B. However, when reading object A (by Id), the reference B is always null.

I相信默认情况下会急切地提取DBRef（参见 http://static.springsource.org/spring-data/data-document/docs/current/reference/html/#mapping-usage-references ），但目前的行为是反对的。任何想法为什么？

I believe DBRefs are eagerly fetched by default (see http://static.springsource.org/spring-data/data-document/docs/current/reference/html/#mapping-usage-references), but the behavior currently is against that. Any ideas why?

推荐答案

转移到Spring Data Mongo M5构建解决了这个问题。所以，在那之前一定是个bug。

Moving over to the Spring Data Mongo M5 build resolved this. So, must be a bug until then.
