用DBRef实现Mongo文档

Question

有许多使用mongo文档Creating BSON object from JSON string的示例

还有一些，但我找不到如何用链接(DBRef)创建另一个文档

就像这样

private static final MessageFormat USER_DBREF = new MessageFormat("DBRef('organizationEntity', ObjectId('{}'))");
...
Document doc = Document.parse(json);
doc.put("organizationEntity", USER_DBREF.format(new Object[]{organizationEntity.getId()}));

Answer 1

   doc.put("organization", new DBRef("organizationEntity", new ObjectId(organizationEntity.getId())));
