mongodb:存储分层树结构吗? [英] mongodb: storing a hierarchical tree structure?

问题描述

在mongodb上，我将如何存储分层树数据，其中每个节点都包含一个Java对象，该Java对象包含它自己的一组字符串变量和对象?

on the mongodb, how would I go about storing a hierarchical tree data in which each node contains a Java object containing it's own set of string variables and objects?

如果没有孩子，它将直接进行.但是如何将子节点DBobject作为字段存储在mongodb上?

If there were no children, it would straight forward. but how would you store a child node DBobject as a field on the mongodb?

例如在Jtree上，如果用户单击并选择特定节点上的delete，则应该有一些唯一的标识符对应.

for example on a Jtree, if a user clicks and selects delete on a specific node, there should be some unique identifier that would correspond.

p.s.我可以为每个用户创建一个数据库并让mongodb对该用户进行身份验证吗?

p.s. can I create a database for each user and let mongodb authenticate the user?
