如何在spring数据neo4j中建立这种关系的模型? [英] How to modeling this relation in spring data neo4j?
问题描述
鉴于我有两个实体:人和公司，它们之间存在多种关系:
Given I have two entity: Person and Company, and there are multiple relationships between them:
人员-公司:
- 该人可以是公司的员工
- 该人可以是公司的股东
- 该人可以是公司的法人
公司-公司:
- 公司可以是公司的合法公司
- 公司可以是公司的股东
那么如何在spring数据neo4j中对此建模呢?
So how to modeling this in spring data neo4j?
我尝试建立3种关系类型:EMPLOY，INVEST，LEGAL，每种关系类型均以Company作为StartNode，以person作为EndNode，然后在company and person中，保持这些关系为"UNDIRECTED"方向，与当前图表相同，但是在保存和搜索时始终会出现stackoverflow错误.
What I tried is make 3 relationship types: EMPLOY, INVEST, LEGAL, each relationship type with the Company as the StartNode and the person as the EndNode, then in company and person, keep these relationships with the "UNDIRECTED" direction, just same as the diagram present, but always get the stackoverflow error when saving and searching.
推荐答案
是的，现在这是 github ，所有类都放在sample.spring.data.neo4j包中，并进行相应的测试sample.spring.data.neo4j.repositories.CompanyRepositoryTest
Yes, now here is the solution in github, all the classes are house in sample.spring.data.neo4j package, and the the corresponding test sample.spring.data.neo4j.repositories.CompanyRepositoryTest
一开始的大问题是，它总是抛出 StackOverFlow 异常，这是 lombok 批注引起的，在删除所有lombok批注并使用普通的getter/之后，二传手，一切顺利.
The big issue at the beginning is it always throws the StackOverFlow exception which is due the the lombok annotation, after remove all the lombok annotations and use the plain getter/setter, everything goes well.
