Spring数据Neo4j：persist（）方法未定义

Question

Pretty new to graph databases, neo4j and spring. I have a simple POJO annotated with @NodeEntity. But, against the wisdom of many online tutorials I read on the matter, my POJO doesn't have any persist() method to save it to the graph DB.

What sort of black magic do I need to do to make this method available to my POJOs, or are the tutorials out of date and the way to save to DB has changed with the version of Spring I'm using (2.1.0-RELEASE)?

Answer 1

The black magic you're referring to is AspectJ . The advanced mapping mode of Spring Data Neo4j uses aspectJ to enhance your pojos. "persist()" is one of the methods that the aspectj compiler adds to your pojos when building the project.

Check chapter 21 "Environment Setup" in the Spring Data Neo4j Guide Book to see how to setup your project to use the advanced mapping mode with aspectj.
