Questions tagged [spring-data-neo4j-4]

The Spring Data Neo4j project, as part of the Spring Data initiative, aims to simplify development with the Neo4j graph database. Like JPA, it uses annotations on simple POJO domain objects. Together with metadata, the annotations drive mapping the POJO entities and their fields to nodes, relationships, and properties in the graph database.

For version 4, Spring Data Neo4j has been rewritten from scratch to natively support Neo4j deployments in standalone server mode. It uses Cypher, the Neo4j query language, and the HTTP protocol to communicate with the database.

The guide for Spring Data Neo4j 4 is available at http://docs.spring.io/spring-data/neo4j/docs/4.0.0.M1/reference/html/
