From http://www.spring.io/projects/spring-data-neo4j

Spring Data Neo4J offers advanced features to map annotated entity classes to the Neo4j Graph Database. The template programming model is equivalent to well known Spring templates and builds the basis for interaction with the graph and is also used for the advanced repository support. Spring Data Neo4j is part of the Spring Data project which aims to provide convenient support for NoSQL databases.

Here is the Spring Data Neo4j reference book.
