Spring Data Graph comes with a number of samples. The source code of the samples is found on GitHub. The different sample projects are introduced below.

The Hello Worlds sample application is a simple console application with unit tests, that creates some Worlds (entities / nodes) and Rocket Routes (relationships) in a Galaxy (graph) and then reads them back and prints them out.

The unit tests demonstrate some other features of Spring Data Graph. The sample comes with a minimal configuration for Maven and Spring to get up and running quickly.

Executing the application creates the following graph in the Graph Database:

A web application that imports datasets from the Internet Movie Database (IMDB) into the graph database. It allows listings of movies with their actors and actors with their roles in different movies. It also uses graph traversal operations to calculate the Kevin Bacon number (distance to an actor that has acted with Kevin Bacon). This sample application shows the basic usage of Spring Data Graph in a more complex setting with several annotated entities and relationships as well as usage of indices and graph traversal.

See the readme file for instruction on how to compile and run the application.

An excerpt of the data stored in the Graph Database after executing the application:

Simple, JPA based web application for managing users and restaurants, with the ability to add restaurants as favorites to a user.

An extended version of the MyRestaurant sample application that adds social networking functionality to it. It is possible to have friends and to add rated relationships to restaurants. The relationships and some of the properties of the entities are transparently stored in the graph database. There is also a graph traversal that provides a recommendation based on your friends' (and their friends') rating of restaurants.
