Spring Data Neo4j comes with a number of sample applications. The source code of the samples can be found on Github. The different sample projects are introduced below.

The Hello Worlds sample application is a simple console application. It creates some worlds (node entities) and rocket routes (relationships) between worlds, all in a galaxy (the graph), and then prints them.

The unit tests demonstrate some other features of Spring Data Neo4j as well. The sample comes with a minimal configuration for Maven and Spring to get up and running quickly.

The Hello Worlds application is available both for the simple mapping (hello-worlds) and for the advanced mapping (hello-world-aspects).

Executing the application creates the following graph in the graph database:

The IMDB sample is a web application that imports datasets from the Internet Movie Database (IMDB) into the graph database. It allows the listing of movies with their actors, and of actors and their roles in different movies. It also uses graph traversal operations to calculate the Bacon number of any given actor. This sample application shows the usage of Spring Data Neo4j in a more complex setting, using several annotated entities and relationships as well as indexes and in-graph indexes and graph traversals.

See the readme file for instructions 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. It is basically the foundation for the MyRestaurants-Social application (see???), and does therefore not use Spring Data Neo4j.

This application extends the MyRestaurants sample application, adding social networking functionality to it with cross-store persistence. The web application allows for users to add friends and rate restaurants. A graph traversal provides recommendations based on your friends' (and their friends') rating of restaurants.

Here's an excerpt of the data stored in the graph database after executing the application:

The cineasts.net application was introduced extensively in the first part of this guide, the tutorial. The tutorial covers the development of the simple mapping version of cineasts.

To document the differences, versions for the advanced mapping (cineasts-aspects) and accessing the remote server (cineasts-rest) are also available.

A online version of cineasts can be found on cineasts.net. A sample dataset of the cineasts databse is available at the neo4j sample-data page.

This is a subset of the visualization of the cineasts graph for the "Matrix" movie.
