The title of the post includes “(Part-1)” but all five parts have been posted.
From the post:
In this tutorial, we will create a simple CRUD application using Spring 3.1 and Neo4j. We will based this tutorial on a previous guide for MongoDB. This means we will re-use our existing design and implement only the data layer to use Neo4j as our data store.
I would start at the beginning MongoDB post, Spring MVC 3.1 – Implement CRUD with Spring Data MongoDB. (It won’t hurt you to learn some MongoDB as well.)
Quite definitely will repay the time you spend.
