Over at Cake Solutions, Jan Machacek decided to reach out to Neo4j through the graceful abstraction provided through Spring Data Neo4j. But, he is coding it up in Scala. While Java is generally accessible from Scala, Jan points out "some of the sticky points" that you need to consider.
The result of a bit of sensible coding is that Spring Data Neo4j provides the baseline object behaviors, with some implicits bringing out the shine of those objects, for clean integration into Scala.
Read all the details in Jan's original post. Be sure to check out his other Scala posts, including an appropriate look at using Scala's Cake Pattern within a Spring application.
